Piston with oxidation catalyst |
摘要 |
Pistons reciprocating in cylinders of a hydrocarbon-fueled internal combustion engine tend to trap air and unburned fuel between the top of the piston head and its enclosing cylinder wall. The circumferential side surface (or land) of the piston head above its upper piston ring groove is provided with a thin coating of porous aluminum oxide. Particles of an oxidation catalyst for the engine's fuel are electrolytically deposited in the pores of the oxide coating. During engine operation the oxide-supported catalyst particles promote combustion of the entrained fuel.
