Abstract (en)

[origin: WO2009001015A2] As the lack of pertinence has been assessed for various models developed for satisfying a need for the efficient operation of diesel engines (5), the invention has shown that the most important problem originated from the mass storage (?M) of the gases mixed at the inlet of the engine. The idea developed in the invention was to measure this mass (M). The measure is preferably carried out in the inlet manifold (2). By doing so and particularly by measuring the temperature (T2) and the pressure (P29 at this point, it is possible to take into account the phenomena of mass build-up, of losses of dynamic load and static compression, and thus of the flow, that interfere with the expected efficiency of the engine.
