Pistons are the reciprocating heart of the engine, converting combustion energy into mechanical force. Piston rings create a vital seal against the cylinder wall to maintain compression and regulate oil consumption. Worn pistons or damaged rings lead to significant power loss, increased emissions, and excessive oil consumption, often indicated by blue exhaust smoke and reduced engine efficiency.
