  • Abstract:
  • In this study mineral diesel fuel, biodiesel (Pongamia), and methanol– biodiesel blends were tested in a 4 stroke single cylinder direct-injection diesel engine to investigate the combustion characteristics and particulate emissions of the diesel engine under six engine loads at the maximum torque engine speed of 1500 rpm. Test has been conducted on 200 bar fuel injection pressure. BTE, BSFC, emissions like CO, HC and NOx are measured. Overall, biodiesel-methanol diesel blends show higher brake specific fuel consumption than mineral diesel. As methanol proportions in blends increase, NO emissions increase, while CO emissions are reduced. Also, biodiesel-diesel blend with 10% of methanol is more effective than biodiesel blend with 20% for reducing CO emissions. Blend B20 gave better outcomes than other blends, but at little higher BSFC than diesel. In all biodiesel blends drop is witnessed in CO, HC but has more NOx emission. From investigation it is concluded that bio-diesel methanol and diesel blends can be used securely as substitute fuel to substitute diesel without any alteration in engine.
