How to set the valve of eight-cylinder engine

For the adjustment of valve clearance of cylinder 8, please refer to the action steps of cylinder 6 1-5-3-6-2-4. After adjusting the valve clearance, it needs to be re-studied until it meets the equipment requirements. In practical work, as long as we know the arrangement and working sequence of valves, we can easily adjust the valve clearance, save time and improve efficiency. The valve clearance adjustment method of 8-cylinder engine adopts the method of 1-5-4-2-6-3-7-8 ignition sequence to adjust the valve clearance. The specific adjustment sequence is as follows: 1, 1 cylinder to top dead center, 1 cylinder intake and exhaust valves, exhaust valves of cylinders 5, 4 and 2, cylinder 6 stationary, and intake valves of cylinders 3, 7 and 8 adjusted; 2. After driving the crankshaft for 360 revolutions, make the piston of cylinder 6 reach the top dead center, adjust the intake and exhaust valves of cylinder 6, exhaust valves of cylinder 3, cylinder 7 and cylinder 8, and keep 1 cylinder still, and intake valves of cylinder 5, cylinder 4 and cylinder 2; 3. The function of the valve is to inflate the engine and exhaust the exhaust gas after combustion. The engine is structurally divided into an intake valve and an exhaust valve.
