  • Abstract

Vegetable oils, which are renewable fuels, can be effectively used to combat fuels shortage in developing countries and at the same time bring back degrade lands into cultivation. Experiments were carried out to evaluate the performance of diesel engine with ceramic coated cylinder head with crude vegetable oil with varied injector opening pressure. Performance parameters [brake thermal efficiency, exhaust gas temperature, coolant load, volumetric efficiency and sound levels] were determined at various values of brake mean effective pressure (BMEP) of the the ceramic coated combustion chamber and compared with neat diesel operation on conventional engine (CE) and vegetable oil operation at similar operating conditions. Engine with LHR–1 combustion chamber with vegetable oil operation showed improved performance at manufacturer’s recommended injection timing of 27obTDC, and the performance improved marginally with increased injector opening pressure and comparison with CE with diesel and vegetable oil at 27obTDC.
