Summary on Grant Application Form
This proposed research is motivated by the increasing concern with emissions of C02 and NOX emissions from IC engines. In the proposed research, two new technologies will be developed and applied to a gasoline engine in order to achieve a higher compression ratio and extended lean-burn or dilution limits. The first approach is to take advantage of variations in volatility and octane numbers between different components in a standard gasoline fuel by a novel fuel fractionating system. Fuel fractions derived from standard gasoline, each has superior properties over standard gasoline for meeting different attributes at full load and part load conditions. The high octane rating of the heavy fraction will be employed to improve engine performance and fuel economy at full load by increasing the maximum allowable compression ratio. Stratified fuel fractions will be used to extend the lean-burn or EGR dilution limits at part load by employing controlled autoignition combustion, which involves the ignition and burning simultaneously throughout the entire mixture at low combustion temperature and hence extremely low NOx emission. Exploitation with the stratified fuel fraction operation for each attribute would out-perform current engines in all aspects while using the same gasoline fuel. This will also provide a good answer to the possible European legislation on C02 emissions in the future as well as the stage IV and ULEV2 emissions compliance.
