Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einer Abgasrückführeinrichtung mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to an internal combustion engine with an exhaust gas recirculation device with the features of the preamble of claim 1.
Sie
geht von der deutschen Offenlegungsschrift
Nachteilig an der gattungsgemäßen Ausgestaltung ist, dass eine Abgasrückführung nicht im gesamten Brennkraftmaschinenkennfeld mit hohen Abgasrückführraten möglich ist.adversely on the generic embodiment is that an exhaust gas recirculation not in the entire engine map possible with high exhaust gas recirculation rates is.
Aufgabe der vorliegenden Erfindung ist es, eine Brennkraftmaschine mit einer Abgasrückführeinrichtung aufzuzeigen, mit der eine Abgasrückführung im nahezu gesamten Brennkraftmaschinenkennfeld mit hohen Abgasrückführraten möglich ist.task The present invention is an internal combustion engine with a Exhaust gas recirculation device show, with the an exhaust gas recirculation in almost the entire engine map possible with high exhaust gas recirculation rates is.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung ist eine Abgasrückführung nahezu im gesamten Brennkraftmaschinenkennfeld mit hohen Abgasrückführraten möglich. Darüber hinaus ergibt sich eine verbesserte Lebensdauer für die Abgasreinigung-, bzw. Abgasnachbehandlungsanlage, insbesondere wenn die Abgasnachbehandlungsanlage ein NOx-Speicherkat ist. Darüber hinaus ist die erfindungsgemäße Ausgestaltung in vorteilhafter Weise für Otto-Brennkraftmaschinen mit Aufladung, insbesondere im Schichtbetrieb besonders gut geeignet, da der Kraftstoffverbrauch sowie die Rohemissionen reduziert werden. Als weiterer Vorteil ist noch die besonders kompakte Bauform zu nennen.Due to the configuration according to the invention, an exhaust gas recirculation is possible almost in the entire engine map with high exhaust gas recirculation rates. In addition, there is an improved service life for the Abgasreinigung-, or exhaust aftertreatment system, especially when the exhaust aftertreatment system is a NO x -Speicherkat. In addition, the inventive design is particularly well suited for gasoline engines with supercharging, especially in stratified operation, since the fuel consumption and the raw emissions are reduced. Another advantage is the particularly compact design.
Die Ausgestaltungen gemäß den Patentansprüchen 2 bis 6 sind besonders bevorzugte Weiterbildungen der Erfindung.The Embodiments according to the claims 2 to 6 are particularly preferred developments of the invention.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispieles in vier Figuren näher erläutert.in the The following is the invention with reference to a particularly preferred embodiment explained in more detail in four figures.
Im Folgenden gelten für gleiche Bauelemente in allen Figuren die gleichen Bezugsziffern.in the The following apply to identical components in all figures the same reference numbers.
Beim
Betrieb der Brennkraftmaschine
Nach
einer Verbrennung der Frischluft mit einem Brennstoff in den Zylindern
strömt das Abgas in einen nicht bezifferten Abgaskrümmer
und weiter durch eine Turbine
Erfindungsgemäß ist
der Abgasturbolader
Die Ventile und Drosselklappen können beispielsweise konventionelle Drosselklappen, Abgasklappen, Tellerventile, Schieber, Drehschieber etc. sein.The For example, valves and throttle valves can be conventional Throttle valves, exhaust flaps, poppet valves, gate valves, rotary valves etc. be.
Besonders
bevorzugt sind die vier Ventile
Zusammengefasst ergeben sich durch die erfindungsgemäße Ausgestaltung der Brennkraftmaschine mit einer Abgasrückführeinrichtung folgende Vorteile:
- • Die Abgasrückführung ist im gesamten Brennkraftmaschinenkennfeld mit hoher Abgasrückführrate möglich.
- • Es ergibt sich eine verbesserte Lebensdauer für die Abgasreinigungsanlage, insbesondere bei Einsatz eines NOx-Speicherkatalysators und/oder eines SCR-Katalysators.
- • Die Erfindung ist insbesondere für Otto-Brennkraftmaschinen, aber auch für andere Brennverfahren, wie z. B. dem Diesel-Brennverfahren geeignet, die im Schichtbetrieb und gleichzeitig mit Abgasturboaufladung betrieben werden.
- • Weiter werden der Brennstoffverbrauch sowie die Rohemissionen reduziert.
- • Durch die Zusammenfassung des ersten Ventils
8 , des zweiten Ventils13 , des dritten Ventils15 und des vierten Ventils16 in einen einzigen Ventilblock12 wird eine extrem kompakte Bauform erzielt.
- • The exhaust gas recirculation is possible in the entire engine map with high exhaust gas recirculation rate.
- The result is an improved service life for the emission control system, in particular when using a NO x storage catalytic converter and / or an SCR catalytic converter.
- The invention is particularly for Otto internal combustion engines, but also for other combustion processes, such. B. the diesel combustion process suitable, which are operated in stratified operation and simultaneously with turbocharging.
- • Furthermore, fuel consumption and raw emissions are reduced.
- • By the summary of the first valve
8th , the second valve13 , the third valve15 and the fourth valve16 in a single Ven tilblock12 an extremely compact design is achieved.
