Definitions
- the present invention relates to an internal combustion engine with a device for the controlled recirculation of exhaust gas into intake ducts via an exhaust gas recirculation line, which is connected to the engine exhaust system.
- EP 0 594 462 A1 A system for recycling exhaust gas is known from EP 0 594 462 A1, which is suitable for Internal combustion engines with at least two intake valves is provided.
- the exhaust gas only introduced into one of the intake ducts.
- the supply takes place via a collector, which is located relatively far upstream from the inlet valve in question.
- throttle valves can change the ratio of the intake air to the respective intake valves will. In this way, an adjustment of the recirculated exhaust gas quantity and stratification of the exhaust gas in the combustion chamber possible.
- this solution also suffers according to the relatively large line lengths and volumes with the disadvantages described above.
- the object of the present invention is to provide a device in which the above Disadvantages described can be avoided, and which makes it possible in particular Exhaust gas recirculation in a simple way with a quick response and precise metering of the recirculated exhaust gas.
- each intake duct which is connected to a distribution device connected, which is supplied by an exhaust gas recirculation line, and that the distribution device has an actuator which is designed to the To control flow cross-sections for the exhaust gas through the exhaust gas recirculation openings together.
- What is essential to the present invention is the possible avoidance of dead volumes in the intake system, whereby the exhaust gases of a group of cylinders are first combined and are fed to a distribution device via an exhaust gas recirculation line.
- this distribution device has an actuator which is used for metering the returned Controls the amount of exhaust gas for the individual cylinders together.
- the present invention enables the disadvantages described above to be avoided and at the same time has one simple construction on.
- the Distribution device is designed as a tube that is substantially parallel to the longitudinal axis of the engine extends. It is possible that in the distribution device designed as a tube a longitudinally movable slide is provided, the openings controls that are connected to the exhaust gas recirculation. However, it can also be a Rotary vane can be provided, the opening controls that with the exhaust gas recirculation in Connect.
- the actuator has an auxiliary bore having a predetermined small Opening cross section defined for exhaust gas recirculation. In this way it is achieved that in a central position of the actuator even if there are manufacturing tolerances or other inaccuracies a precise metering of a small amount of exhaust gas is possible.
- An additional exhaust gas recirculation valve can preferably be located upstream of the actuator be provided. In this way it is possible to regulate the exhaust gas recirculation quantity to be designed particularly fine.
- FIG. 1 shows an intake manifold of an internal combustion engine according to the invention.
- the flange 1 is provided with screws 2 on the cylinder head in FIG. 1 Internal combustion engine not shown to be attached.
- Intake pipes 3 open into Openings 4 for supplying the intake air.
- 3a is a partially cut intake duct designated.
- Parallel to the flange 1, a tube 5 is integral with the flange 1 trained, which represents the distribution device.
- an actuator 6 in the Formed a rotary valve.
- the actuator 6 controls an exhaust gas recirculation opening 7 to set the amount of recirculated exhaust gas.
- Through an opening 8 is exhaust gas from an exhaust gas recirculation line, not shown in FIG. 1, to the collector 9.
- FIG. 6 Another exhaust gas recirculation line from another cylinder group is on the flange 10 to fix.
- This distribution device is shown in more detail in FIG. 6. From Exhaust gases from a first exhaust gas recirculation line are discharged through a first opening 11 in the distribution device 5 inserted into a first distribution space 12, which between the actuator 6 and the tube 5 is formed. From a second exhaust gas recirculation line Exhaust gases are fed through an opening 13 into a space 14, which also is limited by the actuator 6 and the tube 5. For example, with a four-cylinder engine the exhaust gas from cylinders 1 and 4 are led through opening 11 into channel 12, while the exhaust gas of the cylinders and 3 is led through the opening 13 into the channel 14. A first group of openings 15 communicates with the first channel 12 while a second group of openings 16 communicates with the second channel 14. In the in the position shown in FIG. 6, the exhaust gas recirculation openings 7 are in the intake duct completely turned on.
- the cylinder block 17 of an internal combustion engine is shown schematically in the a piston 18 is movably arranged.
- Exhaust ducts 20 lead from a cylinder head 19 path.
- Intake channels 21 are on their upstream side with a collector 22 connected, in front of which in turn a throttle valve 23 is arranged.
- An exhaust gas recirculation line 8 is provided with an exhaust gas recirculation valve 24 and leads to a distribution device 5, in which a rotary valve 6 is arranged as an actuator.
- the rotary valve 6 controls the exhaust gas recirculation opening 7. It is indicated schematically that a crankcase ventilation or a tank vent 25 is also supplied to the distribution device 5 becomes.
- the distribution device 5 is shown in detail in FIG. 3.
- the distribution device 5 is integral with the flange 1 of the intake manifold.
- the actuator 6 closes in that shown in Fig. 3 Position the suction opening 7.
- FIG 5 shows an embodiment variant in which a flat slide 28 has the opening cross section for exhaust gas recirculation.
- the present invention With the present invention, large amounts of exhaust gas recirculation are greater than 25% possible, achieving a particularly favorable dynamic behavior of the internal combustion engine becomes. Furthermore, the present invention provides particularly good driving behavior reached.
- the structure according to the invention is simple and easy to manufacture.
