Unlocking the Relationship between Idle Motor and Throttle Position Sensor

What is idle motor?

 

Idle motor is a component to control the idle speed of motor vehicles. The engine is called idling when it is empty.

 

The role is:

 

During idling, according to the engine temperature and load size, the cross -sectional area of ​​the idle airway is changed, so that the engine has the best idling speed under different conditions.

 

The idle motor is mainly used to bear the idle speed of the car. The purpose is to adjust the idle speed according to the engine load at the time of idle speed. The idle steaming motor is installed on the throttle valve body, and the engine controller is used to control the engine idle speed. When the engine speed deviates from idle speed, it will be adjusted by the solar term. Essence The throttle body has a bypassing airway, providing air when the engine is idle (when the throttle is closed). The pivot of the automatic idle motor stretches into the bypass airway. By adjusting the air flow, the engine controller uses the input signal of various sensors to use the pivot of the mobile unclear motor to enter and exit the bearing speed of the engine. When the ignition key turns to the open position, the automatic idle motor starts to work. This switching signal enters the ECU to perceive whether the engine is at idle. At the same time, the instant location of the motor is fed back to the ECU by the motor position sensor.

 

What is the throttle position sensor?

The throttle position sensor is one of the most important sensors in the automotive electronic control system. It is mainly used to measure the gas volume of the car engine knotting valve.

The main function of the throttle position sensor is to detect whether the engine is idle or load, whether it is accelerated or decelerated. It is essentially a variable resistor and several switches, which are installed on the solar terms. The rotation of the resistor is linked to the throttle, and it has two contacts: full contact and idle contact. When the throttle is at a idle position, the idle contact is closed to output idling work signals to the computer; when the throttle is in other positions, the idle contact is opened, and the output voltage signal compared to different angles of the throttle. The computer recognizes the load of the engine according to the signal voltage value; the increase and decrease rate of the signal voltage within a certain period of time is recognized whether it is accelerated or decelerating. Computers correct the amount of fuel injection based on these working conditions, or perform oil -breaking control

 

 

Sensors of idle motor and throttle positions are installed on the throttle. The solar terms are mainly divided into three components: execution agencies, throttle blades, and throttle position perceptuals. In terms of structure, there are two main types of solar terms, namely traditional pull -line and modern electronic firing gates.

 

The traditional engine throttle control agency depends on the tension (ie, the soft steel wire material) or the tie rod. One end is closely connected to the accelerator pedal, and the other end is connected to the linkage board of the throttle to achieve operating functions. The electronic ventilation door relies on the throttle position perceptual. According to the energy needs required by the engine, the opening angle of the throttle opening is accurately controlled, and then the air volume of entering the engine is adjusted.

 

The throttle is played in the car engine. The specific role is as follows:

 

1. The throttle door is a controllable valve that regulates the air entering the engine. When the air enters the air pipe, it will be mixed with gasoline (the mixed positions of different models may be different) to form a combustible mixed gas, and then participate in combustion and work, and provide power for vehicles with power Essence

 

2. In the modern motor vehicle engine system, the throttle is the core component. The above is connected to the air filter, and the bottom is connected to the engine cylinder, like the throat of the car engine, which is responsible for regulating the speed of the vehicle.

 

3. The degree of cleaning of the throttle is closely related to the flexibility of the acceleration of the car. The driver can control the opening level of the throttle by stepping on the acceleration pedal, thereby achieving the purpose of deceleration or acceleration.
