Description
Die Erfindung bezieht sich auf Verbrennungskraftmaschinen mit Vorrichtungen zum Einblasen von Sekundärluft. Das Einblasen erfolgt bei Verbrennungskraftmaschinen mit Abgasturbolader mit dem über die Abgasturbine angetriebenen Verdichter. Der Verdichter im Lufteinlasskanal steht zum Einblasen von Sekundärluft mit seiner Druckseite über einen Sekundärkanal mit dem Abgaskanal in Verbindung.The invention relates to internal combustion engines with devices for injecting secondary air. The injection takes place in internal combustion engines with turbocharger with the over the Exhaust gas turbine driven compressor. The compressor in the air inlet duct stands for the injection of secondary air with its print side over one secondary channel in communication with the exhaust duct.

Einblasen von Sekundärluft

Beim Start einer Verbrennungskraftmaschine mit Abgasturbolader ist es abgesehen von den zu überwindenden Druckunterschieden zwischen Zuluft- und Abgasseite schwierig, die Sekundärluft vom Luftmassenstrom abzuzweigen, da in den beim Start einer Verbrennungskraftmaschine gefahrenen Kennpunkten das Gebläse oder der Verdichter nur einen unzureichenden Luftmassenstrom fördern kann. Neben den niedrigen Drehzahlen der Verbrennungskraftmaschine beim Start tritt hinsichtlich der erforderlichen Menge an Sekundärluft in der dem Start folgenden Warmlaufphase der nachteilige Effekt hinzu, dass der Katalysator noch keine optimale Betriebstemperatur erreicht hat. Während der Warmlaufphase ist deshalb eine größere Menge an Sekundärluft notwendig, um eine optimale Abgasnorm zu erfüllen.At the start of an internal combustion engine with turbocharger, it is apart from the pressure differences to be overcome between supply air and exhaust side difficult, the secondary air from the air mass flow branch off, as in the start of an internal combustion engine driven characteristics the blower or the compressor can only deliver an insufficient mass air flow. In addition to the low speeds of the internal combustion engine Start occurs in terms of the required amount of secondary air in the warm-up phase following the start, the disadvantageous effect that the catalyst has not yet reached an optimal operating temperature Has. While the warm-up phase therefore requires a larger amount of secondary air, to meet an optimal emission standard.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbrennungskraftmaschine mit einer Vorrichtung zum Einblasen von Sekundärluft derart auszubilden und anzuordnen, dass beim Start und Warmlauf der Verbrennungskraftmaschine der zur Verfügung stehende Luftmassenstrom maximiert wird, damit ausreichend Sekundärluft zum Einblasen in den Abgasstrom zur Verfügung steht.The invention is based on the object Internal combustion engine with a device for blowing in secondary air such form and arrange that at the start and warm-up the combustion engine of the available air mass flow is maximized, so that sufficient secondary air for blowing into the exhaust stream to disposal stands.
Gelöst wird die Aufgabe erfindungsgemäß dadurch, dass der Verdichter eines Abgasturboladers im Lufteinlasskanal der Verbrennungskraftmaschine zum Einblasen von Sekundärluft über einen Sekundärkanal vorgesehen ist. Der Sekundärkanal verbindet den Lufteinlasskanal mit dem Abgaskanal. Der Verdichter bzw. der Abgasturbolader ist hierzu sekundär mittels eines Elektromotors angetrieben. Der primäre Antrieb erfolgt durch den Abgasstrom über die Abgasturbine. Mittels des Elektromotors ist jede beliebige Drehzahl unabhängig von der Drehzahl der Verbrennungskraftmaschine einstellbar.The problem is solved according to the invention by that the compressor of an exhaust gas turbocharger in the air intake passage of Internal combustion engine for injecting secondary air over a secondary channel is provided. The secondary channel connects the air inlet duct to the exhaust duct. The compressor or the exhaust gas turbocharger is for this purpose secondarily by means of an electric motor driven. The primary Drive takes place through the exhaust gas flow through the exhaust gas turbine. through The electric motor is independent of any speed the speed of the internal combustion engine adjustable.
Eine weitere Möglichkeit für Verbrennungskraftmaschinen ohne Abgasturbolader besteht in der Anordnung eines Gebläses im Lufteinlasskanal, das ebenso wie der Abgasturbolader mittels eines Elektromotors angetrieben wird.Another option for internal combustion engines without turbocharger consists in the arrangement of a fan in the air inlet duct, as well as the exhaust gas turbocharger driven by an electric motor becomes.
Hierdurch wird erreicht, dass der Sekundärluftmassenstrom über einen Sekundärkanal an den Einblasstellen eingebracht und beliebig, unabhängig von der Drehzahl der Verbrennungskraftmaschine eingestellt werden kann. Aufgrund der räumlichen Nähe des Abgasturboladers oder Gebläses zur Einblasstelle der Sekundärluft am Abgaskrümmer werden Drosselverluste vermieden.This ensures that the Secondary air mass flow over one secondary channel introduced at the injection points and arbitrary, regardless of the speed of the internal combustion engine can be adjusted. Due to the proximity of the exhaust gas turbocharger or blower to the injection point of the secondary air on the exhaust manifold throttling losses are avoided.
Bei Verbrennungskraftmaschinen mit Abgasturboladern erzeugt beim erfindungsgemäßen Sekundärantrieb des Abgasturboladers die Abgasturbine ein zum Einblasen günstiges Druckverhältnis im Abgaskanal zwischen Abgasturbine und Einblasstelle. Die Abgasturbine arbeitet in diesem Fall im Saugbetrieb.In internal combustion engines with Exhaust gas turbochargers generated in the secondary drive according to the invention of the exhaust gas turbocharger the exhaust gas turbine for blowing a favorable pressure ratio in the exhaust duct between the exhaust gas turbine and the injection point. The exhaust gas turbine works in this case in suction mode.
Eine zusätzliche Möglichkeit ist gemäß einer Weiterbildung, dass stromab im Lufteinlasskanal der Verbrennungskraftmaschine der Verdichter vor der Drosselklappe angeordnet ist und der Sekundärkanal zwischen dem Verdichter und der Drosselklappe vom Lufteinlasskanal abzweigt. Der Verdichter des Abgasturboladers oder des Gebläses fördert somit den gesamten Luftmassenstrom je nach momentanem Bedarf an Verbrennungsluft und Sekundärluft. Der über den Lufteinlasskanal den Zylindern zugeführte Luftmassenstrom wird über die Drosselklappe geregelt.An additional possibility is according to a development, that downstream of the air intake duct of the internal combustion engine of the Compressor is arranged in front of the throttle and the secondary channel between the compressor and the throttle valve branches off the air inlet duct. The compressor of the exhaust gas turbocharger or the blower thus promotes the total air mass flow depending on the momentary demand for combustion air and secondary air. The over the air inlet duct to the cylinders supplied air mass flow is over the Throttle regulated.
Der Sekundärkanal verläuft entlang der Zylinder und verzweigt stromab an den Auslass eines jeden Zylinders. Der Sekundärluftmassenstrom wird über ein regelbares Ventil innerhalb des Sekundärkanals geregelt.The secondary channel runs along the cylinder and Branches downstream to the outlet of each cylinder. The secondary air mass flow will over a controllable valve regulated within the secondary channel.
Ferner ist es vorteilhaft, dass in den Sekundärkanal neben dem regelbaren Ventil stromab folgend vor dem ersten Zylinder mindestens ein Rückschlagventil eingebracht ist. Das Rück schlagventil schließt bei abgasseitigem Überdruck und verhindert eine unkontrollierte Abgasrückführung.Furthermore, it is advantageous that in the secondary channel next to the controllable valve downstream following the first cylinder at least one check valve is introduced. The return check valve closes at exhaust gas pressure and prevents uncontrolled exhaust gas recirculation.
Vorgesehen ist hierzu auch, dass für jeden Zylinder der Verbrennungskraftmaschine stromab nach den Auslassventilen in den Abgaskanal eine Einblasstelle für Sekundärluft eingebracht ist. Der Sekundärkanal mündet in Strömungsrichtung des Abgases nach dem jeweiligen Auslassventil in den durch die Abgaskrümmer gebildeten Abgaskanal. Alternativ ist eine gemeinsame Einblasstelle im Abgaskanal stromab nach dem letzten Zylinder vorgesehen.It is also provided for this purpose that a Einblasstelle for secondary air is introduced downstream of the exhaust valves in the exhaust duct for each cylinder of the internal combustion engine. Of the Secondary channel opens in the flow direction of the exhaust gas after the respective exhaust valve in the exhaust passage formed by the exhaust manifold. Alternatively, a common injection point in the exhaust duct is provided downstream of the last cylinder.
Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Lösung ist schließlich vorgesehen, dass der Sekundärkanal und die Einblasstellen durch das Gehäuse der Verbrennungskraftmaschine gebildet sind. Die Montage der Verbrennungskraftmaschine ist dadurch wesentlich vereinfacht. Eine ähnliche Vereinfachung ergibt sich, wenn ein Teil der Gehäusewand der Verbrennungskraftmaschine als Sekundärkanal gebildet ist.According to a preferred embodiment of inventive solution in the end provided that the secondary channel and the injection points through the housing of the internal combustion engine are formed. The assembly of the internal combustion engine is characterized considerably simplified. A similar Simplification arises when a part of the housing wall of the internal combustion engine as a secondary channel is formed.
Von besonderer Bedeutung ist für die vorliegende Erfindung, dass die Verbindung zwischen Lufteinlasskanal und Sekundärkanal als regelbares Dreiwegeventil ausgebildet ist. Das Dreiwegeventil ersetzt das regelbare Ventil im Sekundärkanal und die Drosselklappe im Lufteinlasskanal.Of particular importance for the present Invention that the connection between the air inlet duct and the secondary duct as adjustable three-way valve is formed. The three-way valve replaces the controllable valve in the secondary channel and the throttle in the air intake duct.
Im Zusammenhang mit der erfindungsgemäßen Ausbildung und Anordnung ist es von Vorteil, dass der Verdichter bzw. das Verdichterrad des Abgasturboladers oder des Gebläses unterschiedlich ausgebildet ist. Der Verdichter kann als reiner Radialverdichter oder als reiner Axialverdichter ausgebildet sein. Ebenso können kombinierte Radial- und Axialverdichter zum Einsatz kommen. Je nach Ausbildung des Verdichters weist dieser Drossel- und/oder Leitvorrichtungen im Ein- und Auslassbereich des Verdichtergehäuses auf. Durch Verstellen der Drossel- und Leitvorrichtungen wird die Regelung der Sekundärlufteinblasung beeinflusst.In connection with the training according to the invention and arrangement, it is advantageous that the compressor or the compressor wheel the exhaust gas turbocharger or the blower designed differently is. The compressor can be used as a pure centrifugal compressor or as a cleaner Axial compressor be formed. Similarly, combined radial and Axial compressors are used. Depending on the design of the compressor has this throttle and / or guide devices in the inlet and outlet of the compressor housing on. By adjusting the throttle and Leitvorrichtungen is the Control of secondary air injection affected.
Vorteilhaft ist es ferner, dass das Drehmoment des Elektromotors über eine regelbare Kupplung auf die ATL-Welle des Abgasturboladers übertragen wird. Je nach Bedarf ist der Elektromotor zu- oder abschaltbar.It is also advantageous that the Torque of the electric motor over a controllable clutch transmitted to the ATL shaft of the turbocharger becomes. Depending on requirements, the electric motor can be switched on or off.
Beim Einsatz eines Gebläses ist es entsprechend vorteilhaft, dass das Drehmoment des Elektromotors über eine regelbare Kupplung auf eine Antriebswelle des Gebläses übertragen wird. Auch hier ist je nach Bedarf der Elektromotor zu- oder abschaltbar.When using a blower is it is correspondingly advantageous that the torque of the electric motor via a transferable clutch to a drive shaft of the blower becomes. Here as well, the electric motor can be switched on or off as required.
