• Abstract

In the scenario of fast depletion of fossil fuels and increase of pollution levels the search for alternative fuels has become pertinent. Particulate emissions and oxides of nitrogen are exhaust emissions from diesel engine cause health hazards once they are inhaled in. They also cause environmental impact. Hence control of these pollutants is an immediate task and urgent. Crude vegetable oils are important substitutes for diesel fuel, as they are renewable, and have comparable properties with diesel fuel. However, drawbacks associated with crude vegetable oil of high viscosity and low volatility which cause combustion problems, call for low heat rejection (LHR) 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. Exhaust emissions of particulate emissions and oxides of nitrogen (NOx) were determined at full load operation with conventional engine (CE) and LHR engine with and without magnetic induction with vegetable oil operation. LHR engine with crude vegetable oil operation with magnetic induction improved exhaust emissions when compared with CE with vegetable oil operation.
