Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Drallerzeugung in einem Zylinder einer Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren hierzu gemäß Oberbegriff des Patentanspruchs 7.The The invention relates to a device for generating swirl in one Cylinder of an internal combustion engine according to the preamble of the claim 1 and a method for this according to the preamble of claim 7.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Drallerzeugung derart auszubilden, dass bei vereinfachter Herstellung der Vorrichtung ein optimaler Drall in einem Zylinder der Brennkraftmaschine erzeugbar ist.Of the Invention is based on the object, an apparatus and a method to form the swirl generation such that at a simplified production the device an optimal twist in a cylinder of the internal combustion engine can be generated.
Diese Aufgabe wird bei einer Vorrichtung zur Drallerzeugung in einem Zylinder einer Brennkraftmaschine durch die im Kennzeichen des Patentanspruchs 1 gegebenen Merkmale und bei einem Verfahren zur Drallerzeugung in einem Zylinder einer Brennkraftmaschine durch die im Kennzeichen des Patentanspruchs 7 gegebenen Merkmale gelöst.These Task is in a device for swirl generation in a cylinder an internal combustion engine by the in the characterizing part of patent claim 1 given characteristics and in a method for swirl generation in a cylinder of an internal combustion engine by the in the license plate of claim 7 given characteristics solved.
Drallerzeugung im Zylinder einer Brennkraftmaschine wird häufig durch Drallkanäle oder Tangentialkanäle im Gaswechselkanal realisiert. Diese bedingen aufwändige Kanalgeometrien und eine genaue Positionierung der Kanäle. Ein Vorteil der Erfindung besteht daher darin, dass diese zusätzlichen Kanäle im Gaswechselkanal entfallen können, da gleichwirkende Kanäle in den Ventilsitzring integriert sind.swirl generation in the cylinder of an internal combustion engine is often by swirl channels or tangential realized in the gas exchange channel. These require complex channel geometries and accurate positioning of the channels. An advantage of the invention is therefore that these additional channels in the gas exchange channel can be omitted, since same effect channels integrated in the valve seat ring.
Ein weiterer Vorteil der Erfindung besteht darin, dass die für das Öffnen des Gaswechselventiles aufzubringende Energie reduziert werden kann, indem der Ventilteller des Ventiles mit Öffnungen versehen ist. Beim Öffnen des Ventiles genügt dann ein geringfügiges Anheben des Ventiltellers im Zehntelbereich, damit eine Drehung des Ventiltellers möglich ist und zwar bis die Öffnungsquerschnitte der Öffnungen im Ventilteller und der Einlasskanäle mindestens teilweise aufeinanderliegen, so dass die Luft aus dem Gaswechselkanal in den Zylinder einströmen kann. Ein größerer Hub des Ventiles gegen die Federkräfte der Ventilfeder kann daher entfallen, wodurch sich die benötigte Öffnungsenergie reduziert, d.h. das Freigeben des Zylinders erfolgt nicht durch einen ausreichenden Hub des Ventiles sondern durch einen geringfügigen Hub und eine Rotation des Ventiles.One Another advantage of the invention is that for the opening of the Gas exchange valve applied energy can be reduced, in that the valve disk of the valve is provided with openings. When opening the Valves is enough then a minor one Raising the valve disk in tenths, allowing one turn the valve plate is possible and that until the opening cross-sections the openings in the valve plate and the inlet channels are at least partially superimposed, so that the air from the gas exchange channel can flow into the cylinder. One larger stroke of the valve against the spring forces of Valve spring can therefore be omitted, resulting in the required opening energy reduced, i. the release of the cylinder does not occur a sufficient stroke of the valve but by a slight stroke and a rotation of the valve.
