ZH 1 1 15 single cylinder diesel engine control valve

Diesel engine valve has large intake and small exhaust. When adjusting the valve of a single-cylinder diesel engine, you can turn the flywheel and unscrew the high-pressure fuel pipe connector of the injector. When the diesel oil in the high-pressure oil pipe is driven by the flywheel, it is the compression top dead center. This is to stop the flywheel and adjust the intake and exhaust valves. It is best to use a hot car to adjust the valve. Methods: Open the valve cover, loosen the adjusting nut on the rocker arm and turn the adjusting screw. At this time, hold the valve ejector pin with your thumb and forefinger, and tighten the retaining nut when you feel a little resistance. Don't try too much or too little resistance, try several times. Another valve is the same way. This is the actual operation. Theoretically, the intake valve clearance is 0.25-0.3, and the exhaust valve clearance is slightly larger, 0.3-0.35 mm The specific value can be measured with a feeler gauge.
