压燃式发动机燃用F-T柴油/生物柴油混合燃料的燃烧及振动特性研究
Combustion and vibration characteristics of a compression ignition engine fuelled with F-T diesel-biodiesel blends
摘要
Abstract
In this study, in order to build high-quality clean alternative fuels to achieve complementarity Fischer-Tropsch (F-T)diesel and biodiesel performance,experimental tests were investigated, which evaluated the combustion and vibration characteristic of a turbocharger diesel engine,using F-T diesel and F-T diesel blending of 10%, 20%and 30%biodiesel.During tests,a four-cylinder turbocharged DI diesel engine at various load and 2 000 r/min engine speed performed in the steady state conditions. With the increase of biodiesel content, the ignition delay of mixed fuel increased slightly, and the burning start point as well as the combustion duration increased. The ratio of pressure rise increased with the increase in proportion of biodiesel in the fuel blends, but both lower than diesel's. In addition, the results showed that the mixture fuel's combustion duration was longer than diesel's.In comparison with diesel fuel, vibration of engine filled with the diesel-biodiesel blend fuel has the lower vibration (RMS). As biodiesel increased in proportion, the vibration characteristic of kurtosis value was increased.And B30FT has the highest value of the kurtosis which was 17.3%higher than diesel at 150 N·m.关键词
