6-cylinder engine valve adjustment sequence formula, 6-cylinder valve adjustment formula 12367 10

The valve adjustment sequence formula of a six-cylinder engine is 12367 10, and its working sequence is 1-5-3-6-2-4. When the piston of 1 cylinder is at the top dead center, the intake valve and exhaust valve of 1 cylinder, exhaust valves of cylinders 3 and 5, and exhaust valve of cylinder 2 can all be adjusted. After the crankshaft rotates 360 degrees, the piston of cylinder 6 is at the top dead center, so 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. A six-cylinder engine can be adjusted cylinder by cylinder, that is, one cylinder at a time. Mainly according to the ignition sequence of cylinders, at the end of the compression stroke and when the piston moves to the top dead center, the intake valve and exhaust valve of cylinders are adjusted cylinder by cylinder. This adjustment method is more reliable. Loosen the lock nut first, 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, turn the adjusting nut, and then tighten the lock nut.
