摘要

Biodiesel from pure and used canola oil is produced by transesterification process in this study. Quality of biodiesel is examined according to ASTM 6751: biodiesel standards and testing methods. Important fuel properties of biodiesel, such as heating value, cetane index, viscosity, and others are also investigated. A direct injection (DI) diesel engine is tested with biodiesel-diesel and canola oil-diesel blends for performance and emissions at high idling operations. Three fuel series are examined: pure canola biodiesel, used canola biodiesel and pure canola oil series. In all the series, fuels are blended with petroleum diesel 2-20 vol.%. Engine performance is examined by measuring brake specific fuel consumption and fuel conversion efficiency. The emission of carbon monoxide (CO), hydrocarbon (HC), nitric oxide (NO), nitrogen dioxide (NO_2), nitrogen oxides (NOx), carbon dioxide (CO_2) and others are measured. Pure and used canola biodiesel blends show very similar fuel properties, engine performance and emissions. CO and HC emissions from biodiesel-diesel blends are significantly less than neat diesel fuel. Even pure canola oil up to 5% in diesel fuel can show significantly less CO emissions than that of diesel fuel. Up to 5% biodiesel and canola oil in diesel fuel, NOx emissions either can reduce or maintain similar level to that of diesel fuel.
