How to control the pressure of a cylinder separately

1. First, put the piston of the cylinder at the end of compression by twice adjustment, and then adjust the intake valve and exhaust valve of the cylinder.

2, secondly, according to the principle of two into three rows. That is, the intake valve of the second cylinder and the exhaust valve of the third cylinder must be completely closed at this time, and the adjustment can also be checked.

3. Finally, turn the flywheel 360 degrees to make the cylinder piston at the compression end point, and the other valves that have not been checked and adjusted are in the fully closed state. Therefore, all valves of the engine can be controlled by turning the crankshaft twice.
