Model for Predicting the Performance and Exhaust Gas Emissions of a Diesel Engine Fuelled by Diesel and Biodiesel B20. Simulation and Validation

Abstract

The increasing demand, price, and depletion of conventional Diesel fuel prompted extensive worldwide research into alternative energy sources for internal combustion engines. Among all the alternative fuel types, Biodiesel is considered a suitable fuel, and the most promising one for Diesel engines. This paper focuses on compression ignition engine fueled Diesel and Biodiesel B20. A model is proposed to providing realistic estimates of the engine performance, combustion characteristics and exhaust gas emissions for various engine speeds (1400 rpm, 2000 rpm, and 2400 rpm) at full load. Simulation results obtained by using the AVL BOOST v2013.2 code are presented. These results are validated against experimental data.
