Six-cylinder engine 12367 10 valve adjustment

The valve adjustment sequence formula of a six-cylinder engine is 12367 10, and its working sequence is 1, 5, 3, 6, 2 and 4. When the piston of 1 cylinder is at TDC, the intake and exhaust valves of 1 cylinder, the exhaust valves of cylinders 3 and 5, and the intake valves of cylinders 2 and 4 can all be adjusted.

After the crankshaft rotates 360 degrees, the piston of cylinder 6 is at the top dead center, and the intake valve and exhaust valve of cylinder 6, intake valve of cylinder 3 and 5, and exhaust valve of cylinder 2 and 4 can be adjusted.

If the working sequence is 1, 4, 2, 6, 3, 5, the valve adjustment sequence is recorded as line and advance; Send, input, run, input.

A six-cylinder engine can be adjusted by cylinder, that is, one cylinder at a time. According to the ignition sequence of the cylinder, when the compression stroke ends and the piston moves to the top dead center, the intake valve and exhaust valve of the cylinder are adjusted one by one. This adjustment method is more reliable.

First, loosen the lock nut, then insert a feeler gauge with the same thickness between the tail end of the valve stem and the rocker arm, pull the feeler gauge back and forth, and turn the adjusting nut to feel a slight resistance gap. Then, tighten the lock nut. Million car purchase subsidy
