　　gasoline engine oilLubrication characteristics and requirements for lubricating oil

　　High thermal load

　　Gasoline engines have high power and high speed (above 5000r/min), and are mostly air-cooled. Therefore, the thermal load is much higher than that of corresponding four stroke gasoline engines, and the surface temperature of the piston is very high. Lubricating oil is prone to form carbonaceous deposits at high temperatures. Causing ring sticking and cylinder pulling, therefore requiring lubricating oil to have excellent high-temperature cleanliness.

　　High mechanical load

　　Similar to the situation of thermal load, the mechanical load of gasoline engines is also significantly higher than that of corresponding four stroke gasoline engines. The cooling around the cylinder is uneven, with good cooling in the windward direction and poor cooling in the leeward direction during driving. Uneven thermal expansion and contraction cause cylinder deformation, making it easy to scratch and wear. Therefore, lubricating oil should have high oil film strength and extreme pressure performance.

　　gasoline engine oilProblems arising from the discharge of fuel after combustion

　　Lubricating oil burns together with gasoline and is discharged from the exhaust pipe, which is a major difference between gasoline engines. Due to the heavy fraction of lubricating oil, a large amount of deposits are generated after combustion, which can pose the following hazards to the normal operation of the engine: these deposits can clog the exhaust port, causing poor intake and exhaust flow, thereby reducing output power; Deposits are generated on the spark plug electrode, causing cross connections, resulting in a decrease in power or even shutdown, and also reducing the lifespan of the spark plug; The high-temperature deposits in the combustion chamber cause premature ignition, disrupt the working program, and result in a decrease in power.
