Influence Of Varied Injection Timing On Exhaust Emissions With Crude Jatroph Oil On Di Diesel Engine With High Grade Insulated Combustion
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering
Abstract
Depletion of fossil fuels and increase of pollution levels with fossil fuels, search for alternative fuels has become Inevitable. Increased the importance of vegetable oils as their properties are comparable to diesel fuel.Experiments were conducted to study performance of diesel engine with crude jatropha oil with 3mm air gap insulated piston, 3mm air gap insulated liner and ceramic coated cylinder head. Air gap of 3mm were maintained by screwing the crown to the piston body. Crown was made of superni-90 whose thermal conductivity is poor. Air gap of 3mm was maintained by inserting the suprni-90 insert into the liner.Exhaust emissions [particulate emissions and nitrogen oxide levels] were determined at various values of brake mean effective pressure (BMEP) of the high grade Low Heat Rejection Combustion chamber(LHR?3) with crude jatropha oil at varied injection timing and compared with neat diesel operation at a injector pressure of 190 bar.
