Definitions

  • the present invention relates to a system for determining the mass of gas admitted into an internal combustion engine of a motor vehicle.
  • the latter consists of heated sensitive elements subjected to cooling caused by the passage of fresh air entering the engine.
  • the flow meter then delivers information on the air flow entering depending on the amount of energy it must supply to the sensitive elements for them maintain at their operating temperature.
  • This value of the air flow is a quantity used by means of checking the operation of the engine, such as for example a engine control also called “CMM calculator”, in order to be able to control how it works.
  • CCM calculator engine control also called “CMM calculator”
  • the engine control computer uses the flow information of air entering it, to measure the amount of gas to be recirculated in the engine and this, generally according to the regime and the load thereof.
  • the flow meter is generally placed downstream of an air filter, at the inlet of the engine, i.e. on the clean air side thereof.
  • this flow meter gradually becomes clogged by deposit on its sensitive elements, for example particles or the like, in suspension in the air and not retained by the air filter.
  • drifts can be both positive and negative, depending the vehicle rolling profile, the air quality encountered, etc., and reach absolute levels which can be higher than 10%.
  • Such a bad dosage then results for example in a displacement Nox-particle compromise (emissions drift) of the vehicle, resulting in for example by reducing one of the pollutants at the expense of the other and which may lead to exceeding one of the two emission thresholds set by example in a regulatory manner.
  • the object of the invention is therefore to solve these problems.
  • FIG. 1 shows an internal combustion engine designated by the general reference 1 in this figure, this engine being by example a Diesel engine, associated with a gas recirculation circuit 2 exhaust at the inlet thereof, in which is interposed a valve 3 called "Recycling valve or EGR".
  • this engine being by example a Diesel engine, associated with a gas recirculation circuit 2 exhaust at the inlet thereof, in which is interposed a valve 3 called "Recycling valve or EGR".
  • This system ensures the recirculation of exhaust gases between the engine exhaust outlet designated by the general reference 4 and the entry thereof designated by the general reference 5.
  • This gas inlet is also associated with a designated intake by the general reference 6 in which a designated air filter is integrated by the general reference 7.
  • CCM computer engine control computer
  • This engine control computer is then suitable for example for regulate the amount of gas recirculated in the engine by acting on the valve EGR 3.
  • This computer is also connected at the input to designated means by the general reference 9 for measuring the pressure and the temperature of the gas admitted into the engine and to means 10 for measuring the mass of gas admitted into the engine.
  • the CMM 8 computer constitutes a processing unit of information which is ordered as will be described in more detail by the following, by means of triggering the changeover of its operation, between a first state known as learning and a second state known as registration.
  • volumetric efficiency is neither constant (function of engine, speed and load in particular), nor measurable, but can be determined by calculation.
  • the means for triggering the tilting of the operation of the information processing unit 8 between the first and the second states may for example include means of acquiring the mileage traveled by the vehicle and means for comparing this mileage to a threshold predetermined to toggle the information processing unit from its first state towards its second state according to the result of this comparison.
  • the learning phase takes into account the operation of each engine, which also improves reliability information by adapting the determination conditions to each engine.
  • step 11 it is determined whether the conditions are favorable for activation of the strategy described. If this is the case, the engine control computer 8 cuts the EGR function in step 12, i.e. cuts the gas recirculation exhaust by closing the EGR valve 3.
  • the information processing unit 8 records the mileage traveled by the vehicle and compares it to the predetermined threshold value, to find out if the mileage traveled by the vehicle is below this threshold.
  • step 14 the information processing unit ensures the acquisition of the air mass or the air flow from the flow meter 10 integrated in the engine intake line.
  • the information processing unit acquires the information engine rotation speed, inlet gas pressure and temperature gas admitted, from the corresponding sensors 8a and 9 to allow in 16, the calculation of the corresponding volumetric efficiency according to the equation described above and the storage of this different information in corresponding storage means 8c.
  • the information processing unit 8 switches in its second operating state known as registration.
  • step 18 the information processing unit recovers in the storage means 8c, a volumetric efficiency value as determined during the learning phase for the conditions corresponding engine operation.
  • the unit measures the air flow delivered by the flow meter 10.
  • this unit measures the engine rotation speed, and the pressure and the temperature of the admitted gases, which allows in step 21 to this unit to calculate the air flow admitted from the relationship described above.
  • the information processing unit compares the mass of gas calculated on the mass of air measured, as delivered by the corresponding measurement means, to determine an offset between these values and allow the storage of this offset and the registration of the information of mass of air delivered by the corresponding measuring means.
  • Volumetric efficiency and offset calculations performed during learning and adjustment phases may not be implemented by the information processing unit, only once the vehicle is driven by point of determined operation.
