Study of Performance and Emission Characteristics of Non-Edible Biodiesel as a Sustainable Fuel in Diesel Engine

Abstract

Now a day's energy is the key concern for the whole world. Fossil fuels are limited in the world therefore scientist and researchers are looking for new renewable and sustainable source of energy. Vegetable oil plays an important role for the substitute of petro diesel. More than 300 oil-bearing crops edible and non-edible are known. Using of edible oil as a source of energy unnecessary creates an issue of food vs. fuel. Therefore, now researchers are working on non-edible source of energy. This paper discusses the role of non-edible biodiesel as an alternate fuel. It compares the performance and emission behaviour of non-edible oil specially found in South Asia region. Jathropha, Karanja, Neem, rubber seed, castor and Mahua are some important source of bio fuels. It is reported that performance and emission characteristics of non-edible biodiesel are comparable with diesel. Moreover non-edible biodiesel blend with limited amount (up to 20 %) can be replaced with petro diesel without any engine modification.
