What Is The Function Of The Engine Valve

The function of the valve is to open the intake valve, and the combustible mixture enters the combustion chamber. The two valves are closed at the same time, ignite combustion, open the exhaust valve, and exhaust the waste gas. The most common faults of valves are carbon deposits and gumming. After carbon deposition and cementation, the valve is not closed tightly and the cylinder pressure is reduced, resulting in insufficient engine power. If the valve is stuck, the cylinder head will also be jacked. The top of the valve can be cleaned with fuel additives (when the mixture enters). In addition, each valve has an oil seal. If the oil seal is damaged, the oil will flow into the combustion chamber, causing oil burning.
