Evaluation of Performance Characteristics of Pre-Heated Milk Scum Oil Bio Diesel on a Diesel Engine at Different Fuel Injection pressure

Abstract

Biodiesels are the main renewable and carbon neutral sources for compression ignition engines. The main reasons of technical problems arising from the use of various biodiesel are the high Surface Tension and the high viscosity. In the CI engine, high surface tension and viscosity causes improper homogeneity in charge and fuel atomization. Thus preheating is the method to decrease viscosity of the biodiesel. The preheating of biodiesel at different temperature like 45°C, 50°C by using the exhaust gases decreses the viscosity and surface tension which improves better fuel injection and there by improves performance of the engine. Preheating of biodiesel can be made by using special arrangement of exhaust manifold. Experiment is conducted at different fuel injection pressure 180bar, 200 bar.
