What is the adjustment method of the valve of a single cylinder gasoline engine?

Valve adjustment method of single-cylinder gasoline engine in Pacific Auto Network: 1, first remove the spark plug; 2. Remove the pull plate. 3. Take out the tool for testing the valve clearance; 4. Loosen the nuts of the upper and lower rocker arms; 5. Put a feeler gauge of 10 mm under the rocker arm; 6. Tighten the rocker nut and remove the feeler gauge to complete the operation.

1. When adjusting, loosen the lock nut and adjusting screw first, and insert the valve clearance with the specified value and the valve plug with the same thickness into the gap between the valve foot and the rocker arm;

2. Pull the plug back and forth by turning the adjusting screw. When the plug feels slight resistance, check and tighten the lock nut. If the gap changes, it needs to be readjusted.

3. Generally speaking, the adjustment methods of valve clearance mainly include cylinder-by-cylinder adjustment method and secondary adjustment method.

Single cylinder diesel engine, that is, diesel engine with only one cylinder when classified according to the number of cylinders. Single-cylinder diesel engines are mainly used in agricultural machinery, construction machinery, automobile industry, marine machinery, electric power industry and other fields. Every working cycle of a single-cylinder diesel engine has to go through four processes: intake, compression, work and exhaust. Diesel engine is an internal combustion engine that uses diesel as fuel and converts the heat energy released by fuel combustion into electrical energy or mechanical energy. Single-cylinder diesel engines have two strokes and four strokes, and their mechanisms are basically the same. The main difference lies in the structure of valve train. In a working cycle, only one stroke does work, and the other three strokes are auxiliary strokes that create conditions for the work stroke. Therefore, the work of single cylinder diesel engine is unstable.
