The way the accelerator of the car is broken.

According to Bian Xiao, many friends don't know much about cars. Some time ago, a friend asked Bian Xiao about the broken throttle. The following small series will share our views. It may be helpful for friends who want to know.

After the throttle is broken, there will be unstable idle speed, no idle speed, and it is difficult to accelerate at the start.

The throttle valve regulates the air intake of the engine, and the accelerator pedal is responsible for regulating the throttle valve without regulating the fuel injection quantity. After the driver steps on the accelerator pedal, the ecu receives the signal, and then the ecu adjusts the accelerator opening. When the throttle opening becomes larger, the fuel injection quantity will also increase accordingly.

When idling, the throttle will have an idle valve to adjust the amount of air entering the engine. If the throttle is damaged, it will affect the unstable idle speed or even no idle speed.

Some cars are easy to stall when idling, and only when the driver keeps stepping on the accelerator will they stall, so this is the phenomenon of not idling.

Severe carbon deposition in the throttle will also affect idle instability. Clean up the carbon deposit after such problems occur. When cleaning the carbon deposit, first remove the throttle and then clean it with professional cleaning agent. After cleaning, wipe with a special cloth. After cleaning up the carbon deposit and putting it back, it is best to reconfigure the ecu, otherwise it may affect the fuel consumption.

When using a car at ordinary times, you must not add inferior gasoline, which will aggravate the carbon deposition on the throttle or in the cylinder.

Some in-cylinder direct injection engines are very prone to carbon deposition. It is recommended that small partners who use in-cylinder direct injection engines clean up carbon deposits every 20,000 kilometers. Walnut sand cleaning method is very useful in cleaning up carbon deposits.
