Compared with other kinds of machinery, the friction surfaces of the internal combustion engines have many particularities, especially with the continuous development of internal combustion engines with high speed, high strength, high power and exhaust gas pollution prevention. This particularity has become more prominent. According to the working conditions of internal combustion engines, their working characteristics are summarized as follows:

(1) High temperature, large temperature difference
(2) Fast movement speed
(3) Load weight
(4) Vulnerable to environmental factors

Due to different types, models and service conditions of internal combustion engines, the performance requirements for internal combustion engine oils are also different.

(1) Good viscosity temperature characteristics, proper viscosity
(2) Strong oxidation resistance and good stability
(3) It has good detergency and dispersion
(4) Good lubrication and wear resistance
(5) Good corrosion resistance and ability to neutralize acidic substances
