FUEL ECONOMY AND EXHAUST EMISSIONS OF A METHANOL-FUELED CHEVETTE
This report presents the results of a series of tests conducted over a period of several months on a 1979 Chevrolet Chevette powered by anhydrous methanol. Baseline tests with gasoline were also conducted about three months before the methanol test series began. The exhaust emissions from this car were greatly affected by air-fuel ratio and state of tune. Driveability was not good during most tests when CO met Federal standards. The best optimized adjustments gave a 10 percent better energy efficiency on pure methanol than on gasoline with approximately similar exhaust emission levels.
