How to improve the engine speed

For gasoline engines, the throttle valve controls the opening of the throttle valve, thus affecting the intake of the engine. After stepping on the accelerator, fresh air enters, and the fuel injection quantity controlled by ECU also increases, so the force generated by combustion also increases, driving the engine to run faster.

Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
