Why valves bend, on which cars this failure is possible, and how to prevent it. Every motorist, for general development, should know how many cylinders are in his car, as well as how many valves. In modern engines, there are usually from 8 to 16 valves (two or four per cylinder), there are power plants (eight or twelve-cylinder), which have a number of valves - from 24 to 32. About valves, we can say that this is part of the gas distribution mechanism of the car GRM. With this most important work, there would be no exhaust gas release, and compression in the cylinders would not be created during injection and ignition of fuel. The same valve cannot perform these functions, and therefore each cylinder is equipped with two types of valves - intake valves, which supply air to the combustion chamber, and exhaust valves, which squeeze out the combustion products of the fuel-air mixture from this chamber. In the structure of the valve, two parts are distinguished: a plate and a rod. It is the valve stem that is hit when one of the elements of the valve timing mechanism fails. Subscribe to my channel.
