How to adjust the four-cylinder engine valve

The four-cylinder engine can be adjusted by cylinder. According to the cylinder ignition order, after determining the position of the stop point of a cylinder piston on the compression, the gap between the cylinder inlet and exhaust valves can be adjusted.

Four-cylinder engine valve adjustment, turn 1 cylinder to the compression stop point (there is a ruler on the crankshaft pulley or a mark on the crankshaft flywheel) and aim at the 0 scale line or the pointer of the timing gear chamber. Adjust the intake and exhaust valve of 1 cylinder, the intake valve of 2 cylinder, and the exhaust valve of 3 cylinder.

The order is 1-3-4-2. Turn the 1st cylinder to the compression stop point and adjust the near exhaust valve of 1 cylinder. Turn the crankshaft 180 degrees according to the working direction of the engine. Turn the 3 cylinder to the compression stop point and adjust the near exhaust valve of the 3 cylinder. Turn it 180 degrees again. Turn the 4th cylinder to the compression stop point and adjust the 4th cylinder near discharge stop point accordingly. Adjust the 2 cylinders accordingly. .

Cylinder-by-cylinder adjustment method: According to the ignition order of the cylinder, after determining the stop position of a cylinder piston on the compression, the gap between the inlet and exhaust valves of the cylinder can be adjusted; after adjustment, the crankshaft is shaken, and the valve gaps of other cylinders can be gradually adjusted according to this method. There are roughly four types of LLLL6 (the number represents the number of cylinders).

How to adjust the sixteen valves of the four-cylinder car? The following is an example of a four-cylinder engine with an ignition order of 1-3-4-2.

Adjustment method of four-cylinder engine valve

1. Adjustment of four-cylinder engine valve: turn 1 cylinder To the compression stop point (there is a ruler on the crankshaft pulley or a mark on the crankshaft flywheel), aim at the 0 scale line or the pointer of the timing gear chamber. Adjust the intake and exhaust valve of 1 cylinder, the intake valve of 2 cylinder, and the exhaust valve of 3 cylinder.

2. Four-cylinder engine valve adjustment, turn 1 cylinder to the compression stop point (there is a scale on the crankshaft pulley or a mark on the crankshaft flywheel), and aim at the 0 scale line or the timing gear chamber pointer. Adjust the intake valve and exhaust valve of 1 cylinder, 2 cylinder and 3 cylinders. Then turn 360° to adjust the 2-cylinder exhaust valve, 3-cylinder intake valve and 4-cylinder intake and exhaust valve.

3. Cylinder-by-cylinder adjustment method: According to the ignition order of the cylinder, after determining the stop position of a cylinder piston on the compression, the gap between the inlet and exhaust valves of the cylinder can be adjusted; after adjustment, the crankshaft is shaken, and the valve gaps of other cylinders can be gradually adjusted according to this method. There are roughly four types of LLLL6 (the number represents the number of cylinders).

Four-cylinder engineHow to adjust the valve (how to adjust the four-cylinder engine valve)

1. Adjust the intake and exhaust valve of the 1 cylinder, the intake valve of the 2-cylinder, and the exhaust valve of the 3-cylinder.

2. Common valve adjustment methods include: cylinder-by-cylinder adjustment method, secondary adjustment method, expression method, etc. However, due to the wide variety of engines, the order of the intake and exhaust valves is different. Using the above method to adjust the valve gap, there is a sense of inconvenient memory and complicated lock.

3. The first type is to compensate for the gap on the valve top rod with a standard gasket by measuring the valve gap value during assembly, but a new gasket must be padded after wear. The second is to adopt a hydraulic top rod. Its gap is automatically adjusted by the hydraulic top rod. If the hydraulic top rod is not broken, it does not need to be adjusted.
