Abstract
The invention relates to a method for adjusting injection, combustion and/or post-treatment parameters of an internal combustion engine with auto-ignition, characterized in that it comprises a step of determining the content and the type of biofuel present in the fuel feeding the injection system. The invention also relates to a motorization system and equipment for implementing this method, implementing a sensor for determining the content and the type of biofuel present in the fuel feeding the injection system.
Claims16
A method for adjusting injection, combustion and/or post-treatment parameters of an internal combustion engine with auto-ignition including:
- determining the content and type of biofuel present in the fuel feeding the injection system using a spectroscopic sensor to measure values of near infrared spectra of the fuel and by introducing the measured values into universal mathematic and statistic models to extract information relative to the content and/or type of biofuel present in the fuel;
- and
- storing this information and recording in a memory a history of the determined content and of biofuel.
A motorization system including:
- an internal combustion engine with auto-ignition;
- a fuel tank;
- a pump gauge module;
- at least one fuel filter;
- an engine fuel supply circuit and a return circuit to the fuel tank;
- and
- a close-infrared spectroscopic sensor positioned on the fuel circuit for determining the content and type of biofuel present in the fuel.
