What are the advantages of electronic throttle?

There are two kinds of throttles: traditional wire throttle and electronic throttle. The traditional engine throttle control mechanism works through steel wire (soft steel wire) or joystick, one end of which is connected with the throttle pedal and the other end is connected with the throttle linkage plate. The electronic throttle mainly controls the opening of the throttle and adjusts the air intake through the throttle position sensor according to the energy required by the engine. Advantages of electronic throttle: 1. Advantages: The biggest advantage of the electronic throttle control system is that it can achieve the best torque output of the engine in a full range; 2. The disadvantage is that the conventional PID control can not accurately set the feedback gain, which affects the control accuracy. 3. Correctly control the throttle opening. ECU first judges and processes various working condition information and sensor signals, then calculates the optimal throttle opening, and drives the motor to control the throttle at the appropriate throttle opening angle. And the emission performance of the engine is improved. ETC system accurately controls the air-fuel ratio under various working conditions, which makes the combustion more complete and reduces the generation of waste gas. In the idle state, the throttle valve is kept at a small opening, which makes the combustion stable, the fuel consumption is improved and the emission is further suppressed.
