Abstract

In the 21st century one of the biggest challenges is high demand for fossil fuel sources because of the rapid growth of automotive industry. The reduction of fossil fuel sources and environmental degradation are the major problems the world facing in present scenario. Since the petroleum fuel sources are limited and exhaustible in nature, a lot of efforts are needed to reduce the dependency over them. Because of all these reasons, it is very essential to search for renewable environment friendly alternate fuel for replacement of diesel fuel in diesel engines. So, in this regard, an attempt is made by using the blends of hemp biodiesel in a computerised water-cooled, single cylinder, four stroke diesel engine. As per ASTM standards, the determined fuel properties for hemp biodiesel and all its blends are found comparable with diesel fuel. The combustion characteristics of diesel engine fuelled with hemp biodiesel blends are determined and compared to diesel fuel. As per combustion characteristics determined, the maximum cylinder pressure, maximum net heat release rate and maximum cumulative heat release rate fuelled with blends of hemp biodiesel are found comparable with that reached by diesel fuel at full load condition.
