Abstract

In the reported experiments, a multicylinder, carburretted engine was fueled with blends of 0, 20 and 30 volume percent methanol in a base stock representative of unleaded gasoline (viz. Indolene). The engine was operated under steady state conditions at constant speed, manifold vacuum and MBT spark advance over a range of fuel-air equivalence ratios. Comparisons were then made of performance and emissions characteristics for the various blends at equal equivalence ratios. It is concluded that at the same engine speed (2000 RPM) the MBT spark advance was the same for all of the blend levels tested (0, 20, 30%M). The 20 and 30%M blends produced the same torque with the value being approximately 2% greater than the Indolene-fueled torque value. Volumetric efficiency was not affected by the blend level. Carbon monoxide emissions were not affected by the blend level. Nitric oxide (NO//x) mass emissions were found to decrease with increasing blend level.
