Description
Die Erfindung betrifft einen Partikelfilter für einen Verbrennungsmotor.The invention relates to a particulate filter for an internal combustion engine.
Die
Der erfindungsgemäße Partikelfilter für einen Verbrennungsmotor umfasst eine aktive Struktur zur Abgasreinigung, wobei die aktive Struktur einen in Strömungsrichtung veränderlichen Querschnitt aufweist.The particle filter according to the invention for an internal combustion engine comprises an active structure for exhaust gas purification, wherein the active structure has a variable in the flow direction cross-section.
Der erfindungsgemäße Partikelfilter ermöglicht durch den veränderlichen Querschnitt der aktiven Struktur eine Optimierung des Gegendrucks, welcher durch den Partikelfilter hervorgerufen wird. Dies ermöglicht eine Erhöhung der Effizienz der Abgasreinigung des Verbrennungsmotors sowie eine Reduktion des Kraftstoffverbrauchs während des Betriebs des Verbrennungsmotors.Due to the variable cross section of the active structure, the particle filter according to the invention makes it possible to optimize the backpressure which is caused by the particle filter. This allows an increase in the efficiency of the exhaust gas purification of the internal combustion engine and a reduction in fuel consumption during operation of the internal combustion engine.
Zusätzlich ermöglicht der erfindungsgemäße Partikelfilter eine Optimierung des Bauraums, welcher durch den Partikelfilter beansprucht wird. Dadurch wird eine einfache Integration in bestehende Verbrennungsmotoren ermöglicht, auch wenn diese nur wenig Bauraum und/oder für herkömmliche Partikelfilter ungünstig ausgebildeten Bauraum bieten.In addition, the particle filter according to the invention makes it possible to optimize the installation space which is claimed by the particle filter. This allows easy integration into existing internal combustion engines, even if they offer only little space and / or unfavorable for conventional particulate filter space.
In einer bevorzugten Ausführungsform ist die aktive Struktur mittels eines generativen Verfahrens hergestellt.In a preferred embodiment, the active structure is produced by a generative process.
Durch die Verwendung eines generativen Verfahrens zur Herstellung der aktiven Struktur wird eine einfache und kostengünstige Herstellung des Partikelfilters ermöglicht. Insbesondere das Merkmal des veränderlichen Querschnitts der aktiven Struktur lässt sich durch herkömmliche Fertigungsverfahren von Partikelfiltern nicht und/oder nur unter großem Aufwand fertigen.The use of a generative process for the preparation of the active structure enables a simple and inexpensive production of the particulate filter. In particular, the feature of the variable cross section of the active structure can not be produced by conventional production processes of particle filters and / or only with great effort.
In einer weiteren bevorzugten Ausführungsform umfasst die aktive Struktur eine erste Teilstruktur zur Filterung von Partikeln und eine zweite Teilstruktur zur katalytischen Nachbehandlung von Abgas des Verbrennungsmotors.In a further preferred embodiment, the active structure comprises a first partial structure for filtering particles and a second partial structure for the catalytic aftertreatment of exhaust gas of the internal combustion engine.
Dadurch wird eine Kombination aus Partikelfilter und Katalysator innerhalb eines Bauteils ermöglicht. Dies ermöglicht eine zusätzliche Reduktion des benötigten Bauraums für die Abgasreinigung des Verbrennungsmotors.This allows a combination of particulate filter and catalyst within a component. This allows an additional reduction of the required space for the exhaust gas purification of the internal combustion engine.
Die erste Teilstruktur und die zweite Teilstruktur erzeugen dabei unterschiedliche Druckverluste für einen Abgasstrom. Je nach gewählter Anordnung der ersten Teilstruktur und der zweiten Teilstruktur, wird dadurch eine zusätzliche Optimierungen des Gegendrucks ermöglicht.The first substructure and the second substructure generate different pressure losses for an exhaust gas flow. Depending on the selected arrangement of the first substructure and the second substructure, thereby an additional optimizations of the back pressure is made possible.
Insbesondere eignet sich der erfindungsgemäße Partikelfilter aufgrund der Optimierung des Gegendrucks und des Bauraums für den Einsatz in Ottomotoren.In particular, the particle filter according to the invention is due to the optimization of the back pressure and the space for use in gasoline engines.
