Description

Die Erfindung betrifft eine Vorrichtung zur Steigerung der Durchlässigkeit des Einlaß- und Auslaßkanals von Hubkolbenbrennkraftmaschinen gemäß dem Oberbegriff des Anspruches 1. Die Erfindung läßt sich vorteilhaft bei Hubkolbenbrennkraftmaschinen anwenden, die große Über­ strömquerschnitte benötigen.The invention relates to a device for increasing the permeability of the inlet and outlet channels from Reciprocating internal combustion engines according to the preamble of Claim 1. The invention can be advantageous Reciprocating internal combustion engines use the big over flow cross sections need.

Der Gaswechsel des Verbrennungsraums von viertaktigen Hubkolbenbrennkraftmaschinen erfolgt bekannterweise über in den Verbrennungsraum ausmündenden Einlaß- und Auslaßkanälen, die durch zugehörige Tellerventile kon­ trollierbar sind. Die Oberflächengrößen der Verbren­ nungsräume setzen in weiter bekannter Weise eine Grenze für die Größen und die Durchlässigkeit der Einlaß- und Auslaßkanäle. Hierdurch ist die Höchstdrehzahl und die Höchstleistung dieser Viertaktbrennkraftmaschinen be­ schränkt. Bei bekannten Viertaktbrennkraftmaschinen (DE-PS 3 03 765, JP-PS 48-17 925, US-PS 42 73 083) ist bereits vorgeschlagen worden, an den Verbrennungsraum jeweils einen Kanal anzulegen, in dem ein Einlaß- und ein Auslaßkanal ausmündet und über die der Gaswechsel erfolgt. Diese Brennkraftmaschinen konnten sich jedoch wegen technischer Mängel nicht durchsetzen. Außerdem zeigten die Viertaktbrennkraftmaschinen nach der DE-PS 3 03 765 und JP-PS 48-17 925 Dichtprobleme und erforder­ ten außerdem eine zusätzliche komplizierte Ventilsteu­ erung. Die der US-PS 42 73 083 entnehmbare Lösung ist nur von prinzipieller Art und deswegen in technischer Hinsicht nicht brauchbar. The gas change of the combustion chamber from four-stroke Reciprocating internal combustion engines are known to take place via inlet and outlet into the combustion chamber Outlet channels, which are con are trollable. The surface sizes of the burns Space spaces set a limit in a well-known manner for the sizes and permeability of the inlet and Exhaust ducts. This is the maximum speed and the Top performance of these four-stroke engines limits. In known four-stroke internal combustion engines (DE-PS 3 03 765, JP-PS 48-17 925, US-PS 42 73 083) already proposed to the combustion chamber each create a channel in which an inlet and an outlet channel opens out and through which the gas exchange he follows. However, these internal combustion engines could not enforce due to technical defects. Furthermore showed the four-stroke internal combustion engines according to the DE-PS 3 03 765 and JP-PS 48-17 925 sealing problems and required an additional complicated valve control generation. The solution that can be found in US Pat. No. 4,273,083 only in principle and therefore in a technical way Not usable.  

Es ist Aufgabe der Erfindung einfache Maßnahmen zur sicheren Steigerung der Durchlässigkeit des Einlaß- und Auslaßkanals bei Hubkolbenbrennkraftmaschinen der vor­ genannten Art zu schaffen.It is an object of the invention to provide simple measures safe increase in the permeability of the inlet and Exhaust duct in reciprocating internal combustion engines before to create the kind mentioned.

Bevorzugt kann zwischen dem Teller­ ventil und der Nockensteuerwelle für dieses eine An­ druckfeder angeordnet sein, die vorteilhaft zur Ver­ meidung von Dichtproblemen beiträgt. Zweckmäßig ist die Ventilsitzfläche für den Einlaßkanal am freien Ende einer im Zylinderkopf angeordneten Gewindehülse ausge­ bildet.According to the invention it is provided that between the ends of the inlet facing the common channel duct and outlet duct a poppet valve is arranged, which has valve seats on both sides and with the Valve seat surfaces alternating on valve seat surfaces from Inlet channel or outlet channel can be created and its close the common channel with another valve or can be released. Preferably can be between the plate valve and the camshaft for this one compression spring can be arranged, which is advantageous for Ver avoidance of sealing problems. It is useful Valve seat surface for the inlet duct at the free end a threaded sleeve arranged in the cylinder head forms.

In Fortbildung der Vorrichtung ist vorgesehen, daß in den gemeinsamen Kanal ein Flügel angeordnet ist, der den Schaft des im gemeinsamen Kanal ausgebildeten Ven­ tils drehbeweglich umfaßt und sich auf eine zylinder­ kopffeste Gewindehülse abstützt. Mittels des Flügels ist die Möglichkeit gegeben, die Energie der Auspuff­ gase dahingehend zu verwerten, daß der erzielte Drall den jeweils neuen Gasfüllvorgang steigert. Schließlich ist noch vorgesehen, daß der Zylinderkopf mehr als einen sich am Verbrennungsraum anschließenden gemein­ samen Kanal aufweist, wobei an dem gemeinsamen Kanal jeweils zugehörige Einlaßkanäle und Auslaßkanäle anliegen können. Auf diese Weise sind eine Vielzahl von Varianten an konstruktiven Lösungen der Vorrichtung möglich. In a further development of the device it is provided that in a wing is arranged in the common channel the shaft of the Ven Tils rotatably embraced and on a cylinder Head-fixed threaded sleeve supports. By means of the wing there is an opportunity to exhaust the energy to utilize gases in such a way that the swirl achieved increases the new gas filling process. In the end it is also provided that the cylinder head more than one common to the combustion chamber has the same channel, being on the common channel associated inlet channels and outlet channels can concern. This way, a variety of Variants of constructive solutions of the device possible.  

Die Vorrichtung erbringt vorteilhaft eine Steigerung der Höchstdrehzahl und Höchstleistung um mehr als 30%, gegenüber einen kompressorlosen Motor, bei dem gleich­ zahlige Ventile dem Verbrennungsraum zugeordnet sind. Die mit der Vorrichtung ausgerüsteten Hubkolbenbrenn­ kraftmaschinen sind somit hinsichtlich Drehzahl und Leistung verbessert.The device advantageously provides an increase the maximum speed and maximum power by more than 30%, compared to a compressorless motor, in which the same numerous valves are assigned to the combustion chamber. The reciprocating piston burners equipped with the device engines are therefore in terms of speed and Performance improved.
