Theoretical modeling and experimental studies on vegetable oil fueled conventional engine

Abstract

Experimental analysis of the engine with various vegetable oil and its blends requires enormous effort, money and time. Hence a theoretical method based on various existing process models has been developed for the performance evaluation of a compression ignition engine by using diesel and Jatropha straight vegetable oil as an input fuel. The performance tests are carried out on a compression ignition engine using diesel, jatropha oil (unheated) and jatropha oil (preheated) as fuel. The effects of fuel injection pressure and fuel inlet temperature on the engine performance and emission for different fuels are also analyzed using this model. The comparisons of theoretical and experimental results are discussed. Engine performance characteristics predicted by this model are in closer approximation to that of experimental results.
