Combustion of biodiesel in CI engine
Biodiesel is one of the promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine with little or no modification in the engine. In the present article an overview of combustion characteristics of CI engine running with biodiesel is described. The tests on engine running with different fuels (biodiesel and diesel) have resulted in almost overlapping P-V diagrams. The power output values for both the diesel and biodiesel fuels are almost the same. The engine running with biodiesel has produced slightly higher incylinder pressure and peak heat release rate than the engine running with normal diesel at all operating conditions. Furthermore, the brake specific fuel consumption values for the engine running with biodiesel are higher than the engine running with normal diesel. These studies showed that biodiesel is good gas oil substitute but an increase in the nitrogenous oxides emissions was observed at all operating conditions. The rates of pressure rise and heat release are higher for biodiesels as compared to neat diesel. Many researchers observed shorter ignition delay in combustion for most of the renewable fuels.
