What is the method for adjusting engine valves?

[RobertDella]

Engine valve adjustment is performed as follows: 1. Based on the cylinder firing order, after confirming that a piston is at the top dead center of the compression stroke, the intake and exhaust valve clearances for that cylinder can be adjusted; 2. After completing the adjustment, rotate the crankshaft and use this method to progressively adjust the valve clearances for the remaining cylinders. An engine is a machine capable of converting other forms of energy into mechanical energy, originally developed in England. It serves both as a power generation device and can refer to the entire machine including the power unit. Engine types include internal combustion engines, external combustion engines, electric motors, etc. The engine block forms the structural framework of the engine, serving as the mounting foundation for all engine mechanisms and systems. It houses all major engine components and accessories internally and externally, while withstanding various loads. Therefore, the engine block must possess sufficient strength and rigidity.
