Gasoline engine piston ring

Gasoline engine piston ring

Product Description

Piston rings are metallic split rings that are attached to the outer diameter of a piston in an internal combustion engine or steam engine. They form a seal between the piston and cylinder wall, which prevents pressurized combustion gases from entering the oil sump and regulate oil consumption by preventing excessive oil from entering the combustion chamber and burning.

The function of piston rings includes sealing, regulating oil (oil control), heat conduction (heat transfer), guidance (support) four roles. Sealing: refers to sealing gas, do not let the combustion chamber gas leakage to the crankcase, the gas leakage is controlled at a minimum, improve thermal efficiency. Gas leakage will not only make the power of the engine drop, but also make the oil deteriorate, which is the main task of the gas ring; Regulating oil (oil control): Scrape off the excess lubricating oil on the cylinder wall, and at the same time make a thin oil film on the cylinder wall to ensure the normal lubrication of the cylinder, piston and ring. In modern high-speed engines, special attention is paid to the role of the piston ring in controlling the oil film; Heat conduction: The heat of the piston is transferred to the cylinder liner through the piston ring, which plays a cooling role. According to reliable data, 70-80% of the heat received by the piston top is dissipated through the piston ring to the cylinder wall. More detasils please visit www.dypistonring.com
