Emission Analysis of Diesel Engine by Cooking Oil Waste as Part Substitute of Fuel

Abstract

Methyl ester as biodiesel is one clean energy sources for fueling diesel engines. The adverse effects of the conventional fossil fuels and rise in fuel price have made researchers to carry out their researches on various sources of biodiesels. The process of producing biodiesel from vegetable oil is not so economical due to cost of the raw materials though there are reductions in emission gases from automobile exhaust. The cooking oil as waste is not eco-friendly and difficult to dispose. The same can be used as a part substitute to diesel to run internal combustion engine to economize the fuel cost, reduce environmental pollution, ameliorate the difficulties of unburnt cooking oil disposal. Recent study envisages an attempt to convert the waste cooking oil to fatty acid methyl ester (FAME) as a supplement to diesel. An internal combustion engine was run with different proportion by substituting with FAME acquired from cooking oil waste. The analyses of the noxious gases released have been conducted to find the concentration of noxious gasses by using Exhaust Gas Analyzer. The percentage of toxic gasses exhausted on running the internal combustion engines with extracted biodiesel at 10%, 20% and 30% mix were analyzed. The results revealed that the percentage of emitted gases like Hydrocarbon (HC), and Monoxide of Carbon (CO) were reduced and it was found optimum at a blend of 20% of biodiesel when added with 80% conventional diesel but need further work on it.
