Feiasibility Study of Direct Admitting of Pongamia Oil in I.C Engines

摘要

The increase in global warming, pollution due to the combustion of fossil fuels and its uneven distribution leads for the search of alternative energy source. Only few of them have done research with direct admitting of vegetable oil in C.I engine and this is due to reason of very high viscosity, lower heating value, low volatility and higher freezing point of vegetable oil. While in direct admitting of vegetable oil in C.I engines most of the authors says that the performance and emission characteristics depend on the viscosity, flash point, fire point, calorific value, density, cetane number. This paper reviews the characteristics of various non-edible vegetable oils, its performance and emission characteristics in C.I engines during direct admitting of vegetable oil. The yield of oil from a plant is an important factor in reliability of the fuel so some of the non-edible oil yielding plants, its yield and soil preference are also reviewed. From the review it can be concluded that non-edible oil could be a good alternative fuel which have a good reliability of oil production but direct admitting of vegetable oil for long term may reduce the engine life.
