Daraus resultieren unerwünscht hohe Kosten für die Brennkraftmaschine. The known internal combustion engines have a relatively high complexity, in particular with regard to their production, which is due in particular to a large number of flange surfaces to be sealed.

Patentanspruchs 1 sowie durch ein Verfahren zum Herstellen einer solchen Patent claim 1 and by a method for producing such
Brennkraftmaschine mit den Merkmalen des Patentanspruchs 10 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Der erste Aspekt der Erfindung betrifft eine Brennkraftmaschine mit mehreren Zylindern mit mindestens einem Zylinderkopf, wobei Einlässe des Zylinderkopfes an einer Internal combustion engine solved with the features of claim 10. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims. The first aspect of the invention relates to an internal combustion engine having a plurality of cylinders with at least one cylinder head, wherein inlets of the cylinder head to a
Einlassflanschfläche und Auslasskanäle an einer gegenüberliegenden Inlet flange surface and outlet channels on an opposite
Auslassflanschfläche münden und wobei oberhalb eines Raumes im Zylinderkopf, der die Ein- und Auslasskanäle und einen Kühlmittelraum aufnimmt, ein Ölraum für eine Auslassflanschfläche open and wherein above a space in the cylinder head, which receives the inlet and outlet ducts and a coolant space, an oil chamber for a
Betätigungsvorrichtung für Gaswechselventile vorgesehen ist. Actuating device is provided for gas exchange valves.

gegeneinander geneigt angeordnet, so dass eine gedachte Schnittgerade der beiden Flanschflächen in Hochrichtung der Brennkraftmaschine oberhalb des Zylinderkopfes liegt und der Zylinderkopf einen zumindest im Wesentlichen dreiecksförmigen Querschnitt aufweist. arranged inclined to each other, so that an imaginary line of intersection of the two flange faces in the vertical direction of the engine above the cylinder head and the cylinder head has an at least substantially triangular cross-section.
Dadurch kann im Vergleich zu herkömmlichen Brennkraftmaschinen eine abzudichtende Flanschfläche zwischen dem Zylinderkopf und einer Zylinderkopfhaube sowie die As a result, in comparison to conventional internal combustion engines to be sealed flange between the cylinder head and a cylinder head cover and the
Zylinderkopfhaube selbst entfallen. Die erfindungsgemäße Brennkraftmaschine weist damit eine geringe Komplexität auf, was ihren Fertigungsaufwand und damit ihre Kosten gering hält. Ferner weist sie nur eine geringe Teileanzahl auf, was den geringen Kosten ebenso zuträglich ist. Da bei der erfindungsgemäßen Brennkraftmaschine im Vergleich zu herkömmlichen Brennkraftmaschinen die abzudichtende Flanschfläche zwischen dem Zylinderkopf und der Zylinderkopfhaube entfallen kann bzw. deren Funktion in die Cylinder head cover itself omitted. The internal combustion engine according to the invention thus has a low complexity, which keeps their production costs and thus their costs low. Furthermore, it has only a small number of parts, which is also beneficial to the low cost. Since in the internal combustion engine according to the invention compared to conventional internal combustion engines, the sealed flange surface between the cylinder head and the cylinder head cover can be omitted or their function in the
Einlassflanschfläche und die Auslassflanschfläche integriert ist, ist auch der Aufwand zum Abdichten der erfindungsgemäßen Brennkraftmaschine sowie ihr Montageaufwand als gering zu beziffern, was die Gesamtkosten um ein weiteres in einem geringen Rahmen hält. Darüber hinaus ist die erfindungsgemäße Brennkraftmaschine besonders Inlet flange and the Auslassflanschfläche is integrated, is also the cost of sealing the internal combustion engine according to the invention and their assembly costs to be low, which keeps the total cost of another in a small frame. In addition, the internal combustion engine according to the invention is special
prozesssicher und damit kostengünstig herstellbar. reliable and thus inexpensive to produce.
Ein weiterer Vorteil der erfindungsgemäßen Brennkraftmaschine ist, dass sie Another advantage of the internal combustion engine according to the invention is that they
insbesondere aufgrund der gegeneinander geneigten Anordnung der Flanschflächen einen nur sehr geringen Bauraumbedarf aufweist. So können Package-Probleme, insbesondere in einem platzkritischen Bereich wie einem Motorraum eines Kraftwagens, insbesondere eines Personenkraftwagens, gelöst oder vermieden werden. Especially due to the mutually inclined arrangement of the flange has only a very small space requirement. Thus, package problems, in particular in a space-critical area such as an engine compartment of a motor vehicle, in particular a passenger car, can be solved or avoided.
In einer vorteilhaften Ausführungsform der Erfindung weist der Ölraum des In an advantageous embodiment of the invention, the oil space of the
Zylinderkopfes jeweils mindestens eine Öffnung zu den beiden Flanschflächen auf. Cylinder head in each case at least one opening to the two flange surfaces.
Dadurch ist der ölraum besonders einfach zugänglich, was den Montageaufwand und den Wartungsaufwand der erfindungsgemäßen Brennkraftmaschine gering hält. Ferner ist dadurch eine besonders unaufwendige und kostengünstige Herstellung des As a result, the oil chamber is particularly easy to access, which keeps the assembly costs and the maintenance of the internal combustion engine according to the invention low. Further is characterized a particularly inexpensive and cost-effective production of the
Zylinderkopfes und damit mit der gesamten Brennkraftmaschine ermöglicht. Cylinder head and thus allows the entire internal combustion engine.
Ist oberhalb des Ölraums ein Längssteg vorgesehen, der Durchlässe für Zündkerzen und/oder Einspritzdüsen, Injektoren oder dergleichen aufweist, so birgt dies den Vorteil, dass dadurch die Zündkerzen und/oder die Einspritzdüsen besonders einfach mit dem Zylinderkopf zu verbinden bzw. an diesem anzuordnen sind. If a longitudinal web is provided above the oil space, which has passages for spark plugs and / or injection nozzles, injectors or the like, this has the advantage that the spark plugs and / or the injection nozzles are particularly easy to connect to the cylinder head or to be arranged thereon ,
Eine besonders zeit- und kostengünstige Montage der Brennkraftmaschine ist ermöglicht, wenn Zylinderkopfschrauben zur Verschraubung des Zylinderkopfes mit einem A particularly time- and cost-effective installation of the internal combustion engine is made possible when cylinder head bolts for screwing the cylinder head with a
Motorgehäuse der Brennkraftmaschine durch die Öffnungen des Ölraums in den Motor housing of the internal combustion engine through the openings of the oil chamber in the
Flanschflächen direkt zugänglich sind. So kann der Zylinderkopf beispielsweise mit einem einfachen Standardwerkzeug und für eine montierende Person ergonomisch günstig zugänglich mit dem Motorgehäuse verschraubt werden. Dadurch sind geringe Taktzeiten zur Herstellung und Montage der Brennkraftmaschine ermöglicht, was die Kosten gering hält. Flange surfaces are directly accessible. Thus, the cylinder head, for example, with a simple standard tool and for a person to be mounted ergonomically cheap to be screwed to the motor housing. As a result, low cycle times for the manufacture and assembly of the internal combustion engine are possible, which keeps costs low.
In einer weiteren vorteilhaften Ausführungsform der Erfindung ist die Einlassflanschfläche des Zylinderkopfes zumindest bereichsweise durch ein Ansaugmodul abgedeckt, das sowohl die Einlasskanäle als auch die Öffnung zum Ölraum dicht, insbesondere fluiddicht und insbesondere öldicht, abdeckt. Mit anderen Worten bedeutet dies, dass im Vergleich zu herkömmlichen Brennkraftmaschinen die abdichtende Funktion der Zylinderkopfhaube zumindest anteilig in das Ansaugmodul integriert ist, welches auch die Einlasskanäle abdeckt. Das Ansaugmodul weist somit eine hohe Funktionsintegration auf, was die Teileanzahl und die Kosten der Brennkraftmaschine gering hält. In a further advantageous embodiment of the invention, the inlet flange of the cylinder head is at least partially covered by an intake module that covers both the inlet channels and the opening to the oil chamber tight, in particular fluid-tight and oil-tight. In other words, this means that in comparison to conventional internal combustion engines, the sealing function of the cylinder head cover is at least partially integrated into the intake module, which also covers the intake ports. The intake module thus has a high degree of functional integration, which keeps the number of parts and the cost of the internal combustion engine low.
Das Ansaugmodul ist beispielsweise aus Kunststoff ausgebildet, so dass dieses und damit die Brennkraftmaschine ein besonders geringes Gewicht aufweisen. Ferner resultieren daraus besonders geringe Materialkosten, was den geringen Kosten für die Brennkraftmaschine zuträglich ist. The intake module is formed for example of plastic, so that this and thus the internal combustion engine have a particularly low weight. Furthermore, this results in particularly low material costs, which is beneficial to the low cost of the internal combustion engine.
Des Weiteren ist es sehr vorteilhaft, wenn die Auslassflanschfläche des Zylinderkopfes durch ein Abgaskrümmermodul abgedeckt ist, was sowohl die Auslasskanäle als auch die Öffnungen zum Ölraum dicht, insbesondere fluiddicht und insbesondere öldicht, abdeckt. Im Vergleich zu herkömmlichen Brennkraftmaschinen ist dadurch die abdichtende Funktion der Zylinderkopfhaube zumindest anteilig in das Abgaskrümmermodul integriert, so dass das Abgaskrümmermodul einen besonders hohen Funktionserfüllungsumfang aufweist. Dies führt zu einer geringen Teileanzahl, zu geringen Kosten sowie zu einem geringen Gewicht der Brennkraftmaschine. Furthermore, it is very advantageous if the Auslassflanschfläche the cylinder head is covered by an exhaust manifold module, which covers both the exhaust ports and the openings to the oil chamber tight, in particular fluid-tight and in particular oil-tight. Compared to conventional internal combustion engines thereby the sealing function of the cylinder head cover is at least partially integrated into the exhaust manifold module, so that the exhaust manifold module a particularly high functional performance having. This leads to a low number of parts, at low cost and to a low weight of the internal combustion engine.
Das Abgaskrümmermodul ist beispielsweise als dünnwandiges Umformteil aus einem Metall ausgebildet, so dass auch der Herstellungsaufwand und die Herstellungskosten des Abgaskrümmermoduls gering sind, dieses aber gleichzeitig hohe Belastungen, insbesondere hohe Temperaturbelastungen, während des Betriebs der The exhaust manifold module is formed, for example, as a thin-walled forming part of a metal, so that the manufacturing cost and manufacturing costs of the exhaust manifold module are low, but this high loads, especially high temperature loads, during operation of the
Brennkraftmaschine schadfrei über eine lange Lebensdauer hinweg ertragen kann. Internal combustion engine can endure damage over a long life span.
Die Betätigungsvorrichtung für die Gaswechselventile umfasst beispielsweise eine den Auslasskanälen zugeordnete Nockenwelle und/oder eine den Einlasskanälen The actuator for the gas exchange valves comprises, for example, a camshaft associated with the exhaust ducts and / or one of the intake ducts
zugeordnete Nockenwelle. Zur Lagerung der Nockenwellen an dem Zylinderkopf ist beispielsweise eine Lagergasse vorgesehen, welche teilweise durch den Zylinderkopf gebildet ist. Zur Halterung der Nockenwellen an dem Zylinderkopf ist die Lagergasse teilweise auch durch Lagerdeckel gebildet, welche an dem Zylinderkopf zu befestigen, beispielsweise zu verschrauben, sind. Dabei kann vorteilhafterweise vorgesehen sein, dass die Lagerdeckel in das Ansaugmodul und/oder das Abgaskrümmermodul integriert sind. Wird dann eines dieser Module mit den integrierten Lagerdeckeln an dem assigned camshaft. For storage of the camshaft on the cylinder head, for example, a storage lane is provided, which is partially formed by the cylinder head. For supporting the camshaft on the cylinder head, the storage lane is partially formed by bearing caps, which attach to the cylinder head, for example, to screw, are. It can advantageously be provided that the bearing caps are integrated into the intake module and / or the exhaust manifold module.
