MHC and Other Conversions In A Natural Gas-Fueled Engine

Natural gas is one of the alternative fuels that has received considerable attention in recent years. It is believed that spark ignition engines designed to operate on natural gas may be able to meet emissions regulations of the ULEV. Natural gas has some interesting characteristics which engine designers may be able to use successfully to meet impending regulations. However, concerns have been raised on the type of suitable catalyst for such engines and whether existing catalysts designed for gasoline fuel would meet natural gas engine requirements. The work described in this paper was conducted to assess suitability of some of the existing catalysts in lowering natural gas engine emissions.
