Experimental Investigation on the Effect of Bioethanol on Emission Performance of Diesel Engine for Rapeseed Biodiesel-Diesel Blends

Abstract:

Global warming and climate change are the motives to find a solution for emission reduction of diesel engines. Bioethanol is renewable fuel which can be used in diesel engine as a part of biodiesel-diesel blends. The effect of bioethanol on the emission performance of diesel engine for rapeseed biodiesel-diesel blends as a function of engine load is evaluated in this paper. KDE 6500E diesel generator is used for this purpose. Carbon monoxide (CO), unburned hydrocarbons (HC), oxygen (O₂) and carbon dioxide (CO₂) emissions are recorded with the help of VLT-458 exhaust gas analyzer. Blends with higher concentrations of bioethanol have shown lower CO emissions while HC emissions increase with the increase in bioethanol concentration in the blends. CO₂ emissions are recorded more at higher loads for all types of biodiesel and bioethanol concentrations than that of diesel fuel.
