　　Lubrication methods for gasoline engines

　　Gasoline engine oil and fuel premixed

　　After mixing lubricating oil with gasoline in a certain proportion, it enters the crankcase and cylinder through the carburetor. During the intake stroke, there is a certain degree of vacuum and some gasoline evaporates from the mixture on the hot surface of the components. The lubricating oil remains in the bearings and cylinder liners to lubricate the moving parts. A small amount of used oil is discharged, and most of it burns together with gasoline. The advantage of this method is that there is no lubrication mechanism, which simplifies the engine structure. The disadvantage is that the consumption of lubricating oil is high, and there is less oil intake during idle. The lubrication is not sufficient, and the combustion of lubricating oil will also deteriorate the exhaust quality.
