How to save gas by stepping on the accelerator when driving?

I often see different cars on the Internet mainly for fuel consumption. Some people have different models of the same series. For example, Haval H6 has many styles and is dazzling. There are two generations of H6, three generations of H6, and national trend version of H6, and it is also divided into 1.5 T and 2.0T have different engines, if the models are different, the specific fuel consumption is meaningless.




But the same car, driven by different people, has different fuel consumption. Let’s take the Haval H6 as an example. The same car, some people drive on urban roads every day, and generally do not run fast on urban roads, and there are countless traffic lights. There are also traffic jams. An average speed of 20-40 km/h is not bad.

Some people run on national and provincial highways every day at a speed of 50-80 km/h, and some people run on the highway every day at a speed of 100-120 km/h.

The fuel consumption of these three conditions is also different. Take the 1.5T third-generation H6 as an example, the fuel consumption of running on urban roads is generally about 10~14L, and the fuel consumption of running on national highways and provincial roads is generally 6~7L per 100 kilometers. The fuel consumption for running on the highway is generally 7~8L, which is specially tested fuel consumption.




Therefore, some people say on the Internet that my H6 is super fuel-consuming, with a fuel consumption of more than 10L per 100 kilometers. They are also right. When driving in the city every day, the speed is inherently uncontrollable. In addition, when you stop and go, The high fuel consumption is not surprising, but it does not mean that the fuel consumption of the H6 is high. This is a road problem. Some people run national and provincial roads every day with only 6~7L of fuel. So how do you say?

Finally, the average fuel consumption of H6 is about 7~9L. If calculated at 7 yuan per liter, the fuel cost per kilometer is 0.49~0.63 yuan, and the average is 0.56 yuan, which is not too high. Right.

This is a situation where the fuel consumption is different when running on different roads. In fact, even on the same road, different people driving the same car, the fuel consumption is also different. Why is this?

The reason is that everyone’s driving habits are different.

The driving habits that affect fuel consumption mainly include the following:



1. The throttle is often heavy.

It is the most fuel-consuming driving habit to frequently accelerate with the accelerator pedal. There is a process for the engine to inhale gasoline. When the accelerator pedal is refueled, the amount of compressed gasoline entering the combustion chamber suddenly increases, and the heat energy cannot be turned into kinetic energy immediately. A series of procedures are first transmitted to the gearbox, and finally to the power system.

Besides, the speed of your car is gradually increasing. No matter how powerful the car is, it will take a few seconds to accelerate from 100 kilometers. The average family car is longer. Only part of the fuel added by the big foot is used, and part of it is pure waste. So, the driving habit of refueling with big feet is very fuel-intensive.

2. Frequent braking.

Frequent braking is also very fuel-consuming. Our family cars are generally hydraulically braked. When you step on the brakes, the brake fluid will transmit the braking command to the brake system, and finally transmit the pressure to the brake calipers, which is generated by the wheels. Friction and slow down the vehicle.



When you step on the brake, the speed of the car will decrease, and the power of the engine will decrease. Then you can’t stop the car. If you want to continue driving, you have to refuel, and then you have to give the engine enough gasoline to recover. Up to the previous speed, this process is fuel-consuming and also caused by braking. When you brake frequently, the speed of the car changes greatly and it consumes more fuel.

3. Super high speed driving.

Generally refers to illegal speeding. The most economical speed for a car is 80 km/h. If the speed exceeds this speed, the consumption of gasoline will greatly increase. Because the car is fast, the wind resistance is large, and the resistance generated by the car is large. More power is needed to overcome resistance, that is, more oil is needed.

This is also the reason why high-speed highways are more fuel-intensive than provincial national highways. However, most national highways run at a constant speed. If national highways have more speed limits or when there are many traffic lights, fuel consumption will be higher than that of highways.

4. Driving at ultra-low speed.




Ultra-low speed driving refers to driving at a very slow speed, which is lower than the normal driving speed. For example, running 20-30 km/h on a national highway. If you run like this for a long time, the engine will be in a low-power state for a long time and the combustion will not be sufficient. It consumes gasoline. This principle is similar to the slow stop-and-go speed in the city.

5. Long idle speed.

Idle speed refers to the state that the car engine is running in neutral gear. At this time, the engine only maintains basic work and does not distribute energy to the power system, but the oil is constantly being consumed. To put it simply, the engine is not working and the car is idling. Fuel consumption is generally about one liter per hour, depending on the size of the displacement.

If you idling for a long time, your car consumes gasoline, but does not move forward, it is a waste. Try to reduce the car idling for a long time to save fuel. Of course, a relatively short idle speed does not affect, such as a manual transmission car sliding in neutral before a traffic light. , Is fuel-efficient.

Different people drive different fuel consumption. Most of these driving habits are different. You can see if you have these habits, then how to step on the accelerator to save fuel?




There is a principle of fuel saving when stepping on the gas pedal: refueling at a constant speed, driving at a constant speed is the most fuel-efficient.

I mentioned the bigfoot throttle membership fee. How do I increase it when I refuel? Refuel at a constant speed, that is, keep the speed of stepping on the accelerator at a constant speed, and don’t step on it violently.

As we all know, the engine is the most fuel-efficient when it is in the best working condition, that is, the speed is kept at a constant speed. How to keep the speed at a constant speed? Just step on the accelerator to keep it constant, and the vehicle speed will not change much. But when driving, there will always be situations like this. How to keep the speed even?

There is a method called: predict in advance and use less brakes.



In non-emergency situations, many people use the brakes to slow down. In fact, it is better to control the speed through the accelerator. For example, when you need to slow down at an intersection, many people will brake after reaching the intersection, which directly reduces the speed a lot. This is directly transmitted to the engine, reducing engine power.

In fact, we can predict in advance that when there is still some distance from the intersection, release the accelerator in advance. Once the accelerator is released, the speed of the car will decrease. As long as it does not affect the passage of the intersection, there is no need to step on the brakes, and less brakes. It will save fuel. After the intersection, accelerating, it will save fuel than direct braking.



The same is true for driving on the highway. Try to maintain a speed as much as possible. If there is a situation, make a response in advance to keep the speed stable. You can turn on the cruise control. If you are an old driver, you can reach it without cruise control. The effect of cruise control should not be underestimated. With years of accumulation, the difference in fuel consumption between people will come out.
