03F133062B Throttle valve is a controllable valve for control of air into the engine. The air entering the intake pipe is mixed with gasoline to form a combustible mixture, which will then burn and do work. Connected to an air filter at the upper end and to an engine cylinder at the lower end, the throttle valve is called “the throat” of the engine on a car.
1. Basic function
The throttle valve controls the amount of air sucked by the engine, and consequently provides sufficient air required for combustion in the engine.
2. Further function
The opening degree of the throttle valve is reflective of the working load of the engine. The larger the opening angle of the throttle valve, the higher load of the engine (and the higher torque at the same driving speed or the higher driving speed at the same torque). The throttle valve generally consists of accelerator pedal, throttle valve pull wire, throttle valve opening degree sensor, and throttle butterfly valve.
In the engine intake air control with the throttle valve, ECU signals are generated depending on the opening angle of the throttle valve. With longer conduction time of the triode on the ECU fuel injector, the fuel injector will be opened for an extended period of time and supply more fuel. The throttle valve serves the main purpose of supplying engine load signals to ECU so that a basic fuel injection time can be set.
