Engine valve

The engine valve is one of the important parts of the engine, and its function is to control the switch of the intake and exhaust valves. Its length is generally determined according to the design and requirements of the engine, and is usually determined by the engine manufacturer according to the actual situation.

The length of the engine valve directly affects the opening and closing time of the valve and the valve lift, thereby affecting the intake and exhaust effects and the performance of the engine. If the valve length is inappropriate, the valve may not be completely closed or closed tightly, affecting the sealing of the valve, resulting in poor intake and exhaust, and affecting the working efficiency and combustion effect of the engine.

When determining the length of the engine valve, it is necessary to consider the material, shape, friction coefficient of the valve, engine speed, power and other factors. Generally speaking, an engine with a higher speed needs a longer valve length to ensure that the valve can be completely closed and opened when rotating at a high speed, so as to ensure the sealing of the combustion chamber and the normal operation of the valve.

In short, the length of the engine valve is determined by the engine manufacturer according to the actual situation, and its reasonable design and adjustment can effectively improve the working efficiency and performance of the engine.
