PREPARATION METHOD FOR CATALYST ON SURFACE OF WORK PIECE IN COMBUSTION CHAMBER OF INTERNAL COMBUSTION ENGINE

摘要

Provided is a preparation method for a catalyst on the surface of a work piece in the combustion chamber of an internal combustion engine, the method comprising injecting composite catalyst ions onto the surface of a piston in the internal combustion engine, the inner surface of the cylinders and cylinder covers, and other surfaces of inner components of the engine such as an air inlet valve. The oxidative reaction threshold value of carbon particles is reduced, which facilitates the catalytic burning of carbon particles, thereby reducing the build-up of carbon inside the internal combustion engine, enabling full burning of fuels, improving the efficiency of burning, and decreasing thermal pollution to the environment.
