Definitions

  • the invention relates to the management of the cooling of an engine system equipped with a partial exhaust gas recirculation device, in particular of a diesel engine system.
  • the invention can thus find an application in the automotive field.
  • An engine system is generally cooled by a cooling circuit.
  • an internal combustion engine makes it possible to transform the initial energy supplied by the fuel into movement of the crankshaft. Part of the energy is transformed into thermal energy distributed in the exhaust gases and in losses at the walls of the combustion chamber. Combustion can lead to chamber temperatures of the order of 800°C, whereas the cylinder heads of combustion chambers, when they are made of aluminum alloy, are generally designed to withstand temperatures of 250°C maximum only. To limit the temperatures to acceptable values for good thermomechanical behavior of the motor, it is necessary to evacuate sufficient calories to the environment.
  • the cooling circuit thus prevents the engine from overheating.
  • this circuit can make it possible to relatively quickly ensure an optimal thermal level of one or more other components of the powertrain, to contribute for example to the heating performance of the passenger compartment.
  • An EGR (Exhaust Gas Recirculation) or EGR (Exhaust Gas Recirculation) device thus makes it possible to inject fresh air mixed with exhaust gases into the combustion chamber. This recovery of exhaust gases can reduce nitrogen oxide (NOx) emissions.
  • NOx nitrogen oxide
  • Such a cold loop system thus involves two separate cooling circuits connected to each other.
  • an EGR cooler also called an EGR exchanger
  • an EGR exchanger designed to cool the exhaust gases intended to be reintroduced into the engine intake, into a cooling circuit of the engine itself.
  • a so-called hot loop cooling circuit can comprise an EGR exchanger and an engine cooler, designed to cool an engine, on the same heat transfer fluid circulation loop.
  • the temperature of the EGR device is thus close to the temperature of the engine.
  • a thermostat device makes it possible to maintain the temperature of the heat transfer fluid leaving the engine at a predetermined value, for example 90° C.
  • a so-called mixed-loop cooling circuit can comprise an engine and a radiator in fluid communication so as to form a heat transfer fluid circulation loop, and an EGR exchanger arranged in fluid communication with the radiator so as to form an additional loop. circulation of the heat transfer fluid.
  • a thermostat can make it possible to close a valve on the loop serving the motor, so that when the temperature is below a threshold, for example 90°, the motor is not cooled by the heat transfer fluid.
  • a pump placed between the EGR exchanger and the radiator makes it possible to guarantee circulation of the coolant in the additional loop only, so as to cool the EGR exchanger.
  • GB2473437-A describes such a cooling circuit.
  • the cooling of the partial exhaust gas recirculation device it is possible to better control the temperature in this device and/or the temperature of the engine, or even possibly the temperature of other cooling consumer stations, such as for example a air heater managing the sending of hot gases into the passenger compartment.
  • a air heater managing the sending of hot gases into the passenger compartment.
  • the partial exhaust gas recirculation device can be an EGR device.
  • the cooler of the partial exhaust gas recirculation device is then called an EGR cooler.
  • This piloting of the third loop of a mixed loop circuit can thus be carried out independently of the (de)coupling between the loops.
  • the coupling device can comprise a thermostat arranged to open and close the second loop according to a measured temperature value or estimated, for example as a function of the temperature of the exhaust gases leaving the combustion chamber.
  • the second loop remains closed, so that the heat transfer fluid circulates only in the first and the third loop.
  • a threshold for example 90° C. or other
  • the at least one value received, from which the control signal of the third loop is produced can comprise a temperature value, for example a measured temperature value of the exhaust gases of the engine or heat transfer fluid leaving the engine.
  • provision may be made to reduce the cooling of the partial exhaust gas recirculation device when the temperature measured at the engine outlet is below a threshold, for example 85°, 105° C. or other.
  • the partial exhaust gas recirculation device may be less cooled than if the second pump were operating at the minimum of its capacities.
  • This can be advantageous as the radiator is designed and sized to cool the engine. The radiator can thus provide a relatively high cooling power. By limiting the cooling of the partial exhaust gas recirculation device, it is possible to prevent the temperature of the gases in this device from being too low.
  • control signal can be formulated in such a way as to avoid the boiling of the coolant. In fact, if the heat transfer fluid does not flow quickly enough, it risks evaporating.
  • control signal can be formulated in such a way as to limit the circulation of the heat transfer fluid in the EGR exchanger in the event of detection of the risk of engine overheating.
  • engine overheating it is meant here that the temperature of the coolant at the outlet of the engine exceeds a threshold value, for example a threshold value to which it is subject, for example 90° C., or else a triggering threshold value, for example example 110°C, or other.
  • the cooling circuit may prove to be insufficient to maintain the temperature around the desired threshold, for example 90°.
  • the circulation of heat transfer fluid in the third loop it is possible to limit the quantity of heat transfer fluid withdrawn by this third loop, and therefore allow a greater circulation of heat transfer fluid in the second loop (radiator), which can thus contribute to the engine cooling.
  • the operating point of the engine can be determined from, for example, the engine load and the engine speed.
  • the invention is not limited by the way in which a risk of engine overheating is detected.
  • the at least one value received and from which the control signal of the third loop is developed can be a temperature value, a Boolean parameter value indicative of the state of the EGR , a parameter value indicative of the engine speed, for example a number of revolutions per minutes, a parameter value indicative of the position of the accelerator pedal, and/or other.
  • control signal can be sent to the second pump in order to control this second pump.
  • the second pump can be an electric pump.
  • control signal can make it possible to control a supply voltage of the second pump.
  • the opening duty cycle (OCR) of the second pump goes from 100% to 50%
  • the flow in the radiator can be reduced by half
  • the invention is in no way limited by a control of the second pump.
  • a two- or three-way valve could be provided between the engine, the radiator and the EGR exchanger.
  • the heat transfer fluid from the engine is mainly redirected to the radiator rather than to the EGR exchanger, thus making it possible to cool the engine more than when a greater part of the fluid is taken from the third loop.
  • This two- or three-way valve can be controlled by a management device implementing the method described above.
  • the two-way or three-way valve can be a variable-flow valve.
  • the section of this valve can thus be controlled so as to reduce the flow in the third loop, for example during the start-up phase.
  • the cooling circuit can be a mixed loop circuit.
  • the receiving means may comprise, for example, an input pin, an input port and or other
  • the processing means may comprise a processor core or CPU (Central Processing Unit), a processor or the like.
  • CPU Central Processing Unit
  • the transmission means can for example comprise an output pin, an output port or the like.
  • the engine system comprising a partial exhaust gas recirculation device, the management device described above and the cooling circuit.
  • the engine of this vehicle may for example be a diesel engine, or not.
  • opening a loop it is meant that fluid communication is ensured so that the fluid can traverse the loop in the same direction, for example by opening a valve arranged on the loop.
  • closing a loop it is meant that part of the loop is isolated so as to prevent the circulation of fluid in the loop, for example by closing a valve placed on the loop.
  • a cooling circuit 1 comprises a heater 14, located in the passenger compartment of a motor vehicle not shown as a whole, and an engine 10, connected by conduits so as to form a first loop 21 for circulating heat transfer fluid.
  • Circuit 1 further comprises a radiator 11 arranged on a second heat transfer fluid circulation loop 22.
  • a first pump 12 makes it possible to circulate heat transfer fluid on this second loop so as to reduce the temperature of the engine.
  • a thermostat 13 placed at the output of motor 10 makes it possible to open and close this second loop 22 according to the temperature measured at the output of motor 10.
  • the unit heater 14 can be arranged on the first loop 21, so as to be able to benefit from the circulation of the heat transfer fluid.
  • a jar 15 can constitute a reserve of heat transfer liquid.
  • An EGR exchanger 16 can be placed on a third loop 23.
  • the conduits of this third loop 23 form a connection in parallel with respect to the second loop 22.
  • a second pump 17 can make it possible to circulate fluid between the EGR exchanger 16 and the engine radiator 11.
  • the curve 101 corresponds to temperature values of the coolant at the outlet of the engine 10 in the cooling system 1 of the figure 1 .
  • the curve 161 corresponds to temperature values at the outlet of the EGR exchanger 16 of the circuit of the figure 1 .
  • the curve 200 corresponds to the temperature values of the heat transfer fluid at the outlet of the EGR exchanger 16, when the pump 17 is uncontrolled and maintained at 100% of its capacity.
  • the engine temperature then increases throughout a starting phase until it reaches a threshold value, for example 90° C.
  • a threshold value for example 90° C.
  • the engine temperature increases linearly.
  • the thermostat 13 of the figure 1 makes it possible to close the second heat transfer fluid circulation loop 22 as long as this temperature value of the heat transfer liquid close to the motor 10 is less than 90°.
  • the radiator 11 thus only serves to cool the EGR exchanger 16.
  • the heat transfer fluid is relatively cold and the EGR exchanger 16 can be maintained at relatively low temperatures, for example around 45°C.
  • a management device for example a processor 18 on board the motor vehicle and further comprising the motor system, makes it possible to adapt the flow rate of the second electric pump 17, so as to optimize the operation of the various consumers and to limit the emission of polluting nitrogen oxides.
  • This processor 18 receives signals from various sensors not shown, for example a heat transfer fluid temperature sensor at the engine outlet, and generates a control signal for the second pump 17, so that the latter modulates the flow of coolant.
  • curve 161 may exhibit oscillations slightly greater than 50° C. during this start-up phase. Such temperature values are particularly advantageous in the sense that they make it possible to reconcile low emission of nitrogen oxides and limited risk of clogging.
  • the thermostat 13 opens the second loop 22, that is to say the pump 12 brings heat transfer fluid into the engine 10.
  • the temperature of the coolant is then controlled around 90°.
  • the loops 21, 22 and 23 being in fluid communication with each other, the temperature of the EGR exchanger quickly reaches 90°C.
  • Such a value which would correspond to relatively high levels of pollution and in the start-up phase, remains acceptable here because the EGR is generally inactive when the engine is sufficiently stressed.
  • the heat transfer fluid for example a glycol liquid
  • the heat transfer fluid circulates in the third loop in a clockwise direction in the diagram of the figure 1 .
  • heat transfer fluid arrives in the third loop 23 through what was then the outlet of the radiator 11, according to the arrow referenced 25 on the figure 1 .
  • the heat transfer fluid maintained at a temperature close to 55° C. in the third loop, is mixed with heat transfer fluid whose temperature is close to 90°, since coming from the engine 10, and, quickly, the temperature of the fluid in the EGR exchanger becomes close to that of the fluid in the engine 10.
  • the coolant fluid continues to circulate in the EGR exchanger in the same direction, that is to say on the figure 1 from right to left, but that, on the other hand, the circulation of the coolant in the radiator has been reversed.
  • the heat transfer fluid circulates from left to right on the figure 1 in the radiator 11.
  • the heat transfer fluid circulates from left to right in the radiator 11 of the figure 1 .
  • the radiator 11 is therefore designed to allow the circulation of the heat transfer fluid in both directions.
  • a management method can be implemented by the processor 18 of the figure 1 .
  • a temperature value of the coolant at the engine outlet T M is received, a value of a state_EGR parameter, indicative of the state of an EGR actuator, a value of a parameter of engine load pedal_pos and an engine rpm parameter value rpm_mot.
  • the state_EGR parameter can correspond to the position of the electric actuator linked to the management of the EGR.
  • the engine load parameter can for example be a mean effective pressure value (MEP) on the accelerator pedal.
  • MEP mean effective pressure value
  • the temperature value of the coolant T M is compared with a threshold value, for example 105° C. or 110° C.
  • step 203 a value of a control signal S is generated as a function of the parameter values pedal_pos and consist_mot. More precisely, a first two-dimensional map, called engine cooling map, can make it possible to read a control signal value as a function of the values of these two parameters. This first map is designed to, depending on the operating point of the engine, control the flow in the third loop so as to cool the EGR relatively little and to use the resources of the radiator to further cool the engine.
  • test 202 is negative, that is to say if the temperature is below the threshold value, then it is considered that the vehicle is in a starting or normal operating situation, with a limited risk of overheating.
  • the control value of the second electric pump is still developed according to the parameter values pedal_pos and regime_mot, but using a second two-dimensional map, different from the first map, during a step 204.
  • This second map is designed to control the flow so as to optimize the operation of the EGR, in particular so as to avoid clogging by amalgams.
  • the command signal value generated is transmitted in order to control the electric pump 17.
  • a loop can be set up with an output test 206, for example a test to check that the engine is still on, and a step of introducing a latency time 207, between the execution of two loops.
  • the invention is in no way limited by the way in which the electric pump is controlled.
  • the invention is not limited either to the use of mapping to produce the control signal, or even to particular mappings.
  • the engine cooling map used during step 203 can for example lead to a reduction of 30, 40 or 50% of the RCO for controlling the electric pump 17 when the engine is under relatively little demand, and to a reduction of 90% of this command when the values of the variables pedal_pos and regime_mot correspond to an over-solicitation of the engine.
  • the reliability map implemented in step 204 can also be designed to lower the flow rate in the third loop 23, for example to 40% of the maximum flow rate of the second pump, when the variables pedal_pos and regime_mot risk corresponding to a Beginning phase.
  • This sensor can provide measurement values that can make it possible to better discriminate start-up situations, and therefore to provide a management more suited to these start-up situations during which the third loop is isolated from the second loop.
  • the processor 18 can receive the values read by this sensor and be arranged to, when these values exceed a threshold, increase the flow rate in the third loop 23. It is in fact necessary to avoid the boiling of the heat transfer fluid in this third loop 23.
