Abstract
Eine Ansaugvorrichtung hat einen Kanal, der unmittelbar oder mittelbar mit einem Zylinder einer Brennkraftmaschine kommuniziert, wenn die Ansaugvorrichtung an der Brennkraftmaschine angeordnet ist. Sie hat ferner eine Klappe (5), die auf einer Welle (7) gelagert ist und die in dem Kanal so angeordnet ist, dass sie in einer vorgegebenen Stellung eine Tumble-Strömung oder Swirl-Strömung in dem Zylinder erzeugt. Die Klappe hat mindestens eine Ausnehmung (11 bis 16), die sich von der Seite der Klappe, die der Hauptströmungsrichtung (9) in dem Kanal zugewandt ist, hin zu der Seite erstreckt, die der Hauptströmungsrichtung (9) in dem Kanal abgewandt ist. Dabei wird die Ausnehmung (11 bis 16) während des Betriebs der Brennkraftmaschine in Hauptströmungsrichtung (9) von einem Gasmassenstrom durchströmt, wodurch ein Druckausgleich erfolgt.An intake device has a channel that communicates directly or indirectly with a cylinder of an internal combustion engine when the intake device is arranged on the internal combustion engine. It also has a flap (5) which is mounted on a shaft (7) and which is arranged in the channel in such a way that it generates a tumble flow or swirl flow in the cylinder in a predetermined position. The flap has at least one recess (11 to 16) which extends from the side of the flap which faces the main flow direction (9) in the channel to the side which faces away from the main flow direction (9) in the channel. A gas mass flow flows through the recess (11 to 16) during operation of the internal combustion engine in the main flow direction (9), as a result of which pressure equalization takes place.
Description
Die Erfindung betrifft eine Ansaugvorrichtung, die insbesondere zum Einsatz in einer Brennkraftmaschine geeignet ist.The invention relates to a suction device, which are particularly suitable for use in an internal combustion engine is.
Aus der
Die Aufgabe der Erfindung ist es, eine Ansaugvorrichtung zu schaffen, durch die geringe Abgasemissionen gewährleistet sind.The object of the invention is to create an intake device through the low exhaust emissions guaranteed are.
Die Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The task is solved by the characteristics of the independent Claim. Advantageous embodiments of the invention are in the subclaims characterized.
Der Erfindung liegt die Erkenntnis zugrunde, dass sich in dem Bereich stromabwärts der Klappe Kraftstoffansammlungen bilden können und dass dies in überraschender Weise durch Ausnehmungen einfach verhindert werden kann.The invention is based on the knowledge underlying fuel accumulations in the area downstream of the flap can form and that this is surprising Way can be easily prevented by recesses.
