What is the idling jitter of Volkswagen EA2 1 1 engine?

In this case, it is likely that the engine is out of order. Generally, a car with normal maintenance and extremely lubricated oil will not happen. It may also be because the engine has serious carbon deposition, which leads to jitter. You'd better send the car for maintenance. An engine is a machine that converts other forms of energy into mechanical energy, and a 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 adopt water cooling system. Million car purchase subsidy
