    发动机电子控制节气门阀体的原理介绍
    2021-9-7 14:02:39

    电子控制节气门阀体(ElectronicThrottle Control Valve Assembly),简称为ETC,是现代发动机管理系统中进气控制管理系统的主要部件之一。它直接控制着发动机的进气总量,进而控制着发动机的转速和输出功率。

    Electronic throttle control valve assembly (etc) is one of the main components of intake control management system in modern engine management system. It directly controls the total intake of the engine, and then controls the engine speed and output power.

    电子控制节气门阀体总成是在发动机管理系统初期的机械式控制式节气门阀体的基础上设计发展出来的新产品。

    Electronic control throttle body assembly is a new product designed and developed on the basis of mechanical control throttle body in the early stage of engine management system.

    电子控制节气门阀体取消了机械控制式节气门阀体总成的机械操纵控制机构,即原有的节气门控制拉线(拉索)凸轮机构、怠速空气控制阀 (ISC或称为怠速电机,有些车型则采用的步进电机)和简单的节气门位置传感器(TPS)等重要部件;增加了驱动电机(或称为执行电机)、齿轮驱动机构、必要的机械传动元件和功能与可靠性更加强壮的特种节气门阀体位置传感器(主副节气门位置传感器,大部分车型又称为节气门传感器1与节气门传感器2)。


    The electronically controlled throttle valve body cancels the mechanical control mechanism of the mechanically controlled throttle valve body assembly, that is, the original throttle control cable (cable) cam mechanism, idle air control valve (ISC or idle motor, stepper motor used in some models) and simple throttle position sensor (TPS); Drive motor (or actuator motor), gear drive mechanism, necessary mechanical transmission elements and special throttle body position sensor with stronger function and reliability (main and auxiliary throttle position sensor, also known as throttle sensor 1 and throttle sensor 2 in most models) are added.

    电子控制节气门阀体总成的应用一定需要采用具有ETC系统驱动功能的专用发动机电子控制模块(ECM)硬件。同时,由于取消了机械式节气门阀体的机械式控制拉线机构,ETC还将需要配置有霍耳式加速踏板控制机构总成。

    The application of electronic control throttle body assembly must use special engine electronic control module (ECM) hardware with etc system driving function. At the same time, due to the cancellation of the mechanical control cable mechanism of the mechanical throttle body, etc will also need to be equipped with a hall accelerator pedal control mechanism assembly.

    电子控制节气门阀体总成的节气门开度大小由ECM根据驾驶人员控制的加速踏板控制输入信号,以及其他车辆输入的各种传感器输入信号,计算出车辆在该时刻和该状态下所需要的发动机输出功率并据此控制发动机的燃料供给(喷射)量,根据反馈信号修正控制参数,保证发动机工作在最佳控制状态。

    The throttle opening of the electronically controlled throttle valve body assembly is calculated by the ECM according to the accelerator pedal control input signal controlled by the driver and various sensor input signals input by other vehicles, and the engine output power required by the vehicle at this time and state is controlled accordingly, and the control parameters are corrected according to the feedback signal, Ensure that the engine works in the best control state.
