Function 2: adjust oil (control oil) | The main task of the oil ring is to scrape off the excess lubricating oil on the cylinder wall and 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 piston rings in controlling oil film; |
Function 3: heat conduction | The heat of the piston is transmitted 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 crown in the non cooling piston is transmitted to the cylinder wall through the piston ring, and 30-40% of the heat in the cooling piston is transmitted to the cylinder wall through the piston ring; |
