What is the working principle of electronic throttle?

Cars have become an essential tool for everyone to travel. Of course, automobile knowledge is essential. In order to make it easier for everyone to understand this knowledge, today I will tell you about the principle of electronic throttle. Interested friends can learn about it, which may be helpful to you. The electronic throttle changes the opening of the throttle through voltage change according to the pedal force of the driver. Vehicles using electronic throttle can adjust fuel consumption more accurately.

1. The biggest advantage of the electronic throttle control system is that it can achieve the best torque output in the whole range of the engine.

2. Adjust the throttle opening accurately. The electronic control unit first judges and processes various working condition information and sensor signals, then calculates the optimal throttle opening, and then adjusts the throttle to the corresponding throttle opening by driving the motor.

3. Improve the emission performance of the engine. Accurately adjust the air-fuel ratio under various working conditions to make the combustion more complete and reduce emissions. When idling, the throttle valve keeps a small opening to stabilize combustion, improve the rationality of fuel and further adjust emissions.

4. It has high driving reliability. Electronic throttle control system adopts sensor redundancy design. From the adjustment point of view, one sensor can make the system rotate normally, but the redundant design can make two sensors check each other, and when one sensor has problems, it can be identified immediately, which greatly increases the reliability of the system and ensures the safety factor of driving.

You can choose different working modes. Drivers can choose different working modes through the mode switch according to different driving needs. There are generally three modes: normal mode, power mode and snow mode. The difference is that the response speed of the accelerator to the accelerator pedal is different.

6. Height compensation can be obtained. At high altitude, the atmospheric pressure decreases, the air is thin, and the oxygen content decreases, which affects the output power of the engine. At this time, the electronic throttle control system can compensate the throttle opening according to the functional relationship between atmospheric pressure and altitude, and ensure that the relationship between engine output power and accelerator pedal position remains stable.
