Definitions

  • the present invention relates to a system for aiding regeneration of pollution control means integrated in an exhaust line of an engine thermal motor vehicle.
  • such means of depollution can for example comprise a NOx trap that is a system for reducing polluting emissions thermal engines of motor vehicles.
  • the engine is then associated with means for controlling its operation to switch it between standard mode operation poor and regenerative operation in rich mode, according to parameters different control of the operation of this engine.
  • the trap NOx stores these and when this trap is saturated, it triggers its regeneration by switching the engine to rich operating mode of destocking in which the engine produces reducers, such as for example CO and HC.
  • At least one parameter for controlling the operation of the engine that is to say at least one parameter relating to the injection of fuel into the engine (quantity, phasing, pressure, etc %) and / or at least one parameter of the motor supply air loop (air flow, recycling, turbocharger pressure, etc ).
  • the object of the invention is therefore to propose a system which makes it possible to solve these problems.
  • the subject of the invention is a regeneration aid system of pollution control means integrated in an exhaust line of an engine thermal motor vehicle, by tilting the motor between operation in lean mode and rich mode operation, depending on parameters different control of the operation of this engine, characterized in that has a Lambda probe placed at the outlet of the gases engine exhaust and means for correcting at least one parameter motor operation to regulate closed-loop, the wealth of these exhaust on a target value when the engine is running in rich.
  • this figure shows a regeneration aid system.
  • depollution means designated by the general reference 1 on this figure, integrated for example in an exhaust line 2 of a heat engine 3 of a motor vehicle.
  • This engine is also associated with air supply means designated by the general reference 4 and means for controlling its diet in fuel designated by the general reference 5, comprising for example means with a common rail for supplying the fuel injectors in the cylinders of this engine.
  • the depollution means comprise for example a NOx trap and the control means 6 are then adapted to switch the operation of the motor, between poor standard operation and in rich regeneration mode, according to different parameters of operation check of it.
  • Parameters 7 are then used to drive the motor in poor operation, while the parameters 8 are used to operate the engine in rich regeneration mode.
  • this system also comprises a Lambda probe ⁇ denoted by the general reference 9 in this figure, placed on the output side engine 3 exhaust gas, to measure the wealth exhaust gas from the engine.
  • This probe is connected to the control means 6 to ensure correction of at least one parameter for controlling the operation of the engine in order to regulate in closed loop this wealth of exhaust gases on a value target when the engine is running in rich mode.
  • the corrected engine operation check parameter can be for example the amount of fuel injected into the engine or the fuel injection pressure or the feed air flow of the engine.
  • the parameter corrected to enslave the richness of the exhaust can then be the injection pressure used in this ramp.
  • the duration of the injections are kept constant, this which makes it possible to adapt the total amount of fuel injected into the cylinders and to enslave wealth.
  • Another way to enslave wealth is to act on the amount of fuel injected during one of these injections and especially during the last injection of the series, so as not to disturb too much the operation of the engine in terms of torque, noise, etc.
  • This last injection is generally positioned between 10 ° and 120 ° after PMH.
  • control means 6 are therefore adapted to act on the means of supplying fuel or on the gas loop power supply, to enslave wealth to a target value and therefore to obtain the compromise mentioned above.
