The Automotive ceramic gas turbine(CGT) is intended for operation at a turbine inlet temperature of 1,350°C and a turbine speed of 100,000 rpm.
High temperature lubricating oil has to satisfy the heat-resistant and lubricity under a severe condition such as a bearing temperature of 300 °C, a reduction gear tooth pressure of 1 GPa and a peripheral speed of 120 m/s.
The practical performance and durability tests of the high temperature lubricating oil based on polyolester were performed using a high-temperature and high speed bearing simulator and a high speed gear tester under the actual engine conditions.
