Abstract:

The rapid increase of diesel engines and the diminishing of diesel fuel creates a challenge for researchers to find an alternative fuel. The present experiment is performed on a 3.5kW diesel engine. Here, diesel is replaced with pure lemongrass oil (LGO) of 10%, 20%, and 30% by volume with diesel. The specific fuel consumption (SFC) of LGO blends shows an increase compared to diesel, due to the lower heating value for LGO blends. On the other hand, LGO blends shown lower emissions of NOX, due to the lower peak flame temperature. When compared to the other samples, the LG30 gives a maximum reduction in NOx emissions; of 10.33%. When compared to biodiesel blends, diesel fuel shows a significant increase in the Net Heat Release rate (NHR).
