The role of the exhaust valve is to discharge the burned exhaust gas and dissipate heat. The function of the valve is to be responsible for inputting air into the engine and discharging the exhaust gas after combustion. From the structure of the engine, it is divided into intake valve and exhaust valve.
Symptoms of valve damage are as follows:
1. It will affect the working efficiency of the engine, and the power of the car will be reduced;
2. Abnormal noise from the shovel, the engine will experience unstable idling or poor acceleration during operation, and the overtaking performance will also be reduced. Air leakage or increased carbon deposits;
3.A broken valve will cause the cylinder to work unstable. The unstable cylinder will cause the engine to vibrate, the engine will work weakly, and it will also cause the exhaust pipe to be blocked. In severe cases, it will also cause black smoke.
Intake and exhaust valve structure:
In order to improve the efficiency of intake and exhaust, multi-valve technology is often used now. It is common that each cylinder is equipped with 4 valves (there is also a single-cylinder design with 3 or 5 valves), and 4 cylinders have a total of 16 valves. We are in the car information The "16V" often seen on the Internet means that the engine has 16 valves in total. This multi-valve structure is easy to form a compact combustion chamber, and the fuel injector is arranged in the center, which can make the fuel-air mixture burn more quickly and more evenly, and the weight and opening of each valve are appropriately reduced, so that the valve can be opened or closed. faster.
