Piston rings seal the space between the piston and cylinder walls. During combustion of the fuel mixture in the engine chamber, chemical energy is exchanged for mechanical energy, which is why the tightness of these two components is crucial. Another important role of piston rings in an engine is to scrape excess oil from the cylinder walls during piston movement, ensuring proper lubrication. There are three basic types of rings in internal combustion engines:
- sealing rings,
- scraper rings,
- compression-scraper rings.
When replacing the rings, pay particular attention to the order in which they are positioned on the piston. Install the rings in the correct order: the oil control ring first, the compression ring second, and the oil seal ring third.

First signs of wear of piston rings:
- higher fuel consumption,
- loss of engine oil,
- power loss,
- black smoke from the exhaust pipe of a hot engine,
- uneven engine operation at idle speed,
- unnatural, easily audible sound from the engine area,
- power loss,
- problems with starting the engine,
All symptoms should be consulted with a professional service for proper diagnosis and checking the engine for the need to replace the rings or repair the engine.
