Definitions

  • the invention relates to a control method for the regeneration of a particulate filter equipping a power train of a vehicle.
  • the heterogeneity of combustion processes in lean-burn engines, especially in diesel engines, has the effect of generating carbon particles, which can not be burned effectively in the engine. This is explained by example by the appearance, at the exit of the line exhaust, black smoke. This phenomenon is a source of pollution that we seek to reduce.
  • Regeneration devices driven by a calculator allow you to periodically burn particles trapped in the filter and to avoid the clogging of the latter.
  • the soot particles are essentially carbonaceous elements, and their combustion consumes oxygen to form gas carbonic.
  • Triggering the regeneration of the filter is controlled by a calculator that determines if the regeneration must take place and when it is in course, if it can continue. For that, the calculator receives information about the operation of the vehicle. These informations include for example the temperatures of the liquid engine cooling, upstream gases and downstream of the particulate filter, the speed of the vehicle, the mass of soot accumulated in the filter particles and the distance traveled since the last regeneration.
  • the calculator checks conditions on these information and only triggers regeneration if all conditions are satisfied.
  • the regeneration is maintained, although some conditions are no longer satisfied for a period below a predetermined threshold, of the order of one to two minutes. If at least one condition is no longer satisfied for a duration greater than said threshold, then the regeneration process is interrupted.
  • the operating conditions of the engine are modified to increase the temperature of the gases exhaust before they pass through the filter particles. These changes often relate to fuel injection, which can be delayed for at least one cylinder of the engine. These modifications increase fuel consumption and also the amount of fuel that dissolves in the oil the engine, passing through the space between the cylinder and the piston.
  • the invention aims to object a method of controlling a system of motorization comprising a particle filter receiving engine exhaust to restrain the particles of the exhaust gases, the process handling information and controlling the engine to obtain the regeneration of the particulate filter when necessary, characterized in that the method establishes an estimate of the dilution rate of fuel in oil, the process allowing the regeneration if the estimate of the dilution ratio is less than a predetermined dilution threshold.
  • the variation of the dilution ratio is evaluated by a first representative function evaporation, fuel when no regeneration of the particulate filter is in progress, and by a second function when a regeneration Particle filter is in progress.
  • a first representative function evaporation fuel when no regeneration of the particulate filter is in progress
  • a second function when a regeneration Particle filter is in progress.
  • the second function is the sum of the first function and a third function.
  • the variation in the rate of dilution is evaluated according to the speed of rotation of the motor and a variable representing the engine load. Indeed these variables are very influential on the variation of the dilution rate.
  • variable representing the motor load is a flow of injected fuel.
  • the first and the second function are stored as mappings.
  • the functions can be implemented from simple way, after a phase of development of the motorization system.
  • a motorization system implementing the method according to the invention and shown in FIG. 1, comprises a supercharged Diesel engine 1 by a turbocharger 2 and whose gases exhaust are treated by a particulate filter catalytic converter 3.
  • Engine 1 is supplied with air by a air circuit comprising an air intake 11, a compressor 12 of the turbocharger 2, a pipe of discharge 13 and an intake manifold 14 opening into engine combustion chambers 1, with only one chamber 15 being shown.
  • a gas recycling circuit exhaust has a stitching 18 on the tubing exhaust, a selector valve 19 orienting the exhaust gases to the discharge pipe either through a cooler 20, or through a direct driving 21.
  • a calculator 24 receives information on the operation of the motorization system and command the engine 1. It implements in particular the process according to the invention.
  • the calculator 24 determines whether the regeneration must be piloted or not. For that, he establishes whether certain criteria are met. When all criteria are met, a control signal from the regeneration is delivered. The calculator maintains the control signal of the regeneration during a predetermined duration D1 after at least one criterion is no longer satisfied.
  • the calculator takes into account a criterion on the dilution rate Pdil of fuel in the engine oil.
  • the dilution ratio is estimated by the calculator, and if the rate estimate Pdil dilution is greater than a threshold of dilution Sdil predetermined, the criterion is no longer satisfied.
  • step initialization 30 the estimation of the dilution ratio Dpil is initialized to either a null value if the oil is new, ie to a value previously estimated and memorized.
  • step 32 point to a step 32 if no regeneration is in progress, or to a step 33 in the case opposite.
  • step 32 an estimate of variation the dilution ratio dPdil is calculated by the opposite of the product of a function Evapap of evaporation of the fuel and a time step dt.
  • the function Fevap is calculated from a stored map, depending on the speed of rotation N and the flow rate of fuel Qc.
  • step 33 the variation estimate the dilution ratio dPdil is calculated as step 32 with additionally adding the product of a regeneration function Grégé of a time step dt.
  • the Grégé regeneration function is also calculated from a stored map, in depending on the speed of rotation N and the flow rate of fuel Qc.
  • the new dilution ratio Pdil (n) is calculated by adding to the dilution rate at the time step previous Pdil (n-1) rate variation estimate Dilution dilution.
  • step 35 and 36 it is ensured that the rate of dilution will not become negative. Then at the stage 37, the dilution ratio Pdil is compared with the threshold of dilution Sdil predetermined: if it is higher, the criterion is not satisfied and regeneration is prohibited (step 38). Otherwise, a regeneration is allowed (step 39).
  • step 40 the flow of the step is awaited. time before proceeding to a new step of calculation, resuming at step 31.
  • the invention is not limited to the mode of realization which has just been described only in as an example. We can use other variables representative of the engine load, such as airflow or air pressure intake.
