How to adjust the Jetta automatic electronic throttle?
When the driver steps on the accelerator when he needs to accelerate, the pedal position sensor will transmit the sensed signal to the ECU through the cable. After analysis and judgment, ECU will send instructions to the driving motor, and the driving motor will control the opening of the throttle valve to adjust the flow of combustible mixture. Under heavy load, the throttle opening is large, and a large amount of combustible mixture enters the cylinder. If the cable throttle is used, the throttle opening can only be controlled by stepping on the depth of the accelerator pedal. It is difficult to adjust the throttle opening to reach the theoretical air-fuel ratio, but the electronic throttle can analyze and compare all kinds of data collected by sensors through ECU, send out instructions to make the throttle actuator act and adjust the throttle to the optimal position, so as to reach the theoretical air-fuel ratio 14.7: 1 under different loads and working conditions, and make the fuel burn fully.
Electronic throttle control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator. The displacement sensor is installed in the accelerator pedal to monitor the position of the accelerator pedal at any time. When it is detected that the height position of the accelerator pedal changes, the information will be sent to the ECU instantly. The ECU will calculate and process these information and data information from other systems to calculate a control signal, which will be sent to the servo motor relay through the line. The servo motor drives the accelerator actuator, and the data bus is responsible for the communication between the system ECU and other ECU. Because the electronic throttle system adjusts the throttle through ECU, various functions can be set to improve driving safety and comfort, among which ASR (traction control system) and speed control system (cruise control) are the most common.
