- FIG. 1 schematically shows a combustion engine with the supply circuit according to the invention
- Figure 2 illustrates a combustion engine with a variant of the supply circuit of Figure 1.
- the internal combustion engine 10 in particular of diesel type, comprises at least one cylinder 12 inside which the combustion of a fuel mixture, an intake manifold 14 and an exhaust manifold 16.
- the intake manifold 14 is fed with at least one gaseous fluid (supercharged or non-supercharged air with or without recirculated exhaust gas) by a supply circuit 18 which comprises an air supercharging circuit 20 and a fuel circuit. exhaust gas recirculation 22.
- a supply circuit 18 which comprises an air supercharging circuit 20 and a fuel circuit. exhaust gas recirculation 22.
- the air supercharging circuit starts from an outside air inlet 24 and ends at the intake manifold 14.
- the outside air inlet 24 leads to a compression stage 26 for compressing this outside air.
- this compression stage is the compressor of a turbocharger 28 with a turbine 30 connected by a transmission shaft (not shown) to the compressor.
- the turbine is rotated by the exhaust gases resulting from the combustion of the fuel mixture in the cylinders and leaving the exhaust manifold 16. These gases then circulate in a pipe 32 which originates at this manifold and ends at the turbine . After passing through this turbine, these exhaust gases are discharged into the exhaust line through an outlet 34.
- the compressed air leaving the compressor 26 is directed by an air supercharging line 36 into the intake manifold 14
- a compressed air cooling radiator 38 more commonly referred to as a charge air cooler (RAS)
- RAS charge air cooler
- the exhaust gas recirculation circuit 22 comprises an exhaust gas recirculation duct 40 (more commonly referred to as exhaust duct).
- EGR which originates at a bypass 42 of the exhaust gas duct 32 and terminates either in the intake manifold or at a point 44 of the downstream air intake duct 36b, as illustrated in FIG. Figure 1.
- This EGR duct carries a recirculated exhaust gas cooler 46 and a valve 48, called EGR valve, for controlling the amount of exhaust gas flowing in the EGR duct. This valve is placed on the portion of the EGR duct located between the exhaust manifold 16 and the cooler 46.
- the supply circuit also comprises a connecting line 50 between the air supercharging circuit and the exhaust gas recirculation circuit. More precisely, this connecting line makes it possible to connect a point 52 of the upstream air intake duct 36 a with a junction point 54 of the part of the duct 40 located upstream of the cooler 46 and downstream of the EGR valve 48.
- This location of the connecting pipe thus makes it possible to operate the supercharging air radiator in parallel with the recirculated exhaust gas cooler to effect the cooling of the compressed air coming out of the compressor 26.
- the connecting pipe carries a flow control valve 56 for regulating the flow rate of the compressed air passing through the cooler 46.
- the portion of the upstream pipe 36a situated between the junction point 52 and the radiator charge air carries a flow control valve 58 to control the passage of compressed air into the radiator 38.
- the EGR valve 48 is in the closed position of the gas passage to the cooler and the flow control valves 56 and 58 are in the open position.
- the exhaust gases from the exhaust manifold 16 and flowing in the pipe 32 rotates the turbine 30 to be subsequently discharged through the outlet 34. This turbine rotates the compressor 26 so as to compress the pressure. outside air coming through the inlet 24.
- the compressed air leaving the compressor which is at a high temperature due to compression, circulates, for a part, in the upstream pipe 36a and, for the other part, in the connecting line 50 as well as in the portion of the duct 40 between the point 54 and the inlet of the cooler.
- one part of the compressed air is cooled by the radiator 38 and the other part is cooled by the exhaust gas cooler 46.
- the cooled compressed air leaving the radiator and that leaving the cooler is join at the junction point 44 to be directed into the intake manifold 14. From this manifold, the cooled compressed air is introduced into the cylinders 12 to be mixed with a fuel and achieve combustion of the fuel mixture.
- the cooler 46 Due to the additional cooling power (of the order of 5 to 10 KW) provided by the cooler 46 to lower the temperature of the compressed air, the possibility is offered to reduce the size of the radiator 38 while maintaining the performance of final exchange and the temperature of the compressed air in the collector which were previously obtained by conventional supply circuits. As a result, the span of the front of the vehicle can be reduced without penalizing the cooling of the charge air.
- this configuration is used to systematically clean the exhaust gas cooler.
- the compressed air passing through this cooler is at a high temperature, of the order of 150 to 180 ° C. This temperature is high enough to evaporate the soluble fractions of the particles deposited on the exchange walls of the cooler so that they disintegrate. Then, under the effect of the high speed of the compressed air circulating in the cooler, these disintegrated particles are detached from the exchange walls and are driven by the cooled compressed air to the engine inlet where they are introduced into the cylinder to be burned during the combustion of the fuel mixture.
- valves 56 and 58 can be controlled in such a way that the valve 58 either temporarily in the intermediate closed position, or in the fully closed position, and the valve 56 is in the fully open position. As a result, the amount of air passing through the cooler will be higher which can only accelerate the cleaning of this cooler.
- valve 56 In the case of low engine load operation where a recirculated exhaust gas inlet is required, the valve 56 is in the closed position of the connecting pipe 50, the valve 58 is in the open position of the pipe 36a. and the EGR valve 48 is actuated in opening according to the combustion conditions of the desired fuel mixture in the cylinders 12.
- This variant differs from Figure 1 in that the connecting line 50 allows the cooler 46 to operate in series with the radiator 38 to ensure cooling of the compressed air during operation at medium and high loads of the engine.
- the air supercharging circuit 20 of the supply circuit 18 of this variant therefore comprises an outside air inlet 24, an air compressor 26 forming part of a turbocharger 28, an air supercharging duct 36 and a charge air cooler 38 sharing the pipe 36 in an upstream pipe 36a and a downstream pipe 36b.
- the exhaust gas recirculation circuit 22 comprises an exhaust gas recirculation duct 40, which starts from the bypass 42 of the exhaust gas duct 32 and ends in the intake manifold 14, a cooler recirculated exhaust gas 46 and an EGR valve 48.
- the supply circuit of this variant also comprises a connection line 50 between the air supercharging circuit and the exhaust gas recirculation circuit.
- this connecting pipe makes it possible to connect the downstream air intake pipe 36b with the junction point 54 of the part of the duct 40 situated upstream of the cooler 46 and downstream of the EGR valve 48.
- the EGR valve 48 is in the closed position of the passage of the gases towards the cooler 46.
- the compressor 26 flows in the upstream pipe 36a and the radiator 38 to exit in the downstream pipe 36b with a temperature lower than that of the compressor outlet.
- the compressed air thus cooled is then directed by the connecting line 50 to the junction point 54 to pass through the cooler 46 and undergo another lowering temperature.
- the compressed air which has undergone a kind of "supercooling" by passing through the cooler 46, is directed towards the intake manifold 14 from which this compressed air is introduced into the cylinders 12 for be mixed with a fuel and burn the fuel mixture.
- the EGR valve 48 is actuated in opening to allow a portion of the exhaust gas to circulate to the intake manifold 14 after having passed through the cooler 46.
- the air cooled by passing through the radiator 38 is mixed at point 54 with the hot exhaust gases.
- the air / gas mixture is then cooled by the cooler 46 to reach the desired temperature in the intake manifold 14.
- both the radiator 38 and the cooler 46 are provided with a short-circuit respectively 60 and 62 comprising a winnowing means 64 and 66 and a control conduct. Contourement 68 and 70 of the exchanger 38, 46 to which it is applied.
- These short circuits are generally used during the cold start of the engine and therefore have no interdependence with the operation at mid-loads or heavy loads of the engine.
- the feed circuit described above is applied to a gasoline type internal combustion engine.
