What are the advantages of electronic throttle?

The advantages of electronic throttle are as follows:

1. can achieve the best torque output of the engine in a full range.

2. Accurately control the throttle opening. ECU first judges and processes various working condition information and sensor signals, then calculates the optimal throttle opening, and then the driving motor controls the throttle to reach the corresponding throttle opening.

3. Improve the emission performance of the engine. ETC system accurately controls the air-fuel ratio under various working conditions, which makes the combustion more complete and reduces the generation of exhaust gas; When idling, the throttle valve is kept at the minimum opening to stabilize combustion, improve fuel economy and further control emissions.

4. It has high vehicle running reliability. Electronic throttle control system adopts sensor redundancy design. From the control point of view, one sensor can make the system run normally, but the redundant design can make two sensors detect each other, and when one sensor fails, it can be identified in time, which greatly increases the reliability of the system and ensures the safety 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 usually 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 drops, the air is thin, and the oxygen content drops, which leads to the decrease of engine output power. At this time, the electronic throttle control system can compensate the throttle opening according to the functional relationship between atmospheric pressure and altitude, so as to ensure that the relationship between engine output power and accelerator pedal position remains stable.
