Definitions

  • the invention relates to internal combustion engines and, more particularly in such engines, a method and a system for calculating the mass of fresh air contained in a cylinder.
  • the volume or the weight of the fuel can be known, with relative precision, by the duration of injection of the latter in the case of an injection engine.
  • several methods are used such as the measurement of the air flow in the intake manifold to the different cylinders, the measurement of the pressure in the intake manifold combined with the measurement of the engine speed. , the measurement of the opening angle of the intake throttle valve combined with the measurement of the engine speed.
  • An object of the invention is therefore to implement a method for calculating the mass of fresh air contained in each cylinder of an internal combustion engine from pressure measurements inside each cylinder.
  • Another object of the invention is a system for calculating the mass of fresh air contained in each cylinder of an internal combustion engine.
  • the applicant carried out direct measurements on the engine test bench.
  • Direct measurements on the engine test bench consist of running the engine at a constant speed and measuring (U 90 ° -U 40 ° ) for different measured values of the mass of fresh air injected.
  • This mass of fresh air m af resulting from the calculation corresponds to the current cycle, is used for the calculation of the injection time of the following cycle and this for each cylinder, the ignition angle and more generally of all the variables set by the filling of the cylinders.
  • FIG. 2 The system which makes it possible to implement the method according to the invention will be described (FIG. 2) in its application to a four-cylinder engine C1, C2, C3, and C4 which are supplied with air by an intake manifold 20 common to four cylinders.
  • the inlet of this intake manifold is controlled by a butterfly valve 21 linked to the accelerator.
  • this conduit 20 is subdivided into four intake pipes T1, T2, T3 and T4 each leading to an intake valve SA1, SA2, SA3 and SA4.
  • Each manifold is associated with a fuel injector I1, I2, I3, and I4.
  • Each cylinder has a spark plug B1, B2, B3, or B4 for igniting the detonating mixture and a pressure sensor CP1, CP2, CP3, and CP4.
  • the burnt gases are evacuated to an exhaust pipe TE1, TE2, TE3, and TE4 by an exhaust valve SE1, SE2, SE3 and SE4, the four pipes joining to form a conduit for exhaust 22.
  • the angular position of the motor shaft is identified using a toothed wheel 25 secured to the motor shaft and associated with a detector 26, the output terminal of which is connected to an input of a computer 27.
  • the computer conventionally supplies the control signals of the injectors I1 to I4 and of the spark plugs B1 to B4 as a function of various parameters such as the engine speed, the position of the accelerator, that of the throttle valve 21.
  • the signals supplied by the pressure sensors CP1 to CP4 are applied to the computer 27 which performs, for each cylinder, the calculations defined by the method described above.
  • the values of ⁇ 1 and ⁇ 2 are different and the signals from the pressure sensors are only taken into account for the values ⁇ 1 and ⁇ 2 by appropriate sampling.
  • the fuel mass m c of each cylinder for a given cycle is determined by the computer 27 from the value of m af calculated for the previous cycle, this is what fixes the opening time of the injectors I1 to I4.
  • the pressure sensors CP1 to CP4 replace the pressure sensor of the intake manifold or the flowmeter, the information of which is usually used to control the engine via the computer 27.
