Does Yuchai single cylinder diesel engine have an effect on ignition?

Reasons why diesel engine is not easy to start in hot state;

1. The valve clearance is too small, and the cold start is easy, but there is no clearance leakage as the valve assembly heats up and expands; 2. The piston ring gap is too small, and the piston ring expands when the car is hot, which leads to an increase in resistance and difficulty in starting;

3. The oil supply time is too early, which causes the piston to burn out before the top dead center, which makes the piston bear strong back pressure and makes it difficult to start. The following is the solution: 1. Adjust the valve clearance; 2. Replace the qualified piston ring; 3. Delay the oil supply time by adding oil pump gasket, so as to adjust the oil supply time. Specifically, disassemble the high-pressure oil pipe and install it outside, slowly rotate the flywheel and observe the flywheel scale; You can also remove the cylinder head and observe the distance from the piston to the top to adjust the oil pump gasket.
