Analysis of combustion, emission and performance attributes of hemp biodiesel on a compression ignition engine

摘要

The increasing pollution problems caused by conventional fuels and fuel scarcity are forcing the scientists all over the world to look for sustainable fuel alternatives. The suitability of hemp biodiesel derived from non-edible industrial grade hemp (Cannabis sativa L.) seed as a biofuel in C.I engines is discussed in this paper. The performance, emission and combustion attributes of different hemp biodiesel combinations are tested on a Kirloskar VCR engine at a standard compression ratio 17.5:1 and the outcomes are contrasted with those of standard diesel fuel. Hemp biodiesel blends exhibit an average increment of 7.35% in the mechanical efficiency in comparison to neat diesel. Hemp biofuel blends also results in a moderate decrement in CO and HC emissions by 20.83% and 24.5% accordingly at peak load. The experimental findings show the suitability of hemp biodiesel blends as a nature-friendly alternate fuel.
