Abstract

Within the cooperative research project DAX605 between GM Powertrain Europe and Istituto Motori - CNR, the capability to develop a method (economic and simple) for on-board biodiesel blending detection was studied. The method is based on the direct measurement of the Indicated Mean Effective Pressure (IMEP). The present research report summarizes the main results of this activity. The study was carried out on a 2.0L 4-cylinder “torque-controlled” Euro 5 diesel engine for passenger car (PC) application. This engine, equipped with instrumented glow plug for combustion closed loop control, represents the state of the art of the diesel engine control technology. Two biodiesels were chosen for the experiments: a Rapeseed-Methyl-Ester (RME) and an aged RME, while the conventional diesel fuel was an European (EU) certification diesel fuel. Results indicate generally a good response in blending detection of the method. However, in order to attain an acceptable accuracy, a pre-calibration appears necessary.
