One, the condition of the vehicle technology good or bad is also key to fuel-efficient
A car can be fuel, in addition to related to the driver's driving habits, the stand or fall of technology condition is crucial in fuel-efficient car itself, and the stand or fall of technical conditions and vehicle maintenance has a direct relationship. Drivers driving in the usual life, be sure to get into the habit of regular maintenance car.
1. Maintenance of air filter
The function of air filter is clean air into the cylinder, if go over standard or too dirty, prevent the air flow, resulting in increased fuel consumption. The experiment proved that such as fuel oil is too dirty, oil level is too high will increase fuel consumption by more than 20%.
2. Remove carbon
Combustion chamber after the increase in the number of carbon deposition, mixture of spontaneous combustion, to cause the loss of power, if too much, can increase fuel consumption by around 8%.
3. Maintain the muffler
Muffler hinder the discharge of waste gas and power consumption. If muffler burst damage, then will further hinder the exclusion of exhaust gas flow, increase fuel consumption.
4. Check the spark plug
Spark plug is introducing high voltage in the engine cylinders, produce sparks between the electrodes, ignite mixture. According to the test to prove: a spark plug does not work, more fuel consumption by 25%; Two don't work will consume more fuel by more than 60%. And what the size of the spark plug gap, carbon deposition and so on all have direct influence on power and fuel consumption.
5. Adjust the tire pressure
Because the tires after filling in the standard, after a period of time will naturally consume a part of the tire pressure drop, the driving resistance, the service life of tires and fuel consumption has a great influence.
6. Ensure the braking performance
Good braking device can increase the speed of the car moving average technique and transportation efficiency, if the braking performance is bad, it is difficult to guarantee the safety, also affect the engine fuel consumption.
Second, the predictable drive fuel-efficient
Balance the shortest time with the recent distance
Low frequently observed traffic movements
In the face of increasingly high price of fuel, fuel efficient driving became a reality problem facing each owner. In addition to the common experience of the throttle control, vehicle driving fuel economy is an important principle is to be the driver of a prescient.
Before a trip of foresight
Recent balance in the shortest time and distance
Statistics show that, when idle, the fuel consumption and moving the fuel consumption ratio of 1:5. Therefore the owner considering daily travel route, driving distance is not the only choice based on the recently, the owner is also concerned about this line congestion at the same time, is there too much traffic, intersection, etc. In order to achieve more fuel-efficient, owners at the same time in the road when the choice should be the nearest and the shortest time.
Driving in foresight
Five forms driving skills
In the process of driving in favor of the five forms of fuel.
The hills with beef: in the process of driving, the driver should think of some way to be able to see the front of the vehicle in front of the vehicle, this call the hills with beef. When driving car can be a quarter of the shunt the orbital, such not only can see the vehicle ahead at the vehicle ahead of vehicles can also be clear at a glance.
Enemy ahead: learn to view distance, while driving, according to the surrounding environment, judge each other. Is preparation, which can reduce unnecessary movement. Such as slammed on the brake, fierce boom throttle because the driver did not determine in advance, when driving conditions change passive measures.
Gaining momentum: the driver 500 meters in front of the slope should be slight acceleration, so that when a real uphill, we can reduce the strength of the on the accelerator don't even have a special gas, but more to use natural slowdown to slope.
Vision: the driver to put away, the line of sight to see the traffic lights in front of the early, in front of the crossroads or toll station, can advance receiving, slowly to reduce the speed, smooth arrival.
Follow: drivers to pay attention, such as when the red light release the current car's brake lights show that vehicle ahead when ready to start, then to car drivers also should be ready to start. That will make early preparation, the smooth start, not in order to keep up with the vehicle ahead, narrowing the distance and the accelerator pedal. Three, small gasoline common sense: do you know the meaning of gasoline label? When we say no. 90, no. 93, no. 97 unleaded gasoline, do you know the meaning of the gasoline label? The so-called no. 90, no. 93, no. 97 unleaded gasoline, means they contain 90%, 90% and 93% respectively of antiknock ability of isooctane, meaning contains 10%, 10% and 10% respectively of n-heptane antiknock ability is poor. Then, is the octane number of gasoline engine on antiknock ability index. Should use 97 # gasoline engine, if use 90 # gasoline, of course, prone to detonation.
The engine compression ratio and detonation
Use cars at present most is the so-called four stroke engine, it is the use of the piston in the cylinder reciprocating motion, with "air intake, compression, eruptions, exhaust" four stroke, inhalation of air and fuel mixture, and then compress it, then use the spark plug point it and gain momentum, after get motivated, and deployment of exhaust fumes.
First, we need to understand is that four stroke engine with the fuel is not necessarily the gasoline, compressed natural gas, liquefied petroleum gas, alcohol, even is available for use as a fuel engine. Gasoline is will become a main fuel, because it is relatively easy to obtain, is easy to store, relatively cheap.
Because of engine can use a variety of fuel, therefore, in the early development of the engine, engineers have made many attempts, in addition to try different design have different engine performance, also try to use different fuels will get different effect. It was found that when other things being equal, as long as the higher the compression ratio of the engine will get more power output. Compression ratio is not, however, can be unlimited increase, when carry too high compression ratio, the engine will appear detonation phenomenon. So-called detonation, oil/gas mixture is compressed, before haven't spark plug ignition, because be caused by the compression stroke lit, the heat of the gas molecule movement formed the so-called spontaneous combustion phenomenon, then the spark plug ignites compressed again oil or gas mixture, two group high-explosive fireball violent collisions in the combustion chamber, creating like knocking at the door of "cascades, cob, cob" sound. After careful research, the engineers found that the detonation and fuel choice about again, if the right fuel, so even if the engine compression ratio, also won't knock.
Detonation and the octane number
Know the relationship between detonation and fuel, engineers started produced in the refinery, can be used as the various engine oil by testing and experiment, the results found that antiknock effect is the worst "n-heptane", so the engineers give the strongest earthquake resistant index 100 isooctane, while the worst n-heptane gave it a seismic index of 0. So, from now on, the discretion of the octane number is gasoline engine of antiknock ability index.
So what is the octane number? Is that the engineers in the laboratory, using an adjustable compression ratio measured by a single cylinder engine test data. In the experiments, with the increasing of compression ratio, never knock, combustion test fuel flow condition, began gradually adjusted to knock. When detonation began to appear, is to compare the status of the mixture of isooctane and n-heptane, if there is a knock the condition of the time, as it happens and 97 isooctane and 3 copy of n-heptane the same test condition, so the test fuel octane number is 97. So, when we say no. 90, no. 93, no. 97 unleaded gasoline, its octane number is actually a ratio.
Correct selection of the gasoline label
For many owners, gasoline label is the product purity and quality standards, use label the better the higher gasoline vehicles, this idea is wrong. The discretion of the gasoline label just said the size of the gasoline octane number, depending on the engine compression ratio should be to choose a different grade gasoline. Compression ratio between 8.5 9.5 intermediate-grade cars should generally use 93 # gasoline; Compression ratio is greater than 9.5 cars should use 97 # gasoline. At present domestic car of compression ratio in 9 or more commonly, it is best to use 93 or 97 # gasoline.
If choose high compression ratio of engine, low grade gasoline can make the cylinder temperature rises, the incomplete combustion of gasoline, strong vibration machine, so that the output power down, damaged parts. Low compression ratio of stubbornly high grade engine oil, can appear "delay" phenomenon, namely the pressure in the head it is less than spontaneous combustion point, as will appear incomplete combustion phenomenon, the engine is no good.
Four, domestic automobile oil-saving secrets "fuel" has become the most fashionable car gens of vocabulary, also is one of the talk of owners, owners fuel-efficient driving skills to the attention of a degree is higher and higher. As is known to all, fuel consumption and largely with the use of the driver, use environment, repairs and maintenance of quality has a direct link. The same one car, driven by different drivers, and due to different level of driving technology, fuel consumption can vary from 8% to 15%. In order to make your "horses" running well, and let the "horses" less "eat grass", reporter ask king oil-saving contest of the best fuel-efficient several fuel-efficient, now the disclosure of the following:
In the process of the car, want to look for the thermometer, engine normal water temperature should be kept between 80 ℃ to 90 ℃, excessive or insufficient can increase fuel consumption. In particular, if the tank water shortage, could easily lead to water temperature rising rapidly, when the temperature exceeds 95 ℃, 30% - 30% increase in fuel consumption than the normal temperature, and could easily lead to wear and damage to the machine elements.
Always check the pressure of the tire, to remain in the best state. To ensure correct tire pressure, air pressure is insufficient will increase fuel consumption, so you should check the tire pressure regularly. As long as there is a tire is less 40000 PASCAL (KPa), the tires will reduce the service life of 10000 km, and make the car more than the total fuel consumption by 3%.
Don't change the size of the tire. Select wider tires may make your car looks more "sports car", but the tyre is wider, wheels, the greater the resistance will be a waste of gasoline. Besides tyre diameter if increase, will increase the working load of engine, and the fuel consumption increase.
With the lowest viscosity of engine oil. You should have instructions on your car manual car's ability to use the lowest engine oil viscosity. Engine oil viscosity is lower, the more the engine "effort", and more fuel efficient.
Don't warm up too much. Some owners like before driving in the morning, warm up before the road, this is a good habit, but warm up too long is no doubt with my purse. In addition, you can also let the car drive slowly at first two kilometers to reach the effect of warm up.
Don't speeding. For general motors, the speed of 80 kilometers per hour is the most fuel-efficient, statistics show that every increase 1 km per hour, will give you a 0.5% increase in fuel consumption.
In guarantee under the condition of safety, can use in a way that is neutral taxiing fuel efficient, but also have the personage inside course of study thinks DianPenChe can with slide block to fuel-efficient.
After cleaning your car compartment. Extra things, no matter it is a pair of shoes that are seldom used, or half tank with remaining oil, will increase the burden, the car is also increase the burden of your pocket.
Fifth, oil-saving DianPenChe driving habits Due to the type of the vehicle and driving habits vary, the fuel consumption will have a big difference. This requires us to understand the working principle of the vehicles, reasonable use correctly, in order to achieve the utmost to save fuel.
There are a lot of people think the "automatic" is infinitely variable speed, throttle a throttle, speed automatically rise, but in fact it is just automatic shift. So we need after the start, in every engine speed reaches 1500 ~ 2000 turn the throttle back, let it have a shifting process. Even if the speed of the car has reached more than 100 kilometers per hour, when you come back a throttle, to hold the throttle, you'll see the engine speed at this time only within the 2500 RPM, but can steady speed above 120 km, the fuel economy of cans be imagined.
Thus, each owner needs to have a good driving habits, under the engine speed of reasonable shift, (" the manual "or" automatic ") reduces the speed, steady gas on the highway, with a relatively low engine speed to maintain the speed, reasonably extend the sliding distance, will greatly improve fuel economy. Six, drive fuel-efficient seven small skills effectively
A magic weapon: soft start hanging low
To start, slowly on the gas pedal and slow speed. When the car reaches a certain speed range, learn to listen to the sound of the engine to gradually from DiHuan to high range. It can reduce the heating time of engine, increase the utilization rate of fuel. If the startup boom down to speed up, such not only hurt the car will also greatly increase the fuel consumption.
Magic weapon 2: use economic speed
General car speed of economy in 60 km/h and 80 km/h. When cars run in the economic speed is one of the most fuel efficient, both speed too high or too low on fuel. Low speed, low rate of movement of the piston, the incomplete combustion. High speed, the inlet velocity increase lead to air intake resistance increased, the increase of fuel.
Magic 3: light up the gas
Can light up the gas fuel efficiency. If heavily accelerator, will reduce the engine speed suddenly and lead resistance effect, offset part of inertia, and make the car produces "vibration", and increase fuel consumption.
Magic weapon 4: shift in time
Shift faster and timely, especially on the slope, the shorter the time shift, the car's performance will play better, more can save fuel. If the shift is not timely, and put the pedal to the empty hands bad cooperation will greatly increase fuel consumption.
Five: magic weapon to use less braking
Braking is essentially a process of energy conversion, brake means that the consumption of energy. So is through the intersection, downhill, should be raised in advance the throttle, if the car performance is good, can also be idling cars and car natural slowing down to reach the purpose of "slip for brake".
Magic weapon six: stay with distance
If road congestion and the vehicle ahead and often the brakes, you should keep enough distance with the car and the vehicle ahead, so that you can either easy reduction, can reduce the number of braking, in order to achieve the purpose of fuel economy.
A magic weapon for seven: high quality vehicle fuel economy
Generally speaking, as far as possible, using high-speed gear driving, less in the middle gear.
Of course, don't run on the high gears to pull over. Learn to listen to the sound of the engine to shift, and to understand your own car. When the engine before the "shaking", cut down the block, to speed up again in return for high quality.
Seven, fuel-efficient four tips for your car use to save fuel
Gasoline prices rise again, a heartbreaker let motorists. Drive, gasoline is quite expensive, does not open, is it into decoration car? You don't worry, I have here a few action fuel-efficient methods, you might as well try, may be able to receive the unexpected effect.
Lubricating oil and engine oil
Regularly check engine lubricating oil and engine oil quantity. This is because the mechanical friction exists between the friction will make the engine power to waste on the friction resistance, then you will pay the corresponding gas money, to do the impossible. Lubricating oil and engine oil to the mechanical friction between the lower and reduce the power consumption of the engine, and in order to achieve the purpose of the fuel and prolong mechanical life. Some fixed number of year long car, have a bad habit of "burn" oil will add oil once a week on average, if you feel your car fuel consumption continues to rise, then check the all kinds of oil, perhaps problems will be readily solved. In addition it is important to note that your car manual will show the car's ability to use minimum engine oil viscosity, the lower the viscosity of engine oil, engine, the "save".
Keep the "/" clean
Suspension with a lot of dust in the air, the suspended particles mainly of silica Sio2 - a more hard than the metal material. Install the air filter can reduce the wear of cylinder, piston and piston ring parts. If the car is not installed air filter, or clean air filter for a long time, and cylinder wear will be increased by 7 times, piston wear 3 times, an eightfold increase in piston ring wear, while fuel consumption rose 5% % ~ 10% %. At present more popular is a low quality, low cost, easy to change, high filtration efficiency of paper filter dry type air filter, usually once every 5000 km clean. When cleaning, should remove the filter, gently wash, do not use gasoline or water per 25000 km print cartridge must be replaced.
Internal combustion engines in use process, mechanical impurities such as dust, scrap metal, carbon deposit would continuously mixed with oil, and at the same time air and combustion exhaust gas has the oxidation of oil, and the oil gradually produce gelatin, mechanical impurities, oil sludge mixed with glue will not only does this accelerated motion parts wear, and easy to cause oil plug. In order to ensure the cleaning of oil, when the oil change must also change the oil filter.
Gasoline in the process of storage and transportation and charging, hard to avoid can mixed with some mechanical impurities and moisture. These impurities with fuel oil into the oil supply system and engine cylinders, cylinder will accelerate wear. After filter blockage, will make delivery pipe resistance increased, carburetor oil supply shortage, cause mixture a lean, engine power drop, increase fuel consumption. Before gasoline into gasoline pump, therefore, must be filtered, to guarantee the normal work of the gas supply system. Most of engine jacket is a one-time cannot unpick and wash type paper filter fuel filter, change cycle is commonly 10000 kilometers.
The correct use of tyre
Tires for cars like people's legs, the legs if there is anything wrong, will be very difficult to get up so people walk. For tires, to check whether the tire is often excessive wear and tear, and more than "tire lifeline". Tread pattern design is very scientific, its main function is to enhance the tyres grip, maintain the tire and ground forces, when the tire wear to a certain extent, the tire will be wandering in the process of driving, the phenomenon such as sliding, besides will pose a threat to security, also because cars drive abnormal, due to increased fuel consumption.
The pressure of the tire is very exquisite, low or high air pressure, increases fuel consumption, reduce the service life of the tyre. Because the tyre bear the weight of the whole body and internal passengers, if the air pressure is too low, will increase the tire friction with the ground, make a power output increases, increase fuel consumption. And air pressure is too high, can make the automobile vibration reduction effect, meet bumpy road, cars crawling capacity will reduce, such as step on the gas, the fuel consumption will increase. Car when a tyre is less 40000 PASCAL, the tires will reduce the service life of 10000 km, and make the car more than the total fuel consumption of 3% %. So check the tire pressure regularly, it is very important.
Develop good driving habits
Some friends like to play in the engine preheating before driving in the winter, the habit is very good, because the engine work in under the condition of low temperature, can drop the work efficiency, serious still can reduce the service life, a timely hot car, will make the engine into the "best" state. But warm up too long is certainly got her knife in his pocket, often hot car need only 3 ~ 5 minutes, if more than this range, it really is in the "burn".
In the process of driving accelerator pedal of avoid by all means to speed up, this will only increase the fuel consumption, it saves much time. For general motors, there are economic speed. Usually, at 80 kilometers per hour, should be the most fuel-efficient.
Last before we leave, take a look at your load. Is there some useless things to increase the weight of the car? Even if is a pair of sneakers, or some magazines, will contribute to your high fuel consumption, superfluous, throw it away, let us easily on the road, "money" way will be boundless.
Eight, the best transport method result summary - fuel economy
To fuel efficiency, save money, but also conducive to environmental protection, is the best way to make the car running in normal circumstances, this is many of the owners of the conclusions. They think that reduce fuel consumption and improve vehicle performance must do the following work: one is to use the high quality product (including fuel and all kinds of lubricating oil); 2 it is regularly for a variety of maintenance and maintenance; 3 it is to have good driving habits. Specific experience is as follows:
1, adjust engine. Fine accurate calibration and maintenance of the engine fuel consumption is low, less emissions of pollutants.
2, for routine maintenance. Ann according to automobile manufacturers to provide maintenance plan regularly check the fuel system, air filter, transmission, steering system and brake system, belt, air conditioning, shock absorber, wheel alignment, and other various easy wear and easy broken parts.
3, smooth acceleration. Start and stop to avoid too fast too quick, "three start shaking, parking a bow" certainly not conducive to fuel-efficient. According to data shows: start too fast to make motor overload, cost 60% more fuel than normal for driving.
4, the speed properly. Speed too slow or too fast will make car fuel consumption by increasing, in general, moderate speed more fuel-efficient. At the speed of 105 km per hour, per liter of gasoline less than run at 90 kilometers per hour is 0.85 kilometers long.
5, driving at a constant speed. Unnecessary acceleration, deceleration, or parking will increase fuel consumption.
6, using high quality oil. Engine oil is one of the most important protection product car, good quality oil can prolong the service life of the engine, but also can reduce fuel consumption and emissions. Owners need to periodically check the oil and oil change on time.
7, tire pressure properly. Check the air pressure of the tire, tires under-inflated increases fuel consumption. The data show that, when the tire pressure is lower than prescribed pressure 4.9 mpa, will increase about 2% of the fuel consumption.
8, the combiner pedal movement, it is easy to cause an emergency brake on the brake pedal, bring danger to themselves and the car and unexpected trouble. In addition, the car condition is a factor to ensure peace moment, tire pressure is normal; Oil is enough; Whether to keep water temperature in normal; If there is any change of braking effect; Engine working with and without exception, are to pay attention to at any time.
9, tells the car after the brake pedal, then slow down. If it is without ABS system, should use "see" type "snub" to make the speed gradually reduce, avoid by all means "a feet qiankun", to prevent wheel lock skid. If there are ABS system, one foot in place, otherwise can't effective braking.
Nine, experience about security gap with gear taxiing and fuel consumption
Neutral taxiing is driving in receiving slide and push the gear to the neutral position, Joe slide block is not to pick a slide block directly receiving. Has two kinds of approach are compared in two sides, the center of the discussion on which is more fuel efficient. Personally, I think, the effect of two ways in terms of fuel efficiency is has long have short, different conditions have different performance, but two ways on safety has bigger difference. Drive in the long run should be understand gradually evolved after driving skills from unfamiliar to the familiar adult knee-jerk reaction, so good driving habits, driving at a crucial moment has a crucial effect on treatment, tell a thing happened in my own.
Originally I is also used to neutral taxiing, listen to the old driver and driving school teachers are told not to neutral, so whenever meet slippery or rain and snow road just remind yourself is not neutral, thus opened several years also out of nothing. To named bei haidian DMV, one year winter, in the morning to go out when it begins to snow to named bei mountain road when the ground is a thick layer of snow. Less cars in the mountains, rolling over the snow ice formation, more smooth. Open open far saw in front direction there was a man pushing a bicycle, in the back seat for a woman, they step on the snow slips of walking, several desire to slip and fall. Because the narrow road, if they slip I'm afraid when I go beyond the consequences will be serious, and then slow down to their left farther away from the past. When we are becoming more and more close reverse came to a big, because it is a corner, both sides have to the other side of the tree I can't see, so it appears very suddenly, if I don't increase the slow passing each other so we just in the three point one line, narrow road, I will close to the pedestrian. So I started with brake. Too focused on the road, subconsciously driving habits at ordinary times is reflected: unconsciously pick the belt brake, trample is not heavy. Car to slow down slightly, then feel tire lock and lose the direction control began to run to the right (luckily not left, the main public I left whizzing), I quickly brakes, step on the clutch and gear, to restore control. Car after the clutch suit moments have a sense of direction, gave a car to the left and then again out of control and begin to slide again turn again to the right, the watch is getting closer and closer to the side of the road drainage (the drain is not the pediatrician in "initial D", is the north side of the road before common that a deep ditch, put it in half the xiali is not a problem). See revised hopeless head is more clear, thinking of the arms to her chest to protect themselves?
Like all dangerous moments every second change slowly, watching the car slide with the slow motion in the movie, the taxi's special cold in my heart, can't control, I don't know where it will go, my mind only to the worst, even see the picture of the elderly. Life is really good, the car hadn't slipped into the gutter, crashed into the side of the road tall poplar trees, fell in the snow windshield up into something like frosted glass pervious to light opaque shadows. Look from the side window body and driving direction turn 180 °. In the car seat has for a long time (how long specific don't know, anyway, silly for half a day), surrounded by a sound all have no, with a coffin, engine to destroy any more, only the instrument on the stage a few red light especially dazzling. On a cold got out to examine the loss, with the final loss left width modulation, left turn, left headlight, bumper, fender, machine cover, front longeron deformation end of the journey. Slide from the things again after not neutral, when no matter what happens, even reversing downhill hang up the reverse gear.
An accident probability is very small, but no matter how small, one over one thousand, one over ten thousand, catch is one hundred percent. If there were no crashed into the tree but hit a pedestrian and even more in the mountains a couple kiss parents, fuel-efficient province clutch, is better not to have an accident.
Neutral and slide block which fuel efficiency has always been a matter of debate, in both cases will fuel economy but actually depends on the specific circumstances, can't say anything which fuel efficiency.
Neutral taxiing fuel-saving mechanism is the idle state of fuel consumption is smaller than any driving state. Slide block mechanism of fuel economy is efi engine oil cut-off in supporting dynamic conditions. Low idle speed fuel consumption is better understood, broken oil need to explain: DianPenChe driving computer roughly eight kinds of conditions to control the engine, including dynamic condition. When the throttle all season valve in idle speed switch will be closed, and the crankshaft speed higher than idle state, the driving computer infer that the engine is in dynamic conditions and stop injection.
But stop injection is also restricted by some conditions, in a first driving computer three and moving condition related to the preset speed: break point, restore injection point and emergency recovery injection point.
Break point: the engine speed is higher than the point into the dynamic condition, the computer is stop injection, lower than the preset value into the dynamic condition is oil, engine drive wheels against, passive work.
Spray restore point: to prevent engine flameout, the computer before falling speed to high idle speed recovery oil, make the engine continues to take the initiative to work.
Emergency recovery injection point: when the speed decreases sharply, for instance, driving a computer will be higher than that of spray restore point injection to prevent engine flameout and higher speed recovery at the same time can also provide more reserves of vacuum brake booster.
(the interpretation of all models are the same, different models or different versions can have different ways to deal with computer, is roughly the same)
So while driving:
1. If the engine speed is not high, neutral taxiing are more fuel efficient, whereas in more fuel-efficient.
2. Long slide on a level road, neutral than baffle distance, more fuel efficient.
3. The long downhill glide for oil cut-off mechanism, block than neutral gas.
Above only for manual scotch and early automatic buffer. New automatic buffer many designed for receiving after a period of time to idle speed automatically. In view of the above examples, however, I personally don't recommend neutral, not safe. To know these and reasonable use tend to have very good effect, such as mountain roads open air conditioning when long downhill slide block, not only fuel can also enjoy free air conditioning.
