The small gasoline engine block refers to the gasoline engine of a small gasoline engine, such as a motorcycle. How can the small gasoline engine block be maintained?
Small gasoline engine cylinder body maintenance and maintenance should be combined with the engine noise to judge, mainly including the engine speed, different location, cold and hot conditions to think about three factors.
Piston knocking sound: after a period of use of the engine, the piston and cylinder body will have different degrees of wear and tear, and then increase the gap between them. During the operation, the gap between the piston and the cylinder body causes the piston to swing in the cylinder body.
Abnormal sound location: the knock between the piston and the cylinder wall shows a crisp "Dangdang" sound.
The effect of cold and hot conditions: because the engine is in the hot car condition, the piston and cylinder body will be reduced by the heat expansion, and the noise will be reduced relatively.
Note: if the noise is completely absent in the hot car, the engine operation is normal. If a larger percussion noise is present in the hot car, the piston or cylinder body should be replaced.
Knocking of piston pin: the gap between piston pin and connecting rod small head will increase gradually during engine running. If the gap is too long, it will form a clicking noise.
Abnormal sound location: the sound will occur on the left side of the engine.
The influence of heat and cold condition is that the noise is more obvious in hot cars.
Note: after abnormal noise, it should be checked in time to replace piston pin and connecting rod small head.
The knocking sound of the valve: when the valve is not adjusted or the screw is loosened, the valve and the adjusting screw will be clatter when the air gap is too large.
