Description: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 1, 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.
