Purpose : Gasoline type engine, such as a diesel-type piston and cylinder of the engine in various kinds of engine piston of an improved method for applying chemical treatment on the surface. Constitution : To reduce the surface frictional force of the piston, the method of chemical treatment, the piston is placed in a container, a piston immersed in oil until the machine is completely filled, 220-250 °C rises in temperature, the oil (machine oil and additive 100% and a weight of all) 0.3-1.0% by weight of alkali metal carbonate, 0.3-1.0% by weight of the alkali metal nitrite, 0.20-0.60% and alkali metal chloride 1.0-1.6% cerium containing rare earth metal powder weight is heavy, the temperature at a time is held 10-24, thereafter, oil bath by natural cooling, is cooled below the piston 50 °C obtained is taken. Effect : Good working efficiency of a cylinder, its long useful life, and reduce the consumption quantity of engine oil, such as an air compressor or an automobile exhaust is less useful in industrial waste gas.
