The piston ring is embedded in the piston groove and is a key component of the fuel engine. It is divided into two types: the gas ring and the oil ring: the gas ring is used to seal the compressed air in the combustion chamber, and the oil ring is used to scrape off the excess oil on the cylinder. For the installation of engine piston rings, pay attention to the installation sequence and orientation of the piston rings. Correct installation can ensure the normal operation of the engine. The following is the installation method of the engine piston ring.
The installation of engine piston rings requires the use of special fixtures. Pay attention to the installation sequence of piston rings during installation. Some engine piston rings use three rings, including two gas rings and one oil ring, while some use four rings, including three rings. Dao Qi ring and an oil ring. But the installation sequence is nothing more than installing from the bottom oil ring, and then in the order of the third gas ring-the second gas ring-the first gas ring (silver white).
After the engine piston ring is installed, you also need to pay attention to the direction and opening of the piston ring. Generally, the side with letters or numbers is upward, and there is no specific direction regulation for those without marking. The oil ring has no distinction between the front and the back. The openings of the rings should be staggered at an angle of 120° to prevent the combustible mixture from leaking from the opening gap of the piston ring when the engine is started, which makes the engine difficult to start.
