What is the method for adjusting valves in a four-cylinder car?

[DelLydia]

Four-cylinder car valve adjustment method is: 1. Rotate cylinder 1 to the compression top dead center aligned with the 0 scale line or align with the timing gear chamber pointer; 2. Adjust the intake and exhaust valves of cylinder 1, the intake valve of cylinder 2, and the exhaust valve of cylinder 3; 3. Rotate 360 degrees, then adjust the exhaust valve of cylinder 2, the intake valve of cylinder 3, and the intake and exhaust valves of cylinder 4. The function of valves is specifically responsible for introducing air into the engine and expelling exhaust gases after combustion. Structurally, they are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's function is to expel combustion exhaust gases and dissipate heat.
