Dynamical behavior of rapeseed oil and methyl ester of rapeseed oil during high-pressure injection

Abstract

Fuels' physical properties such as density, viscosity, speed of sound and bulk modulus have and important influence on the engine performance. This work will study the behavior of the rapeseed oil and methyl ester of rapeseed oil during high-pressure injection. Several aspects of the injection and combustion process will be analyzed in order to try to find out in what manner these aspects are influenced by the above-mentioned fuels' characteristics and also by different operating regimes. In such a way, some features of the technical efficiency of the two non-conventional diesel fuels will be determined. As a reference, it will serve the results from testing classical diesel. © Owned by the authors 2012.
