Abstract :

This paper presents experimental results of combustion and exhaust emission characteristics of rapeseed oil and its blends with diesel. A 10 HP, 4 stroke 4 cylinder direct injection diesel engine was tested with rapeseed oil biodiesel and its blends to compare with conventional diesel fuel for different parameters. For this experimental work, different fuels namely diesel, 80:20, 60:40, 40:60 and 20:80 (v/v) blends of diesel fuel: Rapeseed Oil Biodiesel and neat Rapeseed biodiesel were prepared and tested for the performance and exhaust emission. Various parameters like Specific Fuel consumption, Brake Thermal Efficiency, Exhaust Gas Temperature, Smoke density, Carbon monoxide emission (CO) and Total unburned hydrocarbon emission (HC) were measured. The differences in the performance and exhaust emissions of these fuel blends when working with neat rapeseed oil biodiesel or its bio–diesel blends were compared.
