CHARACTERIZATION AND RESEARCH INVESTIGATION OF METHANOL AND METHYL FUELS IN AUTOMOBILE ENGINES. FIRST YEAR REPORT

Methanol is compared with gasoline in steady state dynamometer test evaluations of power, thermal efficiency, and emissions. The reported comparisons are from OEM equipment with gasoline and low cost modifications of the fuel preparation system to accommodate methanol. Maldistribution of fuel-air mixture among the cylinders is severe for gasoline and somewhat worse for methanol. Even so, methanol is found superior in thermal efficiency. NOx emissions and equivalence ratio range is comparable with gasoline in power, hydrocarbons and CO. Methanol produces somewhat more aldehydes, particularly from lean equivalence ratios, but the absolute levels for both fuels are low. Also presented is some engine friction-wear data based on analysis of engine oil for various metals. Preliminary computer modeling of engine thermochemical processes predicts both emissions and performance in good agreement with experimental data.
