Electronic throttle and (car cable) Pull throttle difference?
We know that the control can control the throttle opening degree of the flow of combustible gas mixture to change engine speed and power, to meet the needs of cars. Conventional engine throttle control mechanism is activated by cable (soft steel), or rod, one end of the coupling the accelerator pedal (accelerator pedal), the other end of the coupling plate and the throttle interlocking work. But this traditional throttle application areas is restricted and the lack of accuracy, in a rapidly changing situation, the development of automotive electronics, an electronic throttle (EGAS) came into being.
Compared with the throttle cable, electronic throttle obvious point is that you can use the harness (wire) to replace the cable or rod, the throttle side mounted a miniature electric motors, electric motor to drive the throttle opening. So-called "wire driving", with a wire instead of the original mechanical transmission. But this is only the surface of things electronic throttle, its substance and effect only way to resolve connection instead of using it is not enough.
Electronic throttle control system consists of the accelerator pedal, the pedal position sensor, ECU (electronic control unit), the data bus, servo motor and throttle actuator components. Displacement sensor is mounted within the accelerator pedal, monitoring the position of the accelerator pedal. (Cable car) to the accelerator pedal when the monitored height position has changed, this information will be instantly sent to ECU, ECU for the information and other data from the information system, arithmetic processing, calculates a control signal through the line to the servo motor relay, servo motor drives the throttle actuator, the data bus is responsible for the system ECU and other communications between the ECU. As electronic throttle system to adjust the throttle through the ECU, so you can set a variety of electronic throttle system features to improve driving safety and comfort, the most common is the ASR (traction control system) and speed control system (cruise control ).
