Piston ring is embedded in the groove of piston rod, which is the core component of gasoline and diesel engine. It can be divided into gas ring and oil ring: the gas ring is used to seal the air compression in the combustion chamber of the engine, and the oil ring is used to scrape off unnecessary automobile oil in the cylinder. For the installation of engine piston rings, special attention should be paid to the installation sequence and orientation of piston rings, and correct installation can ensure the normal operation of the engine. The following is the installation method of engine piston ring.

When installing the engine piston ring, you must use a special fixture and pay attention to the installation sequence of the piston ring. Some engine piston rings use three rings, including two gas rings and one oil ring, while others use four rings, including three gas rings and one oil ring. However, the installation sequence is only to install the bottom oil ring first, and then install it in the order of the third gas ring, the second gas ring and the first gas ring (silver).

After the engine piston ring is installed, you must also pay attention to the orientation and opening of the piston ring. Generally, the side with English letters or data is upward. Without signs, there is no actual house orientation requirement. Oil rings do not distinguish between positive and negative sides. The opening of each ring should be 120.
