| What is a piston ring | Piston ring is a metal ring embedded in the piston groove. There are two types of piston rings |
| function | The functions of piston ring include sealing, regulating oil (oil control), conducting heat (heat transfer) and guiding (supporting). Sealing: It refers to sealing the fuel gas to prevent the gas in the combustion chamber from leaking to the crankcase, so as to minimize the gas leakage and improve the thermal efficiency. Air leakage will not only reduce the power of the engine, but also deteriorate the oil, which is the main task of the air ring; Adjusting the engine oil (oil control): scrape off the excess lubricating oil on the cylinder wall, and at the same time make the cylinder wall covered with a thin oil film to ensure the normal lubrication of the cylinder, piston and ring, which is the main task of the oil ring. In modern high-speed engines, special attention is paid to the role of piston rings in controlling oil film; Heat conduction: heat of the piston is transmitted to the cylinder liner through the piston ring for cooling. |
