For example:

Adjustment of valve clearance of four-cylinder engine;

Adjust the valve clearance according to the ignition sequence of 1-3-4-2. The order is as follows:

1. Adjust the first cylinder to the top dead center, and adjust the intake valve and exhaust valve of 1 cylinder, the exhaust valve of cylinder 3, and the intake valves of cylinders 4 and 2.

2. Then rotate the crankshaft 360 degrees, make the piston of cylinder 4 reach the top dead center, and adjust the intake and exhaust valves of cylinder 4, cylinder 2, 1 cylinder and cylinder 3.

Adjustment of valve clearance of V8 engine;

Adjust the valve clearance according to the ignition sequence of 1-5-4-2-6-3-7-8. The order is as follows:
