Development of Catalytic Converter for 2 - Stroke Engine Powered Vehicles 2004-01-1090

Scooters and motorcycles are favoured as economical forms of transportation throughout much of Asia. This is particularly true of vehicles with 2 stroke power plants, thanks to the high specific output produced by the simple, less costly engine. However a serious disadvantage of these vehicles is that they emit considerably higher volumes of gaseous pollutants per driven kilometer than do other automobiles. This paper presents new development of a catalytic converter for 2 stroke powered vehicles which uses metallic catalyst support coated with platinum. With an improved inlet header design the conversion efficiency has improved significantly and maximum power loss was than 5 % over the entire speed range.
