What is the working principle of electronic throttle system?

Higher. Throttle is a vital component in the EFI automobile engine system, which is located between the air filter and the engine block and can control the intake air of the engine. Drivers can choose different working modes through the mode switch according to their driving needs, including normal mode, power mode and snow mode. The response speed of the accelerator to the accelerator pedal will be different in different working modes. The electronic throttle control system adopts redundant sensor design to improve the reliability of the system. The electronic throttle control system has the following advantages: 1, which can achieve the best torque output in the whole range of the engine; 2. Correctly control the throttle opening to make the combustion more complete and reduce the generation of waste gas; 3, it can improve the emission performance of the engine, keep a very small opening angle at idle speed, make the combustion more stable, reduce fuel consumption and further inhibit emissions; 4. It has high vehicle running reliability.
