Description
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zur Nutzung der Abgaswärme eines Verbrennungsmotors.The present invention relates to an apparatus and a method for utilizing the exhaust heat of an internal combustion engine.
Verbrennungsmotoren werden heutzutage mit Hilfe von Abgasturboladern aufgeladen. Dadurch gewinnt man durch eine im Abgasstrang angeordnete Turbine Abgasenergie des Verbrennungsmotors zurück. Die vom Abgas angetriebene Turbine wird zum Antrieb eines Turboverdichters verwendet, der den Verbrennungsmotor mit unter Druck stehendem Frischgas versorgt. Trotz der teilweisen Rückgewinnung der Abgasenergie mit Hilfe der im Abgasstrang angeordneten Turbine herrschen am Turbinenaustritt immer noch Abgastemperaturen, die hoch genug sind, um sie zu einer Wandlung in eine nutzbare Energieform zu verwenden.Internal combustion engines are nowadays charged by means of exhaust gas turbochargers. As a result, exhaust gas energy of the internal combustion engine is recovered by a turbine arranged in the exhaust system. The driven by the exhaust turbine is used to drive a turbocompressor, which supplies the internal combustion engine with pressurized fresh gas. Despite the partial recovery of the exhaust gas energy with the aid of the turbine arranged in the exhaust system, exhaust gas temperatures which are high enough to be converted into a usable form of energy still prevail at the turbine outlet.

Aufgabe der vorliegenden Erfindung ist es, die Nachteile aus dem Stand der Technik zu überwinden und eine einfache, kostengünstige Vorrichtung und ein dazugehöriges Verfahren zur effizienten Nutzung der Abgaswärme eines Verbrennungsmotors bereitzustellen.The object of the present invention is to overcome the disadvantages of the prior art and to provide a simple, inexpensive device and associated method for the efficient use of the exhaust heat of an internal combustion engine.
Erfindungsgemäß gelingt die Lösung dieser Aufgabe vorrichtungsseitig mit den im ersten Patentanspruch angegebenen Merkmalen und verfahrensseitig mit den Merkmalen des neunten Patentanspruchs.According to the invention, the solution of this object succeeds on the device side with the features specified in the first claim and on the procedural side with the features of the ninth patent claim.
Bevorzugte weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Preferred further embodiments of the invention are specified in the subclaims.
Einzelheiten und Vorteile der Erfindung sind der nachfolgenden Beschreibung zu entnehmen, mit der die Erfindung unter Bezugnahme auf die beigefügten Zeichnungen vorgestellt wird. Es zeigt:Details and advantages of the invention will become apparent from the following description, with which the invention with reference to the accompanying drawings is presented. It shows:
Beim Öffnen der Einlassventile eines Verbrennungsmotors kommt es funktionsbedingt zu einem Druckabfall im Einlasssystem. Erfindungsgemäß wird mit Hilfe von Abgasenergie dem Druckabfall beim Einlassvorgang eines Verbrennungsmotors entgegengewirkt, in dem die beim Verbrennungsmotor betriebsbedingt vorhandene Druckschwingung im Einlasssystem zur Durchführung eines thermischen Energiewandlungsprozesses benutzt wird. Die daraus resultierende pV-Arbeit wird dabei direkt durch die Kolben des Verbrennungsmotors genutzt. Dadurch kann die Verwendung einer zusätzlichen Kompressions- bzw. Expansionsmaschine (z. B. Zylinder-Kolben-Anordnung) bzw. eines elektrischen Generators zur Nutzbarmachung der Abgasenergie vermieden werden, wodurch ein besonders einfacher und kostengünstiger Aufbau der erfindungsgemäßen Vorrichtung realisierbar ist.When opening the intake valves of an internal combustion engine, there is a function-related pressure drop in the intake system. According to the invention, the pressure drop during the intake process of an internal combustion engine is counteracted with the aid of exhaust gas energy, in which the pressure oscillation in the intake system which is operationally present in the internal combustion engine is used to carry out a thermal energy conversion process. The resulting pV work is used directly by the pistons of the internal combustion engine. This makes it possible to avoid the use of an additional compression or expansion machine (for example a cylinder-piston arrangement) or an electric generator for making use of the exhaust gas energy, so that a particularly simple and cost-effective design of the device according to the invention can be realized.
Die Erfindung eignet sich insbesondere zur Teillastentdrosselung eines Ottomotors, da bei diesem im Teillastbereich der Druckabfall im Aussaugsystem besonders hoch ist.The invention is particularly suitable for partial-load throttling of a gasoline engine, since in this case the pressure drop in the suction system is particularly high in the part-load range.
