Why is the accelerator of automobile engine often dirty and how to solve it?

1. The main reason why the throttle is dirty and carbon deposit is that the airflow moves back and forth during the intake and exhaust of the engine during the working stroke, rather than just intake.

When the valves overlap, the inhaled air will also flow back to the air intake, resulting in the formation of carbon deposits.

2. In addition, the forced ventilation of the crankcase in front of the throttle valve will re-introduce the exhaust gas in the crankcase into the cylinder through the intake valve for combustion.

It also directly leads to dirty throttle.

3. Dirty throttle will cause excessive idle speed, weak acceleration and engine light alarm. The simple solution is to clean the throttle.
