It may further comprise one or more other gas purification systems 7, for example a second catalyst 7, a nitrogen oxide trap 7, a particulate filter 7, etc. At the outlet of the pollution control device 7, the exhaust gases are discharged into the outside atmosphere in the direction of the arrow F2.

- an injection system for example a direct injection system which includes a common supply rail to the engines.
- cylinders and at least one fuel injector per cylinder adapted to inject the fuel directly into each of the cylinders.
- an air filter 8 which makes it possible to eliminate the dust contained in the air
- a flow meter 9 which makes it possible to determine the mass flow rate of air charge admitted in the engine 2
- an air intake flap 10, or throttle body 10 which regulates the flow admitted into the engine 2 by more or less obstructing the intake pipe 3.
- the heat engine 2 also comprises a turbocharger 1 1 whose compressor 12 is interposed in the intake duct 3 between the compressor 12 and the intake flap 10
- a heat exchanger 13 it is possible for a heat exchanger 13 to be arranged in the intake duct 3, between the compressor 12 and the intake flap 10, so that cool the compressed air by the compressor 12.
- the compressor 12 is driven by the turbine 14 of the turbocharger, which is interposed in the exhaust pipe 4 between the engine 2 and the depollution device 5.
- the heat engine 2 may comprise one or more gas recirculation circuits. intake exhaust (not shown), more particularly a so-called high pressure EGR circuit and / or a low pressure EGR (EGR) circuit, without impair the generality of the invention.
- the heat engine 2 produces a motor torque, said thermal torque C t , which results from the combustion of a mixture of fresh air (to which can be added recycled exhaust gases recycled to the intake) and fuel in well-defined quantities by a calculator of engine 2.
- the motorization device 1 also comprises a reversible electric machine 15, as illustrated in FIG.
- the electric machine 15 for example an alternator-starter 15 separate from the flywheel of the heat engine 2, and a rotary shaft 16 is coupled via transmission means 17 to a rotary shaft 18 of the engine 2, for example a crankshaft, is capable of operating in "engine” mode or in "generator” mode, under the supervision of a control box 19.
- the electrical machine 15 is an alternator which supplies an electric current for storage in a battery 20 of accumulators by taking a strong electrical torque C e ; in “motor” mode, it is instead powered by current previously stored in the battery 20 and provides an electric torque C e engine that is added to that C t of the engine to be transmitted to the wheels of the vehicle.
- the operating mode of the motorization device 1 is as follows: The depression of the accelerator pedal (not shown) of the vehicle by the driver is translated by a computer (not shown) into a torque setpoint C to be transmitted to the wheels of the vehicle.
- the torque C can then be obtained either in the form of a thermal torque, or in the form of electric torque, or in the form of a combination of the two.
- the value of the torque C is equal to the algebraic sum of the values of the thermal torque C t and of the electrical torque C e , the latter taking a positive value in "motor” mode and a negative value in "generator” mode. of the electric machine 15, the calculator performing the distribution according to different parameters of the vehicle and / or the device of motorisation 1.
- the catalyst may be equipped with means for determining a parameter representative of the temperature ⁇ of the exhaust gases passing through it, for example the temperature ⁇ of the catalyst itself, measured by a temperature sensor 21.
- FIG. 2 illustrates the various steps of a method of heating the catalyst 6 according to one embodiment of the invention, using a motorization device 1 as just described, in which the temperature ⁇ of the trap catalyst 6 up to a priming temperature 9 am o at which it has a predefined minimum treatment efficiency.
- the targeted efficiency can be of the order of 50%, and the corresponding initiation temperature can be close to 250 ° C as seen in Figure 1.
- the process begins with a step 100 of starting the vehicle. It can be materialized by the fact that the driver puts the ignition and requires a torque C for driving the vehicle, for example by pressing the accelerator pedal.
- the process continues, iteratively, by a step 200 of determining the temperature ⁇ of the catalyst 6, then by a step 300 of comparing said temperature with a temperature threshold 9 S , said preheating temperature, lower than the temperature boot 9 am o ⁇ for example, the preheat temperature is between 60 ° C and 100 ° C.
- step 400 of preheating the catalyst 400 in which the torque C necessary for driving the vehicle is entirely supplied by the electric machine 15. This is generally the case for several seconds after the vehicle is started when the vehicle has been stopped for a long time. On the other hand, it may be that after a short stop, the temperature of the catalyst at the restart of the vehicle did not have time to fall below the preheating temperature because of the thermal inertia. In this case, step 400 of preheating the catalyst does not take place.
- the heat engine 2 is not started. It does not produce a thermal torque. No fuel injection is performed in the cylinders. The heat engine 2 is rotated by the electric machine 15, and the successive cycles of compression of the air in the cylinders make it possible to increase the temperature at the exhaust and thus to heat the catalyst 6, until the reaching the preheating temperature 9 S. Particularly advantageously, this step 400 can be performed by completely closing the air intake flap 10. This results in an acceleration of the temperature rise of the catalyst 6.
- the process is directed to a step 500 for authorizing the starting of the heat engine 2.
- the torque C required for driving the vehicle can then produced by the heat engine 2, the electric machine 15, or a combination of both, under the supervision of the control box 19.
- step 600 to end heating of the catalyst, capable of raising the temperature ⁇ of the catalyst 6 from the preheating temperature 9 S to its light-off temperature 9 amo ⁇
- this step 600 may consist conventionally to achieve delayed combustion of fuel, compared to combustion carried out normal operation of the engine. In a manner known per se, it is possible, for example, to perform late fuel injections into the engine cylinders.
- step 400 of preheating the catalyst does not by itself make it possible to increase the efficiency of the catalyst.
- the efficiency being zero up to a temperature ⁇ of the order of 150 ° C, it remains zero until the end of the preheating step 400 because the temperature 9 S does not reach such a value, even in prolonging the preheating time.
- this preheating step advantageously makes it possible to shorten the duration of the heating of the catalyst up to its ignition temperature O amo by the known processes used in step 600, thus reducing the fuel consumption necessary for priming. catalyst at this stage.
- the invention is not limited to the embodiment just described.
- the method could be applied to any other exhaust gas depollution system requiring a minimum operating temperature for treating or storing pollutants, such as for example a nitrogen oxide trap 7 or a particulate filter 7, without departing from the scope of the invention.
