I don't know if the coach will shout next to you when you learn to drive: "Step on the accelerator, quickly give oil", many car owners subconsciously feel that stepping on the accelerator is equivalent to giving oil. So can stepping on the accelerator really directly control the amount of fuel injection? This is not the case.
As we all know, the accelerator pedal is also called the accelerator pedal, and you can accelerate forward as soon as you step on the car, but the accelerator pedal has little to do with oil. When we press the gas pedal, it controls more the amount of air intake to the engine than the amount of fuel injected. When we slam down on the accelerator, the throttle opens up to the maximum, and the engine draws in more air as a result.
The real control of the amount of fuel injection is actually the engine control unit, which is what we call the ECU. It is equivalent to the intelligent brain of the car, which will control the amount of fuel injection according to our driving situation, so as to achieve the best air-fuel mixing ratio. Simply put, stepping on the accelerator is actually to increase the amount of air intake, and after the amount of air intake increases, the engine computer will control the increase in the amount of fuel injection when we request it, so as to achieve the purpose of acceleration.
After talking about whether stepping on the accelerator controls the amount of fuel injection, the next Xiaobian will talk to you about whether stepping on the accelerator can clean up carbon deposits. What we usually call carbon deposits is actually a mixture accumulated on the engine valves, combustion chambers and intake pipes, and carbon deposits will be produced when the engine itself is not fully burned or the oil is too inferior. When there is too much carbon deposit, it will not only lead to a decrease in engine power, an increase in fuel consumption, but also lead to a difficult cold start of the car, and so on.
So can Big Foot Bang really clean up carbon deposits? The answer is no. What we usually call the big foot stepping on the accelerator can clean up carbon deposits is in the case of high speed and high speed, and the air flow into the engine is very large, so it can play a role in washing away carbon deposits. But if your big foot steps on the accelerator is to step on the accelerator deeply, then release, then step on the accelerator, and then release again, which will not only consume fuel but even make carbon deposits worse.
To really clean up carbon deposits, we can remove the throttle, fuel injector and three-way catalytic converter to clean it, so that the cleaning is relatively clean. However, the disassembly of the fuel injector and the three-way catalytic converter is more complicated, and it may be difficult to install it back after you remove it, so Xiaobian recommends that you go to the repair shop to clean it. If you don't want to remove it for cleaning, you can also use fuel treasure to clean up carbon deposits. As long as we pour it into the tank when refueling, it will rush the carbon deposits into the combustion chamber and burn them along with the cycle.
In addition to learning the correct way to clean up carbon deposits, we must also learn to prevent the production of carbon deposits. The first point is to try to choose a regular gas station and add better quality oil, because the quality of gasoline has a relatively large impact on carbon deposits. The second point is to maintain good driving habits, avoid long idle driving, high gear and low speed driving, and so on.
In general, for car carbon deposits, we must detect and deal with them early to avoid affecting the car.
