PROPANE AS AN ENGINE FUEL FOR CLEAN AIR REQUIREMENTS

AIR POLLUTANTS IN EXHAUST GAS PRODUCED FROM LP-GAS (PROPANE) STUDIED USING BOTH LABORATORY ENGINES AND VEHICLES. RESULTS SHOWED THAT ENGINES USING PROPANE AS COMPARED WITH GASOLINE CAN OPERATE OVER A WIDER RANGE OF A/F (AIR-FUEL RATIO) WITH MINIMUM CARBON MONOXIDE AND HYDROCARBON EMISSIONS. PROPANE AND NATURAL GAS EMISSION LEVELS WERE SIMILAR. NO SIGNIFICANT DIFFERENCE IN NITROGEN OXIDES WAS FOUND FOR THE THREE FUELS. IN SIMULATED TYPICAL CITY DRIVING USING PROPANE AS A FUEL, EMISSIONS WERE MARKEDLY REDUCED BY RETARDING IGNITION TIMING WITH A/F INCREASED TO APPROACH THE LEAN MISFIRE LIMIT. HOWEVER, SERIOUS POWER LOSS ACCOMPANIED ENGINE ADJUSTMENT FOR MINIMUM EMISSIONS. /JAPCA/
