Abstract	The burning of water ethanol blends has the potential to reduce NOx, CO, and HC emissions while reducing the ethanol fermentation production cost of distillation and dehydration by utilization of these blends. The torch style ignition produced by the catalytic igniter allows for the operation and cold start of an SI engine on ethanol/water fuels up to a 50/50 blend. This paper describes the operating characteristics of a catalytic igniter in a modified Co-operative Fuels Research (CFR) engine. Performance data was evaluated using a high speed in-cylinder combustion pressure analyzer. Emission data for premixed ethanol/water was also compared to separate water and ethanol injection for concentrations of 0–30% water in ethanol. Emissions and performance results for both fuel preparation methods were compared with engine operation on 100% ethanol. Premixed ethanol/water displayed significantly lower NOx and CO emissions and somewhat higher hydrocarbon emissions than separate water and ethanol injection. At a compression ratio of 10:1, the catalytic igniter configuration studied in this work was able to control cycle to cycle pressure variation even at high water fractions.
