Definitions
- the present invention relates to an internal combustion engine according to the preamble of claim 1.
- a system for recycling exhaust gas is known from EP 0 594 462 A1, which is intended for internal combustion engines with at least two intake valves.
- the exhaust gas is only introduced into one of the intake ducts.
- the feed takes place via a collector, which is relatively far upstream from the concerned Inlet valve is removed.
- Throttle valves can change the ratio of the intake air to the respective intake valves can be changed.
- An adjustment of the recirculated exhaust gas quantity and a stratification is also a way of the exhaust gas in the combustion chamber possible.
- this solution also suffers according to the relatively large line lengths and volumes of those described above Disadvantages.
- EP 0 558 072 A also discloses a direct-injection gasoline engine, which is an unusual intake port arrangement through the cylinder head having. Thanks to this special duct system, there are very short exhaust gas recirculation lines possible, each from the exhaust duct of the respective cylinder lead to the intake duct of the same cylinder. Through a common control valve the recirculated exhaust gas quantities of the individual cylinders are common controlled. Because with such an arrangement the exhaust gases immediately returned from the cylinder to the intake duct after a short distance this leads to considerable temperature problems in connection with Deposits and coking in the exhaust gas recirculation channels and to an undesirable heating of the cylinder head. The cylinder head itself is extremely complicated with such an arrangement of the intake channels difficult to manufacture. There is a particular disadvantage of this known solution however, in that due to gas dynamics in certain operating conditions strong fluctuations in the amount of exhaust gas recirculated occur.
- the object of the present invention is to provide a device in which the disadvantages described above can be avoided, and it in particular enables exhaust gas recirculation in a simple manner with a fast Response and more accurate metering of the recirculated exhaust gas create. In particular, gas dynamic effects should be exploited.
- An important aspect of the present invention is the most possible avoidance of dead volumes in the intake system, with the exhaust gases first Group of cylinders combined and an exhaust gas recirculation line Distribution device are supplied.
- This distribution device has an actuator on the metering of the recirculated exhaust gas controls for the individual cylinders together.
- the present invention enables the disadvantages described above to be avoided and at the same time exhibits a simple structure.
- Through the training according to the invention can Influences between the individual cylinders can be minimized. at For example, a four-cylinder in-line engine becomes two cylinders supply together with an ignition interval of 360 °, since this is an influence is low. With the usual firing order 1 - 3 - 4 -2 the cylinders become 1 and 4 and cylinders 2 and 3 supplied together.
- the distribution device is designed as a tube, which is essentially extends parallel to the longitudinal axis of the engine. It is possible that in the distribution device designed as a tube in the longitudinal direction Movable slide is provided, the opening controls that with the Exhaust gas recirculation are connected. However, it can also be a rotary valve be provided, the opening controls that with the exhaust gas recirculation stay in contact.
- the actuator has an auxiliary bore that a predetermined small opening cross-section for the exhaust gas recirculation defined.
- a predetermined small opening cross-section for the exhaust gas recirculation defined Preferably an exact one A small amount of exhaust gas can be measured.
- An additional exhaust gas recirculation valve can be provided upstream of the actuator his. In this way it is possible to regulate the exhaust gas recirculation quantity to be designed particularly fine.
- FIG. 1 is an intake manifold of an internal combustion engine according to the invention shown.
- the flange 1 is provided with screws 2 on the cylinder head attached to the internal combustion engine, not shown in FIG. 1 to become.
- Intake pipes 3 open into openings 4 for supplying the intake air.
- 3a is a partially cut intake duct.
- Parallel to the flange 1, a tube 5 is integrally formed with the flange 1, the represents the distribution facility.
- an actuator 6 in the Formed a rotary valve.
- the actuator 6 controls an exhaust gas recirculation opening 7 to adjust the amount of recirculated exhaust gas.
- about an opening 8 becomes exhaust gas from an exhaust gas recirculation line, not shown in FIG. 1 fed to the collector 9.
- the first exhaust gas recirculation line Exhaust gases are in via a first opening 11 in of the distribution device 5 is introduced into a first distribution space 12 which is formed between the actuator 6 and the tube 5. That of a second Exhaust gas recirculation line supplied exhaust gases through an opening 13 in a Room 14 out, which is also limited by the actuator 6 and the tube 5 is.
- a second Exhaust gas recirculation line supplied exhaust gases through an opening 13 in a Room 14 out which is also limited by the actuator 6 and the tube 5 is.
- the exhaust gas from cylinders 1 and 4 through the opening 11 into the channel 12, while the exhaust gas Cylinder 2 and 3 is guided through the opening 13 in the channel 14.
- a first one Group of openings 15 communicates with the first channel 12 while a second group of openings 16 in communication with the second channel 14 stands.
- the exhaust gas recirculation openings are in the position shown in FIG. 6 7 fully opened in the intake duct.
- FIG. 2 schematically shows the cylinder block 17 of an internal combustion engine shown, in which a piston 18 is movably arranged. From a cylinder head 19 lead exhaust ducts 20 away. Intake channels 21 are on their upstream Side connected to a collector 22, in front of which in turn a throttle valve 23 is arranged. An exhaust gas recirculation line 8 is with a Exhaust gas recirculation valve 24 is provided and leads to a distribution device 5, in 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 also of the distribution device 5 is supplied.
- the distribution device 5 is shown in detail in FIG. 3.
- the intake duct 21a is arranged.
- the distribution device 5 is integrally formed with the flange 1 of the intake manifold.
- Actuator 6 closes the suction opening 7 in the position shown in FIG. 3.
- FIG 5 shows an embodiment variant in which a flat slide 28 sets the opening cross-section for the exhaust gas recirculation.
