Abstract
PRECISION COMBUSTION, INC., PROPOSES TO EXPLORE CATALYTIC COATINGS ON THE COMBUSTION CHAMBER WALLS OF SMALL UTILITY ENGINES IN A CONTINUING MODIFICATION OF SMALL GASOLINE ENGINES SO THAT ULTIMATELY THEY WILL BE ABLE TO OPERATE AT TRULY LEAN FUEL/AIR RATIOS FAVORING LOW HC, CO, AND NOX EMISSIONS. THE CURRENT SIMPLICITY OF THESE ENGINES OFFERS SOME GOOD OPPORTUNITIES FOR THIS APPROACH TO SUCCEED. A SPINOFF BENEFIT WOULD LIKELY BE TECHNOLOGY TO SIMILARLY MODIFY THE MORE-COMPLEX AUTOMOTIVE OTTO-CYCLE ENGINE BY COMPILING RESEARCH DATA ON THE EFFECT OF CATALYTIC SURFACES ON ENGINE PERFORMANCE AND EMISSIONS. IN PHASE I, SMALL ENGINE TESTING IN A WELL-INSTRUMENTED ENGINE TEST CELL WILL EXPLORE THIS CATALYTIC LEAN BURN CONCEPT ON A FOUR-STROKE ENGINE. IN PHASE II, THE CONCEPT WOULD BE CARRIED FORWARD TO ENGINE OPTIMIZATION.
