Rapeseed Methyl Ester

An alternate biodiesel fuel Rapeseed Methyl Ester (RME) has been evaluated for diesel engine Combination Electronic Unit Pump (CEUP) fuel injection system. Pressure wave modeling of CEUP high pressure fuel pipeline using viscous damped wave equation has been done in MATLAB at various operating conditions of diesel engine. Finite Difference method has been used to model and simulate wave equation at eleven equidistant locations along fuel pipeline. Results show increase in pressure, density, acoustic wave speed and bulk modulus amplitudes with RME fuel as compared to conventional diesel fuel.
