Previous research has developed a set of high efficiency generator engines converted from a stock automobile engine. These all employed different variations of squish and swirl along with running at a high compression ratio in their design. The stock engine was a 1.6L four cylinder engine fueled by propane and configured for lean operation. These modifications produced a 36.8% reduction in EPA cycle fuel consumption. The objective of this research was to determine whether this high efficiency engine could meet stringent regulated emissions standards set by the EPA. By varying spark advance and air-fuel ratio, an engine was created to meet EPA standards which had an increase of 1.7% in fuel consumption over the high efficiency engine without having to use a catalyst. Therefore, this engine could be produced cheaply and sold in the United States or abroad.
