转速传感器的作用是：

　　1、发动机转速传感器又叫曲轴位置传感器，是电喷发动机控制系统中重要的传感器之一。发动机转速传感器的作用是检测发动机转速，可以确定曲轴的位置，检测活塞上止点信号和曲轴转角信号，并将检测的信号传送至ECU，用于控制点火时刻和喷油正时;PR6423/003-110+CON021 PR6424/000-131+CON031 PR6426/000-010+CON021 PR9376/010-011 PR6423/010-010+CON021 PR6426/010-010+CON021/916-160 PR6423/000-101-CN2、发动机转速传感器与凸轮轴位置传感器的结构和工作原理基本相同，相互协作，才能确保发动机正常工作。通常安装在一起，一般在分电器内，安装在变速箱离合器壳体上，在曲轴前端或曲轴后端，使用脉冲信号式转速传感器测量发动机转速。一些则安装在曲轴前端、凹轮轴前端或飞轮上，具体安装位置与发动机转速传感器的类型有关;

　　3、发动机转速传感器按传感器产生信号的原理可分为磁感应式、光电式和霍尔式3种类型。电磁感应式转速传感器分为2线制或3线制，而常见的霍尔式转速传感器是3线制的。其中的2线分别是电源线和交流信号线，3线的第3条线是交流信号屏蔽线，与搭铁连接。转速传感器工作原理：

The function of the speed sensor is to:

1. The engine speed sensor, also known as the crankshaft position sensor, is one of the most important sensors in the electronic fuel injection engine control system. The function of the engine speed sensor is to detect the engine speed, which can determine the position of the crankshaft, detect the top dead center signal of the piston and the crankshaft angle signal, and transmit the detected signal to the ECU for controlling the ignition timing and fuel injection timing; PR6423/003-110+CON021 PR6424/000-131+CON031 PR6426/000-010+CON021 PR9376/010-011 PR6423/010-010+CON021 PR6426/010-010+CON021/916-160 PR6423/000-101-CN2, the structure and working principle of the engine speed sensor and camshaft position sensor are basically the same, and mutual cooperation is necessary to ensure the normal operation of the engine. It is usually installed together, usually in the Distributor, and on the transmission clutch housing. At the front end or rear end of the crankshaft, the pulse signal speed sensor is used to measure the engine speed. Some are installed on the front end of the crankshaft, the front end of the concave wheel shaft, or the flywheel, and the specific installation position depends on the type of engine speed sensor;

3. Engine speed sensors can be divided into three types based on the principle of signal generation: magnetic induction, photoelectric, and Hall type. Electromagnetic induction speed sensors are divided into 2-wire or 3-wire systems, while the common Hall type speed sensors are 3-wire systems. The two wires are the power line and the AC signal line, while the third wire of the three wires is the AC signal shielding wire, which is connected to the ground. Operating principle of speed sensor:

When measuring the speed of mechanical equipment, the metal gears, racks, and other moving parts of the measured machinery will pass through the front end of the sensor, causing corresponding changes in the magnetic field. When the moving parts pass through the area where the magnetic field lines generated by the Hall element are relatively scattered, the magnetic field is relatively weak, When passing through areas that generate magnetic field lines, the magnetic field is relatively strong;
