How to adjust the idle speed of electronic throttle; There are several types of electronic throttles.

How to adjust the electronic throttle 1 idle speed? Generally, high-grade cars can be adjusted and matched by computer, and there is a screw on the door of low-grade cars that can be adjusted: first unscrew the throttle, adjust the screw to make the engine reach the lowest stable speed, and then put the screwdriver on the idle screw.

2. When the engine is about to stall, slowly unscrew the idle screw with a screwdriver to make the engine run stably and reach high speed, and then unscrew the throttle screw to minimize the engine speed from high speed.

3. Then unscrew the screw to increase the engine speed, and so on, until the throttle opening is minimum, and suddenly close the throttle.

Adjusting the idle speed of the above throttle will cause early wear and tear to the engine. It is not recommended for car owners to adjust themselves. Better go to the auto repair shop to adjust it!

Attachment: Basic Structure of Electronic Throttle

Engine, accelerator pedal position sensor, vehicle speed sensor, speed sensor, accelerator position sensor, accelerator actuator, accelerator, transmission, accelerator pedal and ECU.

Idle speed: refers to a working state, no-load operation, the engine only "outputs" and does not consume engine oil, that is, when the automobile gear is in neutral.

The influence of idle speed on driving;

1. Idle driving consumes a lot of fuel.

2. High idle speed can reduce the emission of harmful tail gas.

3. When idling, insufficient fuel is easy to cause carbon deposition.

There are several types of electronic throttles.

Four kinds. There are four types of electronic throttles: electro-hydraulic type, linear electromagnet type, stepping motor type and DC servo motor type. However, electro-hydraulic type and stepping motor type are rarely used in automobiles because of their low control accuracy, and linear electromagnetic type is rarely used in automobiles because of its large power consumption. DC servo motor type overcomes the above two situations well, so it is widely used in automobiles.

In addition, the throttle valve also needs to be replaced regularly, and the length of time mainly depends on factors such as the quality of air filter, the quality of engine oil and the road conditions of vehicles. (Photo/Text/Photo: Ask and Answer Animals) @20 19
