Piston rings / STD + 0.50 / Ø 78.50 mm / Mitsubishi S3L / S4L

Piston rings (piston %C5% 82ok-engine-std050- %C3% B87850-mm-mitsubishi-s3ls4l-31a17-07100.html">31A17-07100 ) with a diameter of 78.50 mm for Mitsubishi tractors and other machines with Mitsubishi S3L, Mitsubishi S4L and other engines.

Piston rings seal the space between the piston walls and the cylinder walls. During the combustion of the fuel mixture in the engine chamber, chemical energy is exchanged for mechanical energy, which is why we care about the tightness of these two elements. The second important role played by piston rings in the engine is to scrape excess oil from the cylinder walls during the piston's movement, thus ensuring proper lubrication. In combustion engines, we distinguish three basic types of rings:

• sealing rings,
• scraper rings,
• compression-scraper rings.

When replacing the rings, special attention should be paid to the order in which they are placed on the piston. The rings are installed in the correct order, the scraper ring is installed first, the sealing ring second and the oil ring is installed third.
