Emission Analysis Of Butanol and Waste Cooking Oil in VCR Diesel Engine

Abstract

Environmental pollution and depleting energy resources are two major reasons to find a suitable alternative fuel. The experimental study is carried out on a variable compression ratio engine to compare the emissions produced by the engine using the blends of waste cooking oil and that of butanol, separately with the emissions produced by the same engine using neat diesel on the different compression ratio and loads.  The blends were prepared on the basis of percentage by volume, B10/WCD10 (10% Butanol/WCO and 90% Diesel), B20/WCD20 (20% Butanol/WCO and 80% Diesel) and B30/WCD30 (30% Butanol/WCO and 70% Diesel). Emission analysis of these bio-fuels showed that blends of waste cooking oil produced least NOx as compared to the butanol blends and neat diesel, therefore, bio-fuel of waste cooking oil can be used in a diesel engine with a compression ratio of 18. From the study, it can be deduced that waste cooking oil blends can be used as alternative fuel for compression ignition engines with the compression ratio of 18.
