INFLUENCE OF INJECTION PRESSURE ON PERFORMANCE PARAMETERS OF SEMI ADIABATIC DIESEL ENGINE WITH CRUDE VEGETABLE OIL WITH MAGNETIC INDUCTION

Abstract

Increase of injector opening pressure has a significance effect on performance and formation of pollutants inside the direct injection diesel engine combustion. Compression ignition (CI) engines are used to move major portion of the world’s goods, power much of the world’s equipment, and generate electricity more economically than any other device in their size range. Increasing industrialization of developing countries is resulting in increased demand for diesel worldwide. Substitution of this demand with straight vegetable oils (SVOs) is comparatively environmentally benign compared to diesel and biodiesel. However, drawbacks associated with crude vegetable oil of high viscosity and low volatility, which cause combustion problems, call for low heat rejection (LHR) engine or semi adiabatic diesel engine with its significant characteristics of maximum heat release and ability to handle the low calorific value fuel. LHR engine consisted of ceramic coated cylinder head. A hydrocarbon fuel was polarized by exposure to external force such as magnetism. The result of which is of course, more complete and rapid burning of the hydrocarbon fuel. Investigations were carried out to determine performance parameters of brake thermal efficiency, brake specific energy consumption, exhaust gas temperature, coolant load and volumetric efficiency with conventional engine (CE) and LHR engine with and without magnetic induction with vegetable oil operation with varied injector opening pressure. With vegetable oil with LHR engine with magnetic induction improved performance, when compared with CE
