Performance Analysis of a Spark Ignited Engine with ETBE as a Blending Agent

The performance of a SI engine with Ethyl Tertiary Butyl Ether (ETBE) as a blending component was investigated in comparison with other blending components; ethanol and Methyl Tertiary Butyl Ether (MTBE). With oxygenated fuel blends of 2.0 and 3.5 wt. % oxygen content, parametric studies were carried out on emission levels and the overall performance with a General Motors Quad-4 engine. The results of the experiments and the numerical simulation with the computer program, ZMOTTO, show that the new blending component, ETBE, can be compared favorably with the performance and emission levels of the base gasoline, ethanol, and MTBE.
