Combustion and emissions behaviour for ethanol–gasoline-blended fuels in a multipoint electronic fuel injection engine

摘要: The purpose of this study is to experimentally investigate the performance, combustion and pollutant emissions a multipoint electronic fuel injection gasoline engine using methanol–gasoline blends. results indicated that, with increase in methanol (CH3OH) content blends, maximum torque power are slightly decreased, brake specific consumption evidently increased thermal efficiency remains almost identical. At low loads speeds, observed have faster velocity, but blends at high speeds. carbon monoxide lower, hydrocarbon higher nitrogen oxide lower for M10 loads. formaldehyde CH3OH content, acetaldehyde show little variation.
