How to adjust the valve of eight-cylinder engine

Cars have become an essential tool for everyone to travel. Of course, automobile knowledge is essential. In order to facilitate everyone to understand this knowledge, today Bian Xiao will introduce how to adjust the valve of an eight-cylinder engine. Interested friends can learn about it, which may be helpful to you.

Adjustment method of valve clearance of 8-cylinder engine: Adjust the valve clearance according to the ignition sequence of 1-5-4-2-6-3-7-8. The specific adjustment sequence is as follows: 1. Set 1 cylinder to top dead center, and adjust the intake and exhaust valves of 1 cylinder, exhaust valves of cylinders 5, 4 and 2, and intake valves of cylinders 3, 7 and 8 without moving cylinder 6. 2. Then rotate the crankshaft 360 degrees to make the piston of cylinder 6 reach the top dead center. When 1 cylinder is stationary, adjust the intake and exhaust valves of cylinder 6, exhaust valves of cylinder 3, cylinder 7 and cylinder 8, and intake valves of cylinder 5, cylinder 4 and cylinder 2. The valve is specially responsible for inputting air into the engine and discharging exhaust gas after combustion. The engine structure includes an intake valve and an exhaust valve. The function of the intake valve is to draw air into the engine and mix it with fuel for combustion; The function of the exhaust valve is to exhaust the exhaust gas after combustion and dissipate heat. The detection and adjustment of valve clearance is an important part of engine maintenance. In most cases, the valve maintenance of the engine basically needs to be checked and adjusted regularly (for example, German FL 5 13 series air-cooled diesel engines technically require that the valve clearance be checked and adjusted every 1000 hours).
