What Causes Knock in Vehicle?
Although internal combustion engines operate according to two different fuel types, diesel and gasoline, their working principles are basically the same. In the combustion chamber, where chemical energy is converted into motion energy, the fuel is burned as a result of certain stages and the resulting energy moves the vehicle. The combustion process in gasoline engines consists of stages in the form of suction, compression, combustion and exhaust. The compressed air, fuel mixture, and spark plugs are ignited by the cylinder and the resulting pressure force turns the crank arm. There may be more than one reason for knocking situations in vehicles. In particular, the octane ratio in gasoline can cause the fuel to self-ignite with the heat generated when it is compressed. In this way, before the cylinder can reach its upper position, it wants to create a rotating effect on the crank arm again. This causes knocking. Another reason is the delays that may occur in spark plug igni
