Researches Concerning Some Combustion Characteristics of a Biodiesel Type Fuel in a D.I. Agricultural Diesel Engine 2007-01-0075

The paper presents some results concerning the use of a Biodiesel type fuel in a direct injection (D.I) Diesel engine. The fuel was produced from waste vegetable oil, collected from the local McDonalds' branch. The engine was fueled with a blend containing 50% Biodiesel and 50% Diesel fuel (B50, Biodiesel blend). The tests were developed on a D-110 Diesel engine (S/D= 130/108 mm, ε = 17, three in line cylinders); the output power, torque, BSFC, combustion pressure, pressure rate and autoignition delay were measured and the heat release rate was calculated. We noticed a slight decrease of the power indices when the Biodiesel type fuel was used (output power and torque) and also of the peak combustion rate. The peak heat release rate decreased, while the autoignition delay has decreased by 2…4° CA.
