The throttle valve is the core control component of the engine intake system, which controls the power output of the engine by adjusting the intake air volume, directly affecting the acceleration performance, fuel economy, and emission level of the vehicle.
Working principle
Basic functions
The throttle valve is located between the air filter and the intake manifold, and controls the air flow into the cylinder by changing its opening. When the driver steps on the accelerator pedal, the throttle opening increases, the intake volume increases, and the engine speed increases; Otherwise, reduce the rotational speed.
The Evolution of Electronic Throttle (ETC)
Traditional cable type throttle valve: directly connected to the accelerator pedal through a mechanical cable, with fast response but low accuracy, and prone to unstable idle due to wear and tear.
Electronic Throttle (ETC): The ECU (Engine Control Unit) precisely controls the throttle opening through the motor based on signals such as accelerator pedal position, vehicle speed, and engine operating conditions, achieving more accurate air-fuel ratio control.Collaboration with the intake system
Changes in throttle opening can cause fluctuations in intake manifold pressure, which requires coordination with sensors such as the intake pressure sensor (MAP) and air flow meter (MAF) to ensure accurate fuel injection calculation by the ECU.
