How to adjust the valve of Suzuki Swift

Excessive engine valve clearance will reduce the valve lift, resulting in insufficient inflation and poor exhaust, and will also bring abnormal noise. If the gap is too small, the valve will not close tightly when working, resulting in leakage, which is easy to make the valve and valve seat

Excessive engine valve clearance will reduce the valve lift, resulting in insufficient inflation and poor exhaust, and will also bring abnormal noise. If the clearance is too small, the valve will not close tightly when working, resulting in leakage, which is easy to ablate the valve and valve seat working face. Therefore, the valve clearance should be carefully adjusted according to the specified standards to ensure the normal operation of the engine.

When the valve is completely closed and the valve driving mechanism is located in the base circle of the cam, check and adjust the valve clearance. Therefore, when the cylinder compresses the top dead center, the valve clearance of the intake valve and the exhaust valve is usually adjusted at the same time, that is, the valve clearance of the intake valve and the exhaust valve of the cylinder pointed by the ignition head. This method is called cylinder-by-cylinder adjustment.

In practical work, the following adjustment methods are often adopted: "within the line, within the line first" or "double exclusion". Using this method, the valve clearance of the whole valve can be adjusted only by shaking the crankshaft twice.

1) three-cylinder engine (Tianjin Li Xia TJ376Q engine)

When the cylinder 1 is located at the compression top dead center: when the camshaft semicircle key is located directly above.

Adjustable: 1 cylinder, 2 cylinders and 3 cylinders

go in and out

After turning the crankshaft once:

Adjustable: entrance and exit

2) four-cylinder machine

a、 1 - 3 - 4 - 2 4 - 2 - 1 - 3

Double row does not enter, double row does not enter.

b、 1 - 2 - 4 - 3 4 - 3 - 1 - 2

Double row does not enter, double row does not enter.

3) Five-cylinder engine (starting from 8 1, Volkswagen of West Germany introduced in-line five-cylinder engine)

1 - 2 - 4 - 5 - 3

Double row can't get in.

4 - 5 - 3 - 1 - 2

Double row can't get in.
