EXPERIMENTAL INVESTIGATION ON CI ENGINE USING NON-EDIBLE BIODIESEL WITH OXY-GAS GENERATOR

Automobile Engineering

Since biodiesel is a renewable type of fuel, as well as produces low levels of emissions compared to conventional diesel, its usage has significantly increased recently. Apart from using biodiesel as a cleaner alternative for conventional diesel, other ways of enhancing the performance of the diesel engine, and minimizing emissions include employing H2 rich gas as fuel enhancer and using EGR systems for diesel engines. This investigation involved the use of a four-stroke direct injection (DI) diesel engine with various percentages of silk cotton seed biodiesel mixed with diesel and HHO at a rate of 2 LPM and 4 LPM introduced into the intake manifold through electrolysis. This was done to enhance the performance of the engine through the assumed synergism between the two fuels. In addition, the same engine, under similar load parameters (that is 0, 25, 50, 75 and 100% loads) was employed to determine the effects of EGR on the emission resulting from the same combination of fuel. The findings revealed that biodiesel in conjunction with hydrogen enhanced combustion improves the performance of the engine, thus being viable alternatives in CI diesel engines.
