Combustion modeling of a Common Rail multi-injection diesel engine fueled with diesel and biodiesel

Abstract

In recent years, the use of biofuels in the conventional diesel fuel injection system has been interested by the scientists, fuel producers as well as consumers. However, there has a few of using biodiesel research on Common Rail (CR) diesel engine. This paper descripts a combustion model of a CR multi-injection diesel engine using blends of palm oil derived biodiesel and diesel. The engine combustion parameters such as peak pressure, heat release rate and ignition delay were measured and computed, the mass fraction burn at 50% (MFB50) was also investigated in this paper.
