How to Adjust the Valve of Single Cylinder Diesel Engine

Adjustment method: Open the valve cover, unscrew the adjusting nut on the rocker arm, turn the adjusting screw, and hold the valve ejector pin with the thumb and fingers of your hand for rotation. When the resistance is small, even after adjustment, tighten the retaining nut. Don't try too much or too little resistance. The same method is also applicable to other valves. Every working cycle of a single-cylinder diesel engine has to go through four processes: intake, compression, work and exhaust. In a working cycle, only one stroke is doing work, and the other three strokes are auxiliary strokes that create conditions for doing work.

Extended data

Working principle of single-cylinder diesel engine: Single-cylinder diesel engine includes two-stroke diesel engine and four-stroke diesel engine, and its mechanism is basically the same, the main difference is the structure of valve train. The development of single-cylinder diesel engine still depends on the innovation of science and technology, and constantly uses new technology to improve the existing shortcomings and deficiencies of single-cylinder diesel engine and expand its application scope. For example, it is equipped with oil limiting device and emission control device to meet the needs of motor vehicle use and environmental protection.
