Definitions
- the present invention relates to a system for assisting the regeneration of a particulate filter integrated in an exhaust line of an engine, in particular of a motor vehicle.
- soot regeneration temperature is around 550 to 600 ° C. However, these temperatures can only be reached for very heavy load operating conditions of these motors.
- these particle filters can be combined with oxidation catalysts arranged upstream of them.
- the subject of the invention is a system for assisting the regeneration of a particulate filter integrated in an exhaust line, in particular of a motor vehicle, of the type comprising means for injecting fuel into the minus some of the engine cylinders during the expansion phase thereof, to cause an increase in the temperature of the exhaust gases thereof in order to assist in the regeneration of the filter, characterized in that the means for injection are adapted to cause several injections of fuel, in calibrated quantities, distributed over time during the expansion phase, in that the engine is associated with a turbocharger and in that the system includes pressure regulation means turbocharger boost to reduce the amount of air entering the engine.
- Fig.1 shows a block diagram illustrating the structure of a system for assisting the regeneration of a filter according to the invention.
- FIG. 1 shows a system for assisting the regeneration of a particulate filter integrated into an exhaust line of a diesel engine, in particular of a motor vehicle.
- the engine is designated by the general reference 1 and the exhaust gases from the latter are caused to circulate in an exhaust line designated by the general reference 2.
- This exhaust line is possibly associated with a turbocharger designated by the general reference 3 and the gases therefore pass into this turbocharger and more particularly in the turbine portion thereof
- the engine is also associated with a fuel supply system designated by the general reference 5 in this figure, this supply system comprising for example a common supply system for all the cylinders of the engine, of the "Common Rail" type, comprising for each cylinder of the engine, an injector with electrical control, for example, such as that designated by the general reference 6 in this figure
- the particulate filter designated by the general reference 4 can also be associated with an oxidation catalyst designated by the general reference 8 in this figure, to aid its regeneration and placed upstream of this filter in the exhaust line.
- the fuel injection means are adapted to cause several fuel injections in calibrated quantities, distributed over time during the expansion phase of at least some of the cylinders. This then makes it possible to increase the temperature of the gases. exhaust to assist in the regeneration of the filter without significant repercussion on the torque supplied by the engine as illustrated in Figures 2, 3 and 4
- the objective is to prolong the combustion for as long as possible, without modifying the engine torque, in order to obtain higher temperatures of the gases in the combustion chamber at the time of opening the exhaust valve to increase the temperature of the soot and trigger its combustion in the particulate filter
- the fuel can be injected in calibrated quantities into at least some of the cylinders, for example in three stages, namely, a first injection known as a 1 * 1 pilot identical to 11, a second injection P2 which generates the thermodynamic conditions favorable to a third injection l'3 and provides part of the torque requested by the user.
- injection l * 3 generates the additional torque making it possible to reach that required by the driver of the vehicle, increases the temperature of the exhaust gases by continuing combustion late during the expansion phase and can also generate, depending on its setting, unburnt hydrocarbons which will ensure an additional increase in the temperature of the gases, thanks to a catalytic combustion in the catalyst 8 placed upstream of the particulate filter.
- the quantity of fuel injected during injection l'3 is therefore much greater than that injected during injection l'2 for the operating points at low engine load, greater than or equal to this for intermediate loads and less than this for operating points at high engine load, injection l'3 taking place after injection l'2 with an angular offset that can range from 15 to 150 ° crankshaft depending on the operating point.
- This new setpoint then decreases the air flow entering the engine, which has the effect of increasing the richness of the exhaust gases and also increases the temperature.
- this instruction can for example be delivered by the central information processing unit 7 to the turbocharger designated by the general reference 3 in FIG. 1.
- the regeneration aid system according to the invention makes it possible to create the thermal levels necessary for the combustion of soot in the filter without modification of the engine torque.
- thermal levels are reached at iso-torque by an extension of the combustion in the engine cycle thanks to successive multiple injections of fuel during the expansion phase of at least certain cylinders thereof, these injections being able to be associated with catalytic combustion of hydrocarbons generated by these multiple injections into a catalyst and by a specific instruction for regulating the boost pressure of a turbocharger associated with the engine.
