What is the valve clearance of diesel engine?

The valve clearance parameters of diesel engine are as follows:-Valve clearance: 0.25-0.30mm- Exhaust valve clearance: 0.30-0.35mm Many valve clearance parameters are preferably between 0. 15-0.4mm and adjusted between 0.2-0.35 mm We can make the best decision according to the provided data and our own experience and current development trend. The purpose of setting valve clearance is to ensure the normal operation of the valve train of internal combustion engine. Because the valve train is in a high-speed state and the temperature is high, the tappet and other parts will be extended due to heating, resulting in the valve not being closed and air leakage. In order to avoid this phenomenon, when designing the valve train, there should be a certain gap between the rod end of the intake and exhaust valve and the adjusting screw on the tappet (or rocker arm), which is called valve clearance.
