Impact on performance, combustion and exhaust emission characteristics using mahua oil and diesel blends

Abstract Today’s energy scenario has propagated and enhanced the research in the non-conventional, renewable and environmentally friendly fuels. The increasing cost of conventional fuels has motivated researchers to look at renewable alternatives for use in internal combustion engines. When compared to other seed fuels like ethanol and essential oils, mahua oil has comparable low viscosity, boiling temperature, and flash point. The present paper discuss on the experimental investigations carried out using the blends of Mahua oil and diesel. The blends are prepared on a volume basis and designated as MO10, MO 20, MO 30 and MO 40. It is observed that BTE increases for MO10 and MO20 blends by 2.7 and 5.8% respectively. Whereas there is a decrease in CO, HC and smoke emission compared to diesel. The NOx Emission levels for all Mahua oil blends increased due to rise In-cylinder pressure.
