Volkswagen EA2 1 1 Idle Jitter

Causes and solutions of idling jitter of Volkswagen EA2 1 1 engine;

1. Fuel system failure, such as excessive colloidal carbon deposition in the nozzle, which leads to the nozzle not being closed tightly or blocked; It is recommended to clean the colloidal carbon deposit in the fuel injector.

2. The engine throttle carbon deposit phenomenon is too serious; It is recommended to clean the carbon deposit on the engine throttle.

3. Engine mechanical failure, such as uneven pressure in each cylinder; It is recommended to go to a professional maintenance station for inspection and maintenance.

4, air intake system failure, such as air intake pipe leakage. It is recommended to replace the intake pipe at a professional maintenance station.

An engine is a machine that converts other forms of energy into mechanical energy. Gasoline engine is a power device that converts chemical energy into mechanical energy. The cooling system of the engine ensures that the engine works at the most suitable temperature by absorbing the heat of the parts. According to the different cooling media, the cooling system can be divided into air cooling and water cooling. Air cooling directly radiates the heat of engine parts to the atmosphere for cooling, while water cooling transfers the heat to cooling water and then radiates it to the atmosphere. The cooling effect of water-cooled engine is better. At present, most engines are cooled by water coolers. Million car purchase subsidy
