Description

Technical Field

[0001] The utility model relates to the technical field of valve installation, in particular to an engine valve installation mechanism. Background Art

[0002] The valves do play a very important role in internal combustion engines, especially in four-stroke engines. The intake valve is the component responsible for introducing air (usually together with a fuel mixture) into the engine. The intake valve opens during the intake stroke of the cylinder, allowing outside air to enter the cylinder. This air is usually mixed with the injected fuel to form a combustible mixture. The exhaust valve is the component that discharges the burned exhaust gas from the cylinder. During the exhaust stroke of the cylinder, the exhaust valve opens to allow the burned fuel residue and exhaust gas to be discharged. These exhaust gases contain carbon dioxide, nitrogen, water vapor and other combustion products. The opening of the exhaust valve not only discharges the exhaust gas, but also allows the engine to cool down after combustion. The exhausted exhaust gas takes away some heat, which helps to control the engine temperature and maintain stable operation.
