Definitions
- TITLE PROCESS FOR CORRECTING A RICHNESS OF A MIXTURE OF AIR AND FUEL SUPPLYING A COMBUSTION ENGINE
- the present invention relates to the field of internal combustion engines. More particularly, the subject of the invention is a method for correcting the richness of an air and fuel mixture supplying an internal combustion engine in the period between starting the engine and reaching the temperature of. operation of an oxygen sensor positioned in an engine exhaust line.
- the pollution control of internal combustion engines requires finer and finer regulation of the richness in order to meet increasingly stringent standards.
- These internal combustion engines are equipped with an exhaust line which incorporates one or more pollution control components such as a catalyst or a particulate filter and a richness sensor.
- the control command associated with internal combustion engines includes richness regulation based on measurements obtained by a so-called lambda probe or oxygen probe, present in the exhaust line. This probe measures the oxygen content of the burnt gases resulting from the combustion.
- Document FR-A-3052189 describes a method for adjusting the behavior models of actuators of air intake and fuel injection lines of internal combustion engine of a motor vehicle.
- the motor is fitted with piloted actuators.
- the adjustment of the behavior models is done simultaneously for the actuators of the air intake and fuel injection lines at at least one engine operating point only as a function of an air flow in each cylinder and 'a wealth instruction.
- the adjustment is based on a difference between an actual flow measurement and a flow estimate model in each cylinder.
- the adjustment is made according to a difference between a real richness measurement and the richness setpoint.
- the problem at the basis of the invention is to correct the richness of the air / fuel mixture of a cold internal combustion engine when a richness sensor, present in the exhaust line of this engine, is inoperative in not yet having reached its operating temperature, which does not allow the richness regulation loop to be activated.
- a richness setpoint is determined, and from this setpoint a quantity of fuel to be injected into the internal combustion engine,
- the oxygen sensor is heated, characterized in that, as a function of the value of this temperature representative of the thermal state of the engine, a corrective factor to be applied to the quantity of fuel to be injected determined from the richness setpoint and we apply this corrective factor until the oxygen sensor has reached operating temperature.
- the technical effect is to obtain an adjustment of the real richness of a mixture of air and fuel supplying an internal combustion engine according to the thermal state of the engine when the richness regulation is inactive.
- the time elapsed between the last stop of the engine and the start of starting is calculated and the method is activated if this duration is greater than a determined engine stop duration threshold for which it is considered that the engine is sufficiently cooled. .
- the determined engine stop duration threshold for which it is considered that the engine is sufficiently cooled is greater than one hour.
- the corrective factor is determined from a map establishing this factor as a function of the temperature representative of the thermal state of the engine.
- the mapping includes several corrective factors, each of these factors establishing the correction for a determined temperature range representative of the thermal state of the engine.
- the temperature representative of the thermal state of the engine measured during start-up is stored, and when the oxygen sensor has reached its operating temperature, a current corrective factor is determined from the difference between the setpoint of richness and richness determined from the measurement of the oxygen sensor, and the existing corrective factor associated with the temperature measured is replaced in the mapping by this current corrective factor.
- the time elapsed between the start of starting and the oxygen sensor reaching its operating temperature is measured, the time elapsed between the last stop of the engine and the start of starting, the replacement of the factor is calculated. corrective action being authorized only if the time elapsed between the start of start-up and when the oxygen sensor reaches its operating temperature is greater than a threshold for the time the oxygen sensor is put into operation and if the time elapsed between last stop of the engine and the start of the start is greater than a determined engine stop duration threshold.
- the temperature representative of the thermal state of the engine is the engine coolant or the lubricating oil.
- the invention also relates to an engine control unit, characterized in that it comprises the means of acquisition, processing by software instructions stored in a memory as well as the control means required to implement the method according to one any of the variants described above.
- the invention also relates to a vehicle comprising an internal combustion engine connected to an exhaust line equipped with an oxygen sensor, and comprising such an engine control unit.
- FIG 1 shows a flowchart of the method for correcting the richness of the air / fuel mixture supplying an internal combustion engine according to the present invention.
- FIG 2 illustrates an example of a mapping establishing the richness correction factor as a function of a temperature range representative of the thermal state of the engine.
- FIG. 1 shows an engine control unit 7 in charge of the operation of an internal combustion engine 1 opening onto an exhaust line 2 for evacuating the exhaust gases from the internal combustion engine 1.
- the present invention is more particularly intended for an internal combustion engine with controlled ignition, in particular with gasoline fuel or containing gasoline.
- the present invention can also be applied to a compression ignition engine.
- the internal combustion engine can be integrated into a motor vehicle.
- the control unit 7 comprises the means of acquisition, processing by software instructions stored in a memory as well as the control means required to implement the method of the invention detailed below.
- the internal combustion engine 1 comprises actuators 3 managing the air loop such as for example an air metering butterfly valve and actuators 4 managing a fuel supply system.
- the exhaust line 2 comprises a pollution control system 5 and an oxygen sensor 6, which is operational only when it reaches a minimum operating temperature.
- the engine control unit 7 comprises an air loop control control module 8.
- the air loop control control module 8 sends an intake air setpoint to the air loop actuators 3 of the engine 1 to internal combustion and a fuel setpoint to the actuators of the fuel supply system 4 of the internal combustion engine 1.
- the engine control unit 7 also includes an adaptation module comprising an adaptive air loop submodule 11 and an adaptive model submodule 10 for injecting fuel into the engine 1.
- the adaptive air loop submodule 11 communicates with the air loop actuators 3 of the engine 1 and the adaptive model submodule 10 for fuel injection into the engine 1 communicates with the actuators of the engine 1 system. fuel supply 4 to engine 1.
- the engine control unit 7 also comprises a module 13 for regulating the richness of the air / fuel mixture, a selector 9 being able to alternate between a first position when the oxygen sensor 6 present in the exhaust line 2 is operational (position of the selector cursor 9 shown in dotted lines in FIG. 1) and a second position when the oxygen sensor 6 is not operational (position of the selector cursor 9 shown in solid lines in FIG. 1).
- the engine control unit 7 also includes a module for determining a richness setpoint 14 of the air / fuel mixture.
- This module communicates with the actuators of the fuel supply system 4 of the engine 1 by sending a richness setpoint, Cr, of the air / fuel mixture to the actuators of the fuel supply system. 4 of engine 1.
- This richness setpoint, Cr makes it possible to determine a quantity of fuel to be injected.
- the selector 9 communicates with the actuators of the fuel system 4 of engine 1 by also sending a corrective factor, Iron, for the richness of the air / fuel mixture to the actuators of the fuel system 4 of engine 1.
- a corrective factor, Iron for the richness of the air / fuel mixture will come from the richness regulation module 13 (first position) or from the richness correction module 12 (second position).
- This corrective factor, Iron makes it possible to modify the quantity of fuel to be injected determined from the richness setpoint, Cr.
- the engine control unit 7 also comprises a richness correction module 12 which will be subsequently more precisely detailed for the implementation of the method of the invention for the correction of the richness of the air / fuel mixture supplying the engine 1 during 'a start-up, during the phase when the oxygen sensor 6 is not operational.
- the richness correction method according to the invention takes place when the internal combustion engine 1 is started, between the start-up time and the subsequent time when the oxygen sensor has reached its operating temperature, which makes it operational and then enables the richness regulation module 13 to be activated.
- module 14 determines a richness setpoint, Cr, and the heating of the oxygen sensor is activated. However, as long as the oxygen sensor 6 is not operational, the selector 9 is positioned in its second position. A richness correction factor, Iron, is then supplied by the richness correction module 12.
- a temperature T representative of the thermal state of engine 1 is measured.
- This temperature T can be that of the coolant or also of the engine lubricating oil.
- This temperature T is supplied to the richness correction module 12, which determines, as a function of the value of this temperature T representative of the thermal state of the engine 1, the corrective factor, Iron, to be applied to the quantity of fuel to be injected determined from of the richness setpoint Cr.
- This corrective factor, Iron, determined by the richness correction module 12, is applied until the oxygen sensor 6 has reached its operating temperature.
- the selector 9 switches to its first position and the corrective factor Iron to be applied to the quantity of fuel to be injected determined by the richness setpoint Cr is now supplied by the regulation module 13 of richness which receives the measurement from the oxygen sensor 6.
- the richness correction factor Fcr1 is selected. If the temperature T is in the temperature range between T1 and T2, or between T2 and T3, or between T3 and T4, respectively, the selected richness correction factor will be Fc2, Fc3, Fc4 respectively. Finally, if the temperature T is greater than the maximum temperature T4, the richness correction factor Fcr5 is selected.
- the correction method is activated if this time elapsed between the last stop of engine 1 and the start of starting is greater than a determined engine stop duration threshold, duration threshold for which it is considered that the engine is sufficiently cooled.
- This engine stop time for which it is considered that the engine is sufficiently cooled can be a duration greater than 1 hour. If the time elapsed between the last stop of motor 1 and the start of starting is less than this time, it is possible to apply a correction factor equal to 1 (neutral).
- the temperature T representative of the thermal state of the engine (1) measured during start-up is stored.
- the richness regulation module then being active, a current corrective factor is determined from the difference between the richness setpoint Cr and the richness determined from the measurement of the oxygen sensor 6, and the existing corrective factor associated with the temperature T measured by this current corrective factor is replaced in the map.
- the time elapsed between the start of the start-up and the oxygen sensor 6 reaching its operating temperature is measured and the time elapsed between the last stop of the engine 1 and the start of the start-up is calculated.
- the operating time threshold can be between a few seconds, for example 5 seconds to a few minutes, for example 5 minutes, while the engine shutdown time threshold is greater than 1 hour. Indeed, it takes a few seconds to heat the probe 6 if the drying of the line is not necessary, while it takes a few minutes if it is necessary to wait for the line to dry, in the case where the probe 6 may break in contact with liquid water when heated.
- the learning function makes it possible to bring the richness closer to the desired value engine to engine and thus makes it possible to reduce pollutant emissions.
- the invention makes it possible to reset the richness of the air / fuel mixture when cold and only when cold, when the richness regulation is not activated because the oxygen sensor is not operational.
- the invention therefore makes it possible to reduce pollutant emissions during this phase when the richness regulation is not activated.
- the invention not being based on a physical model, can be generalized to all systems and makes it possible to readjust any dispersion that could lead to a wealth gap.
