Oil Scraper Ring Piston

Two stroke cycle engines do.

Oil scraper ring piston. The oil ring is used to wipe excess oil from the cylinder wall during piston movement. Excess oil is returned through ring openings to the oil reservoir in the engine block. Hence oil scraper rings are additionally needed in the 4 stroke piston ring pack. The invention relates to an oil scraper piston ring 1 for internal combustion engines consisting of a flexible metal strip with a u shaped cross section with radially directed resilient legs 3.

Usually 2 4 compression rings are provided to seal the gases from the combustion chamber and 1 3 oil control rings are provided to excess avoid oil ingress in the combustion chamber. They must absorb the combustion pressure cool the piston keep the oil in the crankcase and provide a film of oil on the cylinder wall. Some rings of this type are installed with expander rings. Oil ring support rails are a different breed form your typical piston ring.

They are not designed to seal against the cylinder wall in fact they should never even come close to contacting the cylinder wall. This types of piston rings have slots between the upper and lower faces that carry on the cylinder wall. An oil ringis the piston ring located in the ring groove closest to the crankcase. Piston rings play a very important part in internal combustion engines.

Oil ring explanation pov installation. The oil scraped off the cylinder wall moves into the slots in the back of the oil ring grooves in a piston and from there it returns to the oil pan. How to install piston rings and not break them bonus. Our rings function in sets usually a top compression ring second groove compression or oil scraper ring and oil control ring and range from 1 125 to 8 875 bores.
