An automotive engine mounted on a dynamometer is used to generate power, efficiency, and emissions maps which compare methanol with gasoline. This data is also used in conjunction with a computer program to predict vehicle performance and emissions. Methanol is found to offer advantages over gasoline. Two alternates to the stock fuel preparation system are also evaluated. They show improvements over the stock system. Computer modeling of the thermokinetic events in the test engine using methanol has allowed predictions of power, efficiency and emissions as functions of compression ratio, spark advance, air-fuel ratio and speed. High compression ratios appear beneficial. The report also considers engine wear, cold start aspects of methanol. It also presents some gas turbine evidence which favors methanol over commercial turbine fuel. (DePo)
