Study on the performance and Emission characteristics using castor and mustard seed oil mixture and diesel blend in C.I Engine

Abstract

Bio-diesel is one of the most promising alternatives for diesel needs..The present work has focused on the performance of castor non-edible vegetable oil and Mustard oil edible vegetable oil and its blend with diesel on a double cylinder, 4 stroke, naturally aspirated, direct injection, water cooled, eddy current dynamometer Kirloskar Diesel Engine at 1500 rpm for variable loads. Initially, castor eat oil and their blends were chosen. The physical and chemical properties of Castor oil, Mustard oil and its blend were determined. In general, viscosity of neat vegetable oil is high, which can be reduced through blending with diesel and heating them. The performance and emission characteristics of engine are determined using Castor and Mustard oil and their blends with diesel. These results are compared to those of pure diesel. Byanalyzing the graphs, it was observed that the performance characteristics are reduced and emission characteristics are increased at the rated load compared to those of diesel. This is mainly due to lower calorific value, high viscosity and delayed combustion process. From the critical analysis of graphs, it can be observed that 10% of Castor oil and Mustard oil mixture mixed with 90% of diesel is the best suited blend for Diesel engine without eating and without any engine modifications. It is concluded that castor and Mustard oil can be used as an alternate to diesel.
