Method for biodiesel blending detection based on internal mean effective pressure evaluation

A method for biodiesel blending detection in a internal combustion engine includes, but is not limited to a first evaluation of the internal mean effective pressure (IMEP) by means of measurements provided by a first sensor whose output is representative of the actual IMEP value, a second evaluation...

Summary:A method for biodiesel blending detection in a internal combustion engine includes, but is not limited to a first evaluation of the internal mean effective pressure (IMEP) by means of measurements provided by a first sensor whose output is representative of the actual IMEP value, a second evaluation of the internal mean effective pressure (IMEP) performed measuring fuel conversion efficiency (FCE), injected fuel quantity (Qfuel) and lower heating value LHV and carrying out the evaluation by means of the Electronic Control Unit (ECU) of the engine, and determining discrepancies of values obtained from the second evaluation compared with values obtained from the first evaluation.
