Recently I have heard many car enthusiasts asking how electronic throttle body works, so let me answer that for you.
Electronic throttle control system (ETC) is born along with the concept of electronic wire control. The electronic throttle body is an important control component of an automobile engine. It replaces the traditional mechanical connection between the gas pedal and throttle body, and connects the gas pedal to the throttle through wires, which can improve the control of the engine and avoid the bad consequences caused by improper operation of the gas pedal by the driver. It can precisely control the throttle opening in real time by adding corresponding sensors and electronic control units. It can realize engine torque control and precise air-fuel ratio control, which can help improve the driving force, stability and economy of the car, and can effectively reduce emission pollution.
1, The automobile electronic throttle technology (ETC) is accompanied by the automobile electronic drive concept (Drive-by-Wire) and the birth of. Electronic throttle body (ETC) is an important control component of the automobile engine.
2, It replaces the traditional gas pedal and throttle body between the mechanical connection, through the wire so that the accelerator pedal and throttle to establish contact, can improve engine control, to avoid improper operation of the accelerator pedal by the motorist to produce adverse consequences. It increases the corresponding sensor and electronic control unit, real-time precise control of the throttle opening degree.
3, Electronic throttle body (electronic throttle valve) is an important control component of the car engine. By the engine, speed sensor, throttle and other components, the use of electronic throttle control system, can make the throttle opening degree to get precise control.
4, The basic structure of the electronic throttle system has the following components:
I. engine
II. speed sensor
III. throttle position sensor
IV. throttle actuator
V. throttle body
VI. accelerator pedal position sensor
VII. speed sensor
VIII. transmission
IX. accelerator pedal
X. throttle electronic control unit (ECU)
Potentiometer is composed of two reverse signal meter, one reflecting the forward opening position of the throttle, the other reflecting the reverse opening position of the throttle, compare the signal values of the two signal meters can check each other’s work status, as a basis for determining whether there is a failure.
