With the continuous rise in oil prices, many car owners often complain that "oil prices have risen again, and the accelerator pedal is not daring to step on it!" So will the severity of stepping on the accelerator really have an impact on the fuel consumption of the car? How big is the impact? Today, Xiaobian will give you a good science popularization for these two problems.
As we all know, the accelerator pedal is also called the accelerator pedal, and the car can accelerate forward as soon as you step on it. The severity of stepping on the accelerator does have a certain impact on the fuel consumption of the car. Especially when we step on the accelerator and press the accelerator to the end, the fuel consumption of the car will be much higher than that of stepping on the accelerator lightly, which may be about twice as high. Many people will ask: the throttle is heavier and the acceleration is faster, which means that it can reach the destination in less time. Pressing the accelerator takes longer, so shouldn't the car consume about the same amount of fuel?
From the perspective of conservation of energy, this statement seems to make a lot of sense. But not every drop of oil is used to make the wheels of the car roll forward, now few engines can achieve more than 60% thermal efficiency, that is to say, 60%-70% of the oil will be directly wasted in the engine, so in the case of a big foot throttle, the waste rate of gasoline will be higher, and the fuel consumption will be higher. In addition, in the case of complex road conditions, the difference in fuel consumption between stepping on the accelerator and stepping on the accelerator lightly may be more than two percent, and even three or four percent.
First of all, we should try to ensure that the accelerator is stable when we step on the accelerator, and do not step on the accelerator back and forth. Many car owners like to step on the accelerator slowly, if you feel that the speed is fast, a little pad the brake, then step on the accelerator, and then pad the brake. If the car engine fluctuates back and forth in this way, the combustion conditions will also deteriorate, and the fuel consumption of the car will naturally increase.
Secondly, we should pay attention to avoid stepping on the accelerator when stepping on the accelerator to accelerate sharply, many car owners enjoy the feeling of pushing back when accelerating, and feel that they have instantly become the god of autumn mountain cars. However, hard acceleration is more fuel-efficient than slow acceleration, and fuel consumption will increase by more than 30%. Therefore, you must not accelerate sharply in a hurry, which not only consumes fuel, but also accelerates the wear and tear of the engine.
If we want to save fuel when driving, in addition to learning to step on the accelerator, we must also learn to drive predictively and not to step on the brakes frequently. Some friends always keep a short distance from the car in front when driving, and from time to time they have to apply the brakes, and then accelerate to keep up with the car in front. And when encountering an intersection with a traffic light, do not step on the brakes in advance to slow down the speed, and only slam on the brakes to stop the car when you are almost at the intersection. In fact, frequent braking and slamming on the brakes will also increase fuel consumption, and the most important thing is that it is easy to cause traffic accidents, so we must try to avoid emergency braking.
In general, if you want to save fuel in your car, you must learn to step on the accelerator, and you must get rid of those bad driving Xi and take good care of your car.
