Abstract:
Petroleum based fuels play a vital role in rapid depletion of conventional energy sources along with increasing demand and also major contributors of air pollutants. Energy demand is increasing drastically because of the fast industrial development, rising population, expanding urbanization, and economic growth in the world. This paper introduces different species of non-edible vegetables whose oils are potential sources of biodiesel. Various aspects of non-edible feedstocks, such as biology, distribution, and chemistry, the biodiesel’s physicochemical properties, and its effect on engine performance and emission, are reviewed based on published articles. From the review, fuel properties are found to considerably vary depending on feedstocks. The performance parameters of the test engine Viz. Brake thermal efficiency, Volumetric efficiency are decreased, Brake specific fuel consumption and Exhaust gas temperature are increased for all neat oils compared to diesel. Emission parameters of engine such as Carbon monoxide, Carbon dioxide, Un-burnt hydrocarbons and Smoke are increased, but Nitrogen oxides are decreased for all neat oils and their blends compared to diesel. This variation is observed due to high viscosity coupled with lower heating value of the fuels. In this process, the performance parameters of engine such as Brake thermal efficiency and volumetric efficiency are slightly decreased, Brake specific fuel consumption and Exhaust gas temperature are increased compared to diesel for all bio-diesels. Emission parameters of engine such as Carbon monoxide, Carbon dioxide, Un-burnt hydrocarbons and Smoke are reduced, but Nitrogen oxides increased for all bio-diesels compared to diesel. This trend is observed due to complete combustion of the bio-diesels, as the viscosity is reduced. It is observed that 25% of neat oil mixed with 75% of diesel is the best suited blend, without heating and without any modification of the engine. Analysis of the performance results revealed that the biodiesel generally give higher brake thermal efficiency and lower brake-specific fuel consumption. Emission results showed that in most cases, NOx emission is increased, and HC, CO, and PM emissions are decreases. It is observed that the combustion characteristics of biodiesel are almost similar to that of diesel. It was reported that a diesel engine could be successfully run and could give excellent performance and the study revealed the most effective regulated emissions on the application of different oils biodiesel and their blends as fuel in a CI engine.
