    Abstract: An atmospheric pressure estimating apparatus which estimates an atmospheric pressure applied to a calculation of control parameters of an internal combustion engine, is provided. An estimated intake air control valve passing air flow rate is calculated based on the estimated atmospheric pressure, the detected intake pressure, and the detected intake air control valve opening. The estimated atmospheric pressure is updated so that the estimated intake air control valve passing air flow rate coincides with the detected intake air control valve passing air flow rate. The estimated intake air control valve passing air flow rate is calculated using the updated estimated atmospheric pressure. The update of the estimated atmospheric pressure and the calculation of the estimated control valve passing air flow rate are sequentially performed. Consequently, the estimated control valve passing air flow rate follows the intake air flow rate, and the estimated atmospheric pressure follows the atmospheric pressure.

    Abstract: An engine air supply control method relating to a turbocharged engine including an intake manifold (20) which is disposed downstream of the compressor of the turbocharger (14) and an exhaust manifold (22) which is disposed upstream of the turbine of the turbocharger (14). The method includes determining the mass air flow supplying the engine and/or the pressure in the intake manifold (20) and the temperature in the exhaust manifold. The pressure in the exhaust manifold (22) is determined as a function of the pressure in the intake manifold (20), the engine speed, the temperatures in the cylinders (4) and in the exhaust manifold (22), the pressure in the intake manifold (20) being optionally determined from the mass air flow. Inversely, the pressure in the intake manifold.

    Abstract: Method of acquisition and processing of an intake pressure signal in an internal combustion engine without an intake manifold; the internal combustion engine having at least one cylinder that receives fresh air through an intake duct, which is controlled by a butterfly valve and is provided with a pressure sensor connected to an electronic control unit. The acquisition and processing method provides for the following steps: measuring, via the pressure sensor, the instantaneous induction pressure at a plurality of different crank angles distributed over an engine cycle; storing, during each engine cycle, the instantaneous induction pressures in a fast acquisition buffer of the electronic control unit; and determining, at the end of each engine cycle, the mean induction pressure in the engine cycle by calculating a mean of the instantaneous induction pressures previously stored in the fast acquisition buffer of the electronic control unit.
