| Abstract: | On a type of JL368Q3 EFI gasoline engine fueled with methanol-gasoline fuel blends engine,performances,fuel economy and exhaust emissions were investigated.The volume percentage of methanol in gasoline is 85% respectively,named M85.The experimental results show that the engine power and torque increase when fueled with M85 compared with gasoline operation,while its thermal efficiency is improved remarkably.HC,CO and NOx emissions from the engine fueled with the above fuels were measured.CO and NOx emissions decrease obviously under all operating conditions.However,HC emissions increase dramatically. |
