The Effects of the Fuel Injection Pressure on the Performance and Emission Characteristics of VCR Engine Fuelled with Pupae Biodiesel-Diesel Blends

The usage of diesel Engine day by day extended considering their low fuel use and high efficiencies. A few endeavors were made for search of elective fuels due to extended natural contamination and exhaustion of conventional non-sustainable energy sources and prevailing in the improvement of Biodiesel as an elective fuel. An endeavor was made on Direct Injection Compression Ignition (DI-CI) engine using Pupae oil methyl ester blended in with diesel in various degrees to consider the engine performance and emission (outflow) at different injection pressures. The tests were led at consistent load at various injection pressures (200, 220, 240, 260 and 280 bar). In the current work performance qualities like Brake thermal efficiency (BTE), Brake Specific fuel consumption (BSFC), exhaust gas temperature (EGT) and outflow attributes like carbon monoxide (CO), oxides of nitrogen (NOX), unburnt hydrocarbon (UHC) and smoke opacity had been researched. From the outcomes it is seen that 260 bar injection pressure causes better execution and improved emission qualities, for all the fuel blends
