In what way can the fatigue strength of valve be improved?

The valve neck requires Ra up to 0.2, which requires high turning and polishing processing and is difficult to achieve or has low processing efficiency. The traditional polishing methods, such as grinding wheel polishing, fluid polishing and electrolytic polishing, have low processing efficiency and certain influence on the environment.

Analyze valve and valve seat Angle

Engine cylinder seal needs three places: piston, piston ring and cylinder seal; Sealing of cylinder pad; Seal of valve and valve seat.

The engine valve is a very important component. If it is small, it may leak in hot conditions

The so-called valve clearance refers to: when the engine is in a cold state, the valve transmission mechanism leaves a certain gap. To compensate the expansion of valve and transmission mechanism after heating.

What are VVT engine valves? Let's find out

It is according to the operation of the engine, adjust the intake (exhaust) amount, and valve opening and closing time, Angle. Make the amount of air into the best, improve the combustion efficiency.

Common failure of valve

We occasionally encounter the situation of engine valve rod bending in maintenance. This fault is mostly caused by the transmission belt of the valve mechanism jumping teeth or breaking, leading to the asynchronous operation of the piston and valve, which makes the piston up and down the valve collision, resulting in the valve rod bending and deformation. In the event of such a failure, it is generally necessary to replace the valve, and check whether the valve guide and piston connecting rod mechanism are abnormal.

Multi-valve engine

On January 29, 1886, Karl Benz, a German, installed his four-stroke single-cylinder fuel engine on a three-wheeled car and obtained the patent, and the world began to have a real automobile from this day.
