What is the reason why the hand pulled gasoline engine is not compressed?

The following are the following cases:

1. The fuel channel is blocked. Check whether the small hole for air intake on the lower fuel tank cap is blocked; From the tank to the carburetor.

At the inlet pipe, whether the oil circuit is unblocked. Treatment: Clean with compressed air and car servant.

2. The carburetor has heat infiltration. The engine overheated, causing the carburetor to overheat, causing the gasoline to boil, causing an improper mix of gases. Solution: Disassemble the outer cover of the engine and clean up the debris and dust inside.

3. The silencer is blocked. Cause poor breathing.

4. There is a problem with the igniter. When the engine is warmed up, it causes no ignition, or abnormal ignition.

5. Carbon deposition of piston and cylinder.

Severe, poorly compressed, completely disassembled.

The main reason why the hand-pulled gasoline engine is not compressed is that the valve is leaking or there is a problem with the piston ring, because there is no compression, mainly these two reasons. It is estimated that the piston rings and valves will be repaired.

Reason: The engine is not compressed, which may be caused by the valve closing is not tight, and there is also a lack of air intake! The second is that the piston ring and cylinder liner are not well sealed.

Cracks in the cylinder block or cylinder head, as well as damage to the cylinder gasket, can also result in no cylinder pressure. In severe cases, it will cause inability to start, and the slight engine will shake and accelerate weakly. Performance:

Engines with low compression ratios, gasoline molecular vapors.

1. If the carburetor is not smooth, clean it with compressed air and car servants. 2. If the gasoline is impure or there is water or other impurities in the fuel tank, the machine can start at idle speed, but the speed of the refueling engine is unstable, and the throttle will be turned off. Clean the fuel tank and replace the **93 gasoline.

3. The engine oil of the organic oil alarm can not be missing, otherwise it is easy to occur when the lowest critical point is around. 4. The piston and cylinder have serious carbon deposits, poor compression, and are completely dismantled.

The main reason is that it is difficult to start or cannot start, and the reasons include the failure of the circuit system, the failure of the fuel supply system and the failure of the cylinder compression ratio is insufficient.

The failure of the best small gasoline engine (small chain saw, lawn mower, hedge trimmer, etc.) is mainly difficult to start or cannot start, due to the failure of the circuit system, the failure of the fuel supply system and the failure of the cylinder compression ratio is insufficient. In general, these three failures do not occur at the same time. Therefore, when the gasoline engine is difficult to start or cannot start, do not be in a hurry, and should judge the cause and location of the fault according to the following methods and steps

What is the reason why the diesel engine suddenly has no compression, one is the problem inside the cylinder, that is, the piston ring or cylinder is particularly worn, and it also completely loses its tightness, so it causes the diesel engine cylinder to have no compression pressure. Second, the problem may lie in the valve mechanism, that is, the intake and exhaust door will fall off the block or ablation, so that the cylinder loses its tightness, resulting in no compression pressure for the diesel engine cylinder. Third, the cylinder gasket is ablated or washed out, which makes some of the cylinders of Shibi lose their tightness, resulting in no compression pressure of the diesel engine cylinder.
