Definitions
- the invention relates to an exhaust gas recirculation system for an internal combustion engine with an inlet and outlet line system, which has a charge air line, to which exhaust gas is supplied via an exhaust gas recirculation line and an exhaust gas recirculation valve.
- a device of the type mentioned at the outset which provides the exhaust gas recirculation valve with an integrated exhaust gas supply device in front of the charge air distributor.
- the recirculated exhaust gases are cooled in the exhaust gas recirculation line at partial load.
- the exhaust gases form a so-called paint in a certain temperature range, which prevents the exhaust gas recirculation valve from working properly.
- the object of the invention is to design and arrange the exhaust gas recirculation valve and the exhaust gas supply device in such a way that maintenance-free exhaust gas recirculation is possible or the formation of paint is prevented.
- the object is achieved according to the invention in that the exhaust gas recirculation valve arranged in an external part of the exhaust gas recirculation line is assigned a separate exhaust gas supply device. This ensures that, on the one hand, the exhaust gas recirculation valve does not come into contact with the fresh air flow and thus also not with the oil of the crankcase ventilation carried in the fresh air flow, and on the other hand cooling of the exhaust gas recirculation valve by the fresh air flow is prevented.
- the exhaust gas recirculation valve can be provided anywhere between the cylinder head and the exhaust gas supply device. The separation of the exhaust gas recirculation valve from the crankcase ventilation oil carried in the fresh air also prevents clogging by a soot-oil mixture.
- the exhaust gas recirculation valve in Seen flow direction, after a cylinder head and before Exhaust gas supply device is arranged as a mixing device is trained.
- the temperature level of the exhaust gases is in this area is still high enough to prevent the Avoid valve or valve seat.
- the actuators of the valve are effectively reduced by the adhesive forces of the Paint layer in the valve seat.
- the critical temperature range of the Paint will definitely form after the engine starts run through so that the critical in normal normal operation Temperature is exceeded.
- an additional possibility is the device according to the invention that the exhaust gas supply device, seen in the direction of flow, in front of a charge air distributor and is arranged after the exhaust gas recirculation valve and that the exhaust gas supply device two inlet openings for fresh air and Exhaust gas and two outlet openings for fresh air and exhaust gas has, the outlet opening for exhaust gas centrally in the outlet opening for fresh air is arranged.
- the Charge air distributor can change the temperature level during part-load operation the exhaust gases sink to the critical area. The paint formation would thus be favored, the lapping of the flow channels at this point no impact on the Has functionality of the exhaust gas supply device.
- the exhaust gas supply device occurs with the fresh air flow and thus also with the crankcase ventilation oil carried by the fresh air flow in contact due to the centric inflow of the exhaust gas in the fresh air flow, however, this is via the Fresh air flow entrained oil of the crankcase ventilation and the proportion of soot is mixed evenly in the wake of the outlet opening or distributed and thus carried by the fresh air flow. Also that carried on the wall of the fresh air line Oil leads in connection with the centrally flowing The soot content does not clog the line cross-sections. The paint formation and clogging of the exhaust gas supply device or the guide channels is thus prevented.
- the exhaust gas recirculation valve has an actuator and that the actuator in the exhaust gas recirculation valve is carried out pneumatically or electro-mechanically.
- the electro-mechanical steeper sits directly on the exhaust gas recirculation valve and is controlled via the motor cable set.
- the pneumatic Control and the electro-pneumatic converter fall away with this training.
- the exhaust gas recirculation valve with a cooling device of the cylinder head is in operative connection. This can be used if necessary or cooled the exhaust gas recirculation valve in full load operation and thus the actuator of the exhaust gas recirculation valve from overheating to be protected.
- the exhaust gas recirculation line has part integrated in the cylinder head and an external part.
- the integrated exhaust gas recirculation line is designed as an additional channel in the cylinder head. about the duct wall carries the exhaust gas heat to the cylinder head or on its cooling water circuit.
- an additional possibility is the Device according to the invention that the exhaust gas recirculation valve and the exhaust gas supply device via the external exhaust gas recirculation line are in operative connection.
- the external exhaust gas recirculation line is designed as a combination pipe and has an exhaust duct and a cooling water channel.
- the cooling water channel protrudes the exhaust gas recirculation valve with the cooling water circuit of the cylinder head in operative connection. The distance of the exhaust gas recirculation valve to the cylinder head and the associated exhaust gas temperature can thus be varied.
- the inlet opening for fresh air to the charge air line, the inlet opening for exhaust gas to the external exhaust gas recirculation line, the outlet opening for fresh air to the charge air distributor and the outlet openings for exhaust gas as well are connected to the charge air distributor.
- the exhaust gas flow is thus mixed into the fresh air flow.
- the exhaust gas begins to flow into the fresh air flow Mixing process of the two gas flows. This does not result in any significant ones Soot-oil deposits in the area of the exhaust gas supply device and clogging is prevented.
- the exhaust gas recirculation valve seen in the direction of flow is provided directly in front of the exhaust gas supply device, wherein the exhaust gas recirculation valve and the exhaust gas supply device Functionally arranged in a housing and via the inlet opening for exhaust gas in flow connection.
- the functional Separation of exhaust gas recirculation valve and exhaust gas supply device ensures that the exhaust gas recirculation valve is not from the Fresh air flows around and is therefore not cooled.

- the compressed fresh air is used as charge air in the charge air cooler 6 cooled and further via the charge air line 8 and Exhaust gas supply device 10 is supplied to the charge air distributor 7.
- the compressed and cooled Fresh air mixed with exhaust gas In the exhaust gas supply device 10, the compressed and cooled Fresh air mixed with exhaust gas.
- the exhaust gas is here via part 4 of the exhaust gas recirculation line integrated in a cylinder head 3 fed to the exhaust gas recirculation valve 9. about the external part 4 'of the exhaust gas recirculation line is regulated in this way Exhaust gas flow passed to the exhaust gas supply device 10.
- the exhaust gas recirculation valve 9 regulates via a steep 11 (FIG. 4) the fresh air supplied in the exhaust gas supply device 10 Exhaust gas flow, so that in the charge air distributor 7 a homogeneous Fresh air and exhaust gas mixture is created. This homogeneous fresh air and exhaust gas mixture is shown via the inlet channels 17 in Fig. 2 Cylinders 18 fed.
- the integrated part 4 of the exhaust gas recirculation line runs inside of the cylinder head 3 from the exhaust side to the intake side and connects to the exhaust gas recirculation valve 9. Here there the exhaust gas flow already transfers heat to the cylinder head.
- the external part 4 'of the exhaust gas recirculation line has two channels 27, 28, the channel 28 with the cooling water circuit of the cylinder head and the channel 27 as the actual one Exhaust gas recirculation line is used.
