judge When the engine is running, some pistons knock abnormally. The abnormal sound of the piston knocking on the cylinder occurs at the upper part of the cylinder, which is a rhythmic "rattling" sound similar to that of hitting the concrete floor with a small hammer. When the engine is idling, the sound is obvious and clear. Especially when the engine is running at low temperature, the sound is obvious. When the temperature rises, the sound will reduce or even disappear |
| Piston structure |
The piston head is machined with several grooves for installing piston rings. The number of piston rings depends on the sealing requirements, and it is related to the engine speed and cylinder pressure. High speed engines have fewer rings than low speed engines, and gasoline engines have fewer rings than diesel engines. General gasoline engines use two gas rings and one oil ring; The diesel engine has three gas rings and one oil ring; Low speed diesel engine adopts 3~4 gas rings. In order to reduce friction loss, the height of the ring belt should be reduced as much as possible, and the number of rings should be reduced as much as possible under the condition of ensuring the sealing. |
