[0003] Die EP 0 840 000 A1 beschreibt eine Brennkraftmaschine mit einem Hochdruckabgasrückführsystem, wobei in der Abgasrückführleitung im Bereich der Entnahmestelle aus dem Abgasstrang ein Abgasrückführventil und im Bereich der Mündungsstelle in den Einlassstrang ein Rückschlagventil angeordnet ist.

[0005] Die Veröffentlichungen DE 10 2008 050 368 A1, WO 2009/151 080 A1, WO 2009/105 463 A1 und JP 2007/303 355 A offenbaren Brennkraftmaschinen mit einem Einlassstrang und einem Auslassstrang, einem Abgasturbolader, sowie einem Hochdruck-Abgasrückführsystem zwischen Auslassstrang und Einlassstrang, wobei im Abgasrückführstrang ein Abgasrückführkühler, ein Abgasrückführventil und ein Rückschlagventil angeordnet ist, welches stromaufwärts eines ersten Abgasrückführkühlers positioniert ist.

[0006] Weiters ist es aus den Druckschriften EP 1 835 155 A2, JP 2007-303 355 A, JP 2007-332 913 A, US 7,275,514 B2, US 7,360,523 B2, US 7,367,313 B2, US 7,370,0633 B2 und US 2009/0150052 A1 bekannt, eine negative Ventilüberschneidung für Einlass- und Auslassventile im Zusammenhang mit Abgasrückführung einzusetzen. Durch die negative Ventilüberschneidung kann die Druckdifferenz zwischen Abgasstrang und Einlassstrang positiv beeinflusst werden, um die Abgasrückführmengen zu erhöhen.Furthermore, it is known from the documents EP 1 835 155 A2, JP 2007-303 355 A, JP 2007-332 913 A, US Pat. No. 7,275,514 B2, US Pat. No. 7,360,523 B2, US Pat. No. 7,367,313 B2, US Pat. No. 7,370,02633 B2 and US Pat. 0150052 A1 known to use a negative valve overlap for intake and exhaust valves in connection with exhaust gas recirculation. Due to the negative valve overlap, the pressure difference between the exhaust tract and the intake manifold can be positively influenced in order to increase the exhaust gas recirculation quantities.
[0007] Aufgabe der Erfindung ist es, eine Verbrauchsabsenkung unter Einhaltung strengster Abgasrichtlinien zu realisieren.The object of the invention is to realize a reduction in consumption while adhering to the strictest emission guidelines.
[0008] Erfindungsgemäß wird dies dadurch erreicht, dass die Vorkühleinrichtung durch eine Kühlleitung innerhalb des Zylinderkopfes gebildet ist.This is inventively achieved in that the pre-cooler is formed by a cooling line within the cylinder head.
[0009] Die Vorkühleinrichtung kann auch durch Kühlrippen an einem zum Rückschlagventil führenden Abschnitt der Abgasrückführleitung oder durch eine Luftkühlung, erzielt durch gezieltes Anströmen eines zum Rückschlagventil führenden Abschnittes der Abgasrückführleitung und/oder durch Anströmen des Rückschlagventils, gebildet sein.The pre-cooling device can also be formed by cooling ribs on a leading to the check valve portion of the exhaust gas recirculation line or by air cooling, achieved by targeted flow against a leading to the check valve portion of the exhaust gas recirculation line and / or by flow of the check valve.
[0010] Besonders vorteilhaft ist es, wenn die Vorkühleinrichtung durch einen zweiten Abgasrückführkühler gebildet ist, wobei vorzugsweise das Abgasrückführventil stromabwärts des Rückschlagventils und/oder des ersten Abgasrückführkühlers angeordnet ist.It when the precooling device is formed by a second exhaust gas recirculation cooler, wherein preferably the exhaust gas recirculation valve downstream of the check valve and / or the first exhaust gas recirculation cooler is arranged is particularly advantageous.
[0011] Durch die Hochdruck-Abgasrückführung mit Rückschlagventil kann durch die Druck- 1 /6 österreichisches Patentamt AT511 604 B1 2013-01-15 pulsationen auch bei niedriger oder negativer Druckdifferenz zwischen Auslass- und Einlassstrang Abgas in den Einlassstrang rückgeführt werden. Um eine zylinderindividuelle Abgasrückführung zu ermöglichen, kann weiters vorgesehen sein, dass die Abgasrückführleitung sich in zumindest zwei Zweigleitungen aufspaltet, wobei die Zweigleitung zylinderindividuell jeweils in einen Einlasskanal unterschiedlicher Zylinder einmünden. Die Zuleitung zur Verteilerleiste erfolgt vorzugsweise mittig; die von der Verteil leiste abzweigenden Leistungen zu den Zylindern verlaufen vorzugsweise symmetrisch.Due to the high-pressure exhaust gas recirculation with a check valve, exhaust gas can be recirculated into the intake line even at low or negative pressure difference between outlet and inlet line through the pressure pulsation AT511 604 B1 2013-01-15 AT511 604 B1 2013-01-15. In order to enable a cylinder-specific exhaust gas recirculation, it can further be provided that the exhaust gas recirculation line splits into at least two branch lines, the branch line each opening into an inlet channel of different cylinders for each cylinder. The supply line to the distribution bar is preferably in the middle; the branching from the distribution services to the cylinders are preferably symmetrical.
[0012] Der Vorkühler vor dem Rückschlagventil verhindert eine Überhitzung des Rückschlagventils und ermöglicht es, die Temperaturgrenzen der Komponenten einzuhalten. Darüber hinaus werden Gasdynamische Effekte weniger gestört.The pre-cooler before the check valve prevents overheating of the check valve and makes it possible to comply with the temperature limits of the components. In addition, gas-dynamic effects are less disturbed.
[0013] In weiterer Ausführung der Erfindung ist vorgesehen, dass in zumindest einem Betriebsbereich, in welchem eine Abgasrückführung gewünscht ist, die Steuerzeit zumindest eines Einlassventils und/oder eines Auslassventils so verändert wird, dass eine negative Ventilüberschneidung auftritt, wobei vorzugsweise der Einlassschluss bei 1 mm Ventilhub, insbesondere in Betriebsphasen mit negativer Ventilüberschneidung, später als 590° Kurbelwinkel nach dem oberen Totpunkt der Zündung erfolgt. Dabei kann darüber hinaus vorgesehen sein, dass der Wechsel von positiver zu negativer Ventilüberschneidung durch Vorverstellen der Auslasssteuerzeiten erfolgt.In a further embodiment of the invention it is provided that in at least one operating range in which an exhaust gas recirculation is desired, the control time of at least one inlet valve and / or an outlet valve is changed so that a negative valve overlap occurs, preferably the inlet closing at 1 mm valve lift, especially in operating phases with negative valve overlap, later than 590 ° crank angle after the top dead center of the ignition takes place. It can also be provided that the change from positive to negative valve overlap occurs by Vorverstellen the Auslasssteuerzeiten.
[0014] Dabei beträgt die negative Ventilüberschneidung (bezogen auf 1 mm Ventilhub) 40° bis 120° Kurbelwinkel, vorzugsweise 60°bis 100°Kurbelwinkel.In this case, the negative valve overlap (based on 1 mm valve lift) 40 ° to 120 ° crank angle, preferably 60 ° to 100 ° crank angle.
[0015] Durch die negative Ventilüberschneidung wird gewährleistet, dass ausreichend hohe Abgasmengen vom Auslassstrang zum Einlassstrang rückgeführt werden können. Weiters werden Verluste durch zu spätes Auslassöffnen - insbesondere bei kurzer Öffnungsdauer der Auslassventile - vermieden.By the negative valve overlap ensures that sufficiently high amounts of exhaust gas can be recycled from the outlet to the inlet strand. Furthermore, losses due to late opening of the outlet are avoided, in particular if the outlet valves are opened for a short time.
[0016] Die Erfindung wird im Folgenden anhand der Fig. näher erläutert.The invention will be explained in more detail below with reference to FIG.
[0017] Es zeigen schematisch [0018] Fig. 1 eine erfindungsgemäße Brennkraftmaschine in einer ersten Ausführungsvariante, [0019] Fig. 2 eine erfindungsgemäße Brennkraftmaschine in einer zweiten Ausführungsvarian te, [0020] Fig. 3 die Steuerzeiten der Ein- und Auslassventile bei positiver Ventilüberschneidung und [0021] Fig. 4 die Steuerzeiten der Ein- und Auslassventile bei negativer Ventilüberschneidung.1 shows an internal combustion engine according to the invention in a first embodiment, [0019] FIG. 2 shows an internal combustion engine according to the invention in a second embodiment, [0020] FIG. 3 shows the timing of the intake and exhaust valves in positive Valve overlap and Fig. 4 shows the timing of the intake and exhaust valves at negative valve overlap.
