The Effect of Super Charging and straight vegetable oil (RBO) as an Additive in Diesel for Diesel Engines

The applications of diesel engines in the present scenario are vast. Generally these engines use conventional diesel oil as fuel. Probably in this century, it is believed that crude oil and petroleum products will become very scarce and costly to find and produce. The other major problem posed by these diesel fuels is air-pollution. This situation caused enticement in researchers to find a viable and alternative to conventional fuels and paved a way to alternative fuel technology. Many Straight vegetable oils have similar fuel properties to diesel fuel, except for higher viscosity and lower oxidative stability. If these differences can be overcome, Straight vegetable oil may substitute for diesel fuel. Straight Vegetable oils are renewable and their usage also helps to preserve diesel fuels for a longer time. In this project, the effect of supercharging is studied on the performance of a diesel engine with the use of Straight vegetable oil (RBO)as well as pure Diesel as fuels, under varying supercharging pressures. The performance of the engine is evaluated in both the cases in terms of various engine performance parameters (Brake power, Brake specific fuel consumption, exhaust gas temperatures, engine emissions etc.). The results are compared with these performance parameters in both Pure Diesel and Rice bran oil operation of the DI Single Cylinder Diesel engine.
