Step on the gas pedal without oil supply, and turn off and restart directly. What's going on here?
It may be an engine fault, because one of the injectors is blocked, so it doesn't matter if the speed is low. The throttle is large, the rotation speed is high, the oil ejected is not enough, the pressure generated by combustion is not enough, and the work done is not enough. When the gear is high, the traction is already very small and it is easy to stall. Gas path oil path problem. The throttle valve is dirty. When accelerating, the throttle opening is not enough or the reaction is lagging behind, too much carbon is deposited, and the fuel injection is abnormal. It is necessary to clean the throttle and fuel injectors. In addition, check the oil pump pressure. If the oil pump depressurizes or the air filter is blocked, the oil supply will be insufficient.
If the engine is turned off, even if the ignition switch is in the "on" position, the driver only opens the throttle valve and gives the throttle opening signal, but without the air flow signal and engine speed signal, the fuel injector will not start to inject fuel. Therefore, for the current electronic fuel injection system, in the case of engine flameout, the injector will not inject fuel by stepping on the accelerator, and there will be no gasoline stepping into the cylinder. The old driver's worry is unnecessary.
There are several reasons for this. Excessive carbon deposition on the throttle of a vehicle will cause the throttle to be stuck or damaged, which will lead to the throttle not being filled with oil. There is something wrong with the accelerator pedal of the car, which can't work normally. If the throttle sensor is damaged, it will make the throttle unable to refuel and need to be re-ignited.
If the throttle cannot be cleaned normally for a long time, the inner wall of the throttle will be greasy, and it will solidify after a long period of high temperature, which will bring continuous resistance to the throttle motor, resulting in uncontrolled or unstable idle speed and slow response of the oil pedal, but just stop the car and switch it on and off several times. These problems are caused by dirty throttle, so regular cleaning is essential.
