Der Erfindung liegt insbesondere die Aufgabe zugrunde, einen Verbrennungsvorgang in einer Brennkraftmaschine zu verbessern. Sie wird gemäß der Erfindung durch die Merkmale der unabhängigen Patentansprüche gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of improving a combustion process in an internal combustion engine. It is achieved according to the invention by the features of the independent claims. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Brennkraftmaschinenvorrichtung mit einer Ventiltriebvorrichtung, die eine Ventilhubumschalteinheit umfasst und die zumindest eine Nockenspur aufweist, die dazu vorgesehen ist, zumindest ein Auslassventil wenigstens zeitweise während einer Ansaugphase zu öffnen, mit einer Drosseleinrichtung, die zur Einstellung eines Ansaugquerschnitts vorgesehen ist, und mit einer Steuer- und/oder Regeleinheit zur Verstellung der Drosseleinrichtung.The invention is based on an internal combustion engine device having a valve drive device which comprises a valve lift switching unit and which has at least one cam track which is provided to open at least one outlet valve at least temporarily during an intake phase, with a throttle device which is provided for setting an intake cross section. and with a control and / or regulating unit for adjusting the throttle device.
Es wird vorgeschlagen, dass die Steuer- und/oder Regeleinheit dazu vorgesehen ist, zur Einstellung einer inneren Abgasrückführung die Drosseleinrichtung zu verstellen. Dadurch kann eine Abgasmenge, die durch die innere Abgasrückführung für einen nachfolgenden Verbrennungsvorgang einem Zylinder wieder zugeführt wird, zumindest in Teilbereichen stufenlos eingestellt werden, ohne dass eine vollvariable Ventiltriebvorrichtung für eine Auslassseite benötigt wird. insbesondere aufgrund der hohen Temperatur der rückgeführten Abgase kann dabei eine Verbesserung in Bezug auf einen Ausstoß von Kohlenmonoxid und Kohlenwasserstoffen erreicht werden. Zudem kann eine Abgastemperatur erhöht werden, wodurch insbesondere in einer Warmlaufphase Vorteile erreicht werden können. Durch eine erfindungsgemäße Ausgestaltung kann somit ein Verbrennungsvorgang einer Brennkraftmaschine optimiert werden, während Kosten und Aufwand für die Ventiltriebvorrichtung gering gehalten werden können. Unter einer „Ventilhubumschalteinheit” soll dabei insbesondere eine Einheit verstanden werden, die dazu vorgesehen ist, eine Ventilbetätigungscharakteristik für das zumindest eine Auslassventil in diskreten Schritten zu schalten, wie insbesondere eine Einheit, die dazu vorgesehen ist, das Auslassventil wirkungsmäßig in Kontakt mit einer von zumindest zwei Nockenspuren zu bringen. Unter einer „Nockenspur” soll dabei insbesondere ein Teil eines Auslassnockens verstanden werden, der zur direkten Betätigung des Auslassventils und/oder für einen Abgriff mittels eines Nockenfolgers zur Betätigung des Auslassventils vorgesehen ist. Vorzugsweise weist der zumindest eine Auslassnocken zumindest zwei Nockenspuren auf. Unter einer „Ansaugphase” soll insbesondere eine Phase während einem Arbeitszyklus verstanden werden, während der zumindest ein Einlassventil, das dem gleichen Zylinder zugeordnet ist wie das zumindest eine Auslassventil, geöffnet ist, um dem Zylinder ein zur Verbrennung geeignetes Luft-Abgas-Gemisch zuzuführen. Unter einem „Ansaugquerschnitt” soll insbesondere ein in der Ansaugphase wirksamer Querschnitt eines Ansaugtrakts verstanden werden. Unter einer inneren „Abgasrückführung” soll insbesondere eine Abgasrückführung verstanden werden, bei der Abgas aus dem Abgastrakt direkt wieder dem Zylinder zugeführt wird. Unter einer „Steuer- und/oder Regeleinheit” soll insbesondere eine Einheit mit zumindest einem Steuergerät verstanden werden. Unter einem „Steuergerät” soll insbesondere eine Einheit mit einer Prozessoreinheit und mit einer Speichereinheit sowie mit einem in der Speichereinheit gespeicherten Betriebsprogramm verstanden werden. Grundsätzlich kann die Steuer- und/oder Regeleinheit mehrere untereinander verbundene Steuergeräte aufweisen, die vorzugsweise dazu vorgesehen sind, über ein Bus-System, wie insbesondere ein CAN-Bus-System, miteinander zu kommunizieren. Unter „vorgesehen” soll insbesondere speziell programmiert, ausgestattet und/oder ausgelegt verstanden werden.It is proposed that the control and / or regulating unit is provided to adjust the throttle device for adjusting an internal exhaust gas recirculation. As a result, an amount of exhaust gas, which is returned to a cylinder by the internal exhaust gas recirculation for a subsequent combustion process, can be adjusted continuously, at least in some areas, without the need for a fully variable valve drive device for an exhaust side. In particular, due to the high temperature of the recirculated exhaust gases while an improvement in terms of emissions of carbon monoxide and hydrocarbons can be achieved. In addition, an exhaust gas temperature can be increased, which in particular in a warm-up phase benefits can be achieved. By means of an embodiment according to the invention, a combustion process of an internal combustion engine can thus be optimized, while costs and outlay for the valve drive device can be kept low. A "valve lift switching unit" is to be understood in particular as meaning a unit which is intended to switch a valve actuation characteristic for the at least one exhaust valve in discrete steps, in particular a unit which is intended to operatively bring the exhaust valve into contact with at least one of to bring two cam tracks. A "cam track" is to be understood in particular as meaning a part of an exhaust cam which is provided for the direct actuation of the exhaust valve and / or for a tap by means of a cam follower for actuating the exhaust valve. Preferably, the at least one exhaust cam has at least two cam tracks. An "intake phase" should be understood to mean, in particular, a phase during a work cycle, during which the at least one intake valve, which is assigned to the same cylinder as the at least one exhaust valve, is open, in order to supply the cylinder with an air / exhaust gas mixture suitable for combustion. An "intake cross section" is to be understood as meaning, in particular, a cross section of an intake tract which is effective in the intake phase. Under an internal "exhaust gas recirculation" is in particular an exhaust gas recirculation to be understood in the exhaust gas from the exhaust system is fed directly back to the cylinder. A "control and / or regulating unit" is to be understood in particular as a unit having at least one control unit. A "control unit" is to be understood in particular as meaning a unit having a processor unit and a memory unit as well as an operating program stored in the memory unit. In principle, the control and / or regulating unit can have a plurality of interconnected control units, which are preferably provided to communicate with one another via a bus system, in particular a CAN bus system. "Provided" is to be understood in particular specially programmed, equipped and / or designed.
Weiter wird vorgeschlagen, dass die Steuer- und/oder Regeleinheit dazu vorgesehen ist, eine Drosseleinrichtungsstellung in Abhängigkeit von einer Brennkraftmaschinentemperatur zu verstellen. Dadurch kann insbesondere in der Warmlaufphase die innere Abgasrückführung effektiv genutzt werden, um den Verbrennungsvorgang der Brennkraftmaschine zu verbessern. Beispielsweise kann dadurch verbrauchsneutral eine höhere Abgastemperatur erreicht werden, wodurch insbesondere Filter und/oder Katalysatoren, die in einem Abgastrakt angeordnet sind, vorteilhaft schnell auf Betriebstemperatur gebracht werden können, ohne dass dafür ein höherer Verbrauch in Kauf genommen werden muss. Zudem können durch einen Mischbetrieb der inneren Abgasrückführung mit einer externen Abgasrückführung, insbesondere einer Niederdruckabgasrückführung, ein Ausstoß von Kohlenmonoxiden und Kohlenwasserstoffen reduziert sowie ein vorteilhafter Lambda-Wert erreicht werden.It is further proposed that the control and / or regulating unit is provided to adjust a throttle device position as a function of an internal combustion engine temperature. As a result, in particular in the warm-up phase, the internal exhaust gas recirculation can be used effectively to improve the combustion process of the internal combustion engine. For example, a higher exhaust gas temperature can thereby be achieved without consumption, whereby in particular filters and / or catalysts, which are arranged in an exhaust tract, can advantageously be quickly brought to operating temperature, without having to accept a higher consumption. In addition, by a mixed operation of the internal exhaust gas recirculation with an external exhaust gas recirculation, in particular a low-pressure exhaust gas recirculation, an emission of carbon monoxides and hydrocarbons can be reduced and an advantageous lambda value can be achieved.
Zudem wird ein Verfahren zum Betrieb einer Brennkraftmaschinenvorrichtung mit einer Ventiltriebvorrichtung, die eine Ventilhubumschalteinheit umfasst und die eine Nockenspur aufweist, die zumindest ein Auslassventil wenigstens zeitweise während einer Ansaugphase öffnet, und mit einer Drosseleinrichtung, die zur Einstellung eines Ansaugquerschnitts vorgesehen ist, bei dem zur Veränderung einer inneren Abgasrückführung die Drosseleinrichtung verändert wird, vorgeschlagen, wodurch ein Verbrennungsvorgang in einer Brennkraftmaschine verbessert werden kann.In addition, a method of operating an internal combustion engine device with a valve train device, which is a valve lift switching unit and having a cam track, which opens at least one exhaust valve at least temporarily during a suction phase, and with a throttle device, which is provided for adjusting a Ansaugquerschnitts, in which is changed to change an internal exhaust gas recirculation, the throttle device, proposed, whereby a combustion process in one Internal combustion engine can be improved.
