Abstract

The i.c. engine with several inlet valves has associated passages per cylinder, the first passage connecting to an exhaust gas return system (10), and the second passages fitted with a fresh gas turbulence system (9). The exhaust return and turbulence system passage issue at similar eccentricity in their respective inlet ducts (2,3). The passages are pref. lines which issue close to the inlet valve on the same side of the adjacent inlet passages.

Description

Die Erfindung betrifft eine Hubkolben-Brennkraftmaschine mit zumindest zwei Einlaßventilen und zugeordneten Ein­ laßkanälen je Zylinder, wobei der erste Einlaßkanal mit einem Abgasrückführsystem in Verbindung steht und der zweite Einlaßkanal ein Frischgas-Turbulenzsystem auf­ weist.The invention relates to a reciprocating piston internal combustion engine with at least two inlet valves and associated one let channels per cylinder, the first inlet channel with is connected to an exhaust gas recirculation system and the second inlet channel on a fresh gas turbulence system points.

Eine derartige Brennkraftmaschine ist aus der DE 38 28 742 A1 bekannt. Das Turbulenzsystem erzeugt dabei - wie an sich bekannt - eine Verwirbelung der in den Zylinder bzw. in den Brennraum der Brennkraftmaschine eingeführten Gase. Über das Abgasrückführsystem hingegen werden - wie ebenfalls bekannt - mehr oder minder große Mengen von Ab­ gas zum Frischgas hinzugefügt.Such an internal combustion engine is known from DE 38 28 742 A1 known. The turbulence system creates - how known per se - a swirling in the cylinder or introduced into the combustion chamber of the internal combustion engine Gases. On the other hand, the exhaust gas recirculation system - how also known - more or less large amounts of Ab gas added to the fresh gas.

Der Erfindung liegt die Aufgabe zugrunde an einer gattungsgemäßen Brenn­ kraftmaschine die sich einstellenden Turbulenzen weiter zu erhöhen.The invention is based on a generic Brenn the task engine continues the turbulence to increase.

Hierzu hat die Erfindung erkannt, daß zusätz- lich der zugeführte Abgasstrom zur Turbulenzerzeugung herangezogen werden kann.To this end, the invention has recognized that additional Lich the supplied exhaust gas flow for turbulence generation can be used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Abgasrückführsystem und das Frischgas­ Turbulenzsystem als im jeweiligen Einlaßkanal glei­ chermaßen exzentrisch mündende Kanäle ausgebildet sind.This object is achieved according to the invention solved in that the exhaust gas recirculation system and the fresh gas  Turbulence system as the same in the respective inlet duct channels are formed which are eccentric.

Erfindungsgemäß führt somit sowohl das über das Turbu­ lenzsystem zugeführte Frischgas, als auch das über das Abgasruckführsystem zugeführte Abgas zu einer gleichsin­ nigen Verwirbelung der in den Brennraum bzw. Zylinder der Brennkraftmaschine eingeführten Gasmenge. Zur Erzielung dieser Gleichsinnigkeit münden dabei die das Abgas bzw. das zusätzliche Frischgas führenden Kanäle jeweils glei­ chermaßen exzentrisch in den Haupt-Einlaßkanalen. Insbe­ sondere sind diese Kanäle des Abgasrückführsystemes sowie des Frischgas-Turbulenzsystemes als Leitungen beispiels­ weise in Form eingebrachter Rohrstücke ausgebildet, die in den im wesentlichen parallel nebeneinanderliegenden Einlaßkanälen beispielsweise jeweils in deren rechten Seitenbereichen münden. Eine besonders gut ausgeprägte Verwirbelung wird dabei erzielt, wenn diese Leitungen nahe der jeweiligen Einlaßventile münden.According to the invention, this leads to both the Turbu fresh gas supplied as well as that via the Exhaust gas recirculation system supplied exhaust gas at the same time some turbulence in the combustion chamber or cylinder of the Internal gas quantity imported. To achieve this coincidence leads to the exhaust gas or the channels carrying additional fresh gas are the same eccentrically in the main inlet channels. In particular special are these channels of the exhaust gas recirculation system as well the fresh gas turbulence system as lines for example wise in the form of inserted pipe pieces, the in those essentially parallel to each other Inlet channels, for example, each in the right Side areas open. A particularly good one Whirling is achieved when these lines close to the respective inlet valves.

Die Ansprüche 3 bis 5 beschreiben vorteilhafte Weiterbil­ dungen an einer erfindungsgemäßen mehrzylindrigen Hubkol­ ben-Brennkraftmaschine. So können im Hinblick auf eine einfache konstruktive Ausgestaltung sowie eine verein­ fachte Steuerung die Kanäle des Abgasrückführsystemes so­ wie des Frischgas-Turbulenzsystemes jeweils von einem zu­ geordneten Sammelbehälter versorgt werden. Um dabei auch über das Frischgas-Turbulenzsystem, das beispielsweise im Leerlaufbetrieb der Brennkraftmaschine alleinig für die Zufuhr von Frischgas verantwortlich sein kann, auch gut aufbereiteten Brennstoff in den Zylinder bzw. Brennraum der Brennkraftmaschine einleiten zu können, mündet in diesen Sammelbehalter eine Vorrichtung zur Zufuhr dampf­ förmigen Kraftstoffes. Im einfachsten Fall kann hierzu beispielsweise eine beheizbare Kraftstoffkammer vorgese­ hen sein. Im Sinne einer Funktionsvereinigung ist es je­ doch besonders vorteilhaft, die Spülleitung beispiels­ weise eines Aktivkohlefilters zur Aufnahme von Kraft­ stoffdämpfen aus einem Fahrzeugtank in den Sammelbehälter des Frischgas-Turbulenzsystemes münden zu lassen.Claims 3 to 5 describe advantageous developments on a multi-cylinder reciprocating piston according to the invention ben internal combustion engine. So with regard to a simple design and a club fold control the channels of the exhaust gas recirculation system like the fresh gas turbulence system from one to each orderly collection containers are supplied. To do it too about the fresh gas turbulence system, for example in the Idle operation of the internal combustion engine solely for that Fresh gas supply may also be responsible processed fuel in the cylinder or combustion chamber to be able to initiate the internal combustion engine leads to this collecting container a device for supplying steam shaped fuel. In the simplest case, this can be done for example, a heatable fuel chamber hen. In the sense of a functional association, it is ever  but particularly advantageous, the flush line, for example as an activated carbon filter to absorb power vapors from a vehicle tank into the collection container of the fresh gas turbulence system.

Die im folgenden erläuterte Prinzipskizze stellt ein be­ vorzugtes Ausführungsbeispiel der Erfindung dar.The schematic diagram explained below represents a be preferred embodiment of the invention.

Eine mehrzylindrige Hubkolben-Brennkraftmaschine besteht aus drei Zylindern 1a, 1b, 1c, denen über Einlaßkanäle 2, 3 (2a, 3a, 2b, 3b, 2c, 3c) Frischgas zugeführt wird. Das verbrannte Gas gelangt als Abgas über die Auslaßkanäle 4, 5 (4a, 5a, 4b, 5b, 4c, 5c) aus den Zylindern 1. Die Über­ trittsöffnungen der Einlaßkanäle 2, 3 bzw. der Aus­ laßkanäle 4, 5 in die Zylinder 1 sind wie bekannt mit Einlaßventilen 6 bzw. Auslaßventilen 7 verschließbar.A multi-cylinder reciprocating internal combustion engine consists of three cylinders 1 a, 1 b, 1 c, to which fresh gas is supplied via inlet channels 2 , 3 ( 2 a, 3 a, 2 b, 3 b, 2 c, 3 c). The burned gas arrives as exhaust gas from the cylinders 1 via the outlet channels 4 , 5 ( 4 a, 5 a, 4 b, 5 b, 4 c, 5 c). The via openings of the inlet channels 2 , 3 and from lasskanäle 4 , 5 in the cylinder 1 are known to be closed with inlet valves 6 and 7 exhaust valves.

Die Einlaßkanäle 2, 3 werden über eine Sauganlage 8 mit Frischgas versorgt. Neben dem über diese Sauganlage 8 zu­ geführten Frischgas kann jedoch weiteres Frischgas über sog. Turbulenz-Kanäle 9 zu den einzelnen Zylindern 1a bis 1c gelangen. Daneben wird den Zylindern 1a bis 1c auch Abgas zugeführt; hierzu ist ein Abgas-Rückführsystem vor­ gesehen, von dem im wesentlichen nur die Abgasrückführ- Kanäle 10 dargestellt sind. Wahrend die Turbulenz-Kanäle 9 mit einem ersten Sammelbehälter 11 verbunden sind, wer­ den die Abgasrückführ-Kanäle 10 von einem zweiten Sammel­ behälter 12 versorgt.The inlet channels 2 , 3 are supplied with fresh gas via a suction system 8 . In addition to the fresh gas to be supplied via this suction system 8 , however, further fresh gas can reach the individual cylinders 1 a to 1 c via so-called turbulence channels 9 . In addition, exhaust gas is also supplied to the cylinders 1 a to 1 c; for this purpose, an exhaust gas recirculation system is seen before, of which essentially only the exhaust gas recirculation channels 10 are shown. While the turbulence channels 9 are connected to a first collecting tank 11 , who supplies the exhaust gas recirculation channels 10 from a second collecting tank 12 .

Jeder Turbulenz-Kanal 9 sowie jeder Abgasrückführ-Kanal 10 mündet in seinem zugeordneten Einlaßkanal 2 bzw. 3 gleichermaßen exzentrisch. Die Mündungsstelle des Kanales 9 bzw. 10 liegt dabei nahe des Einlaßventiles 6 jeweils an der rechten Seitenwand des Einlaßkanales 2 bzw. 3. Mit dieser Anordnung stellt sich in den einzelnen Zylin­ dern 1a bis 1c ein ausgeprägter Drall des eingebrachten Gases ein, der im wesentlichen von den Gasströmen, die aus den gleichermaßen exzentrisch mündenden Kanälen 9, 10 austreten, erzeugt wird.Each turbulence channel 9 and each exhaust gas recirculation channel 10 likewise open eccentrically in its associated inlet channel 2 or 3 . The mouth of the channel 9 or 10 is close to the inlet valve 6 on the right side wall of the inlet channel 2 or 3rd With this arrangement, there is a pronounced swirl of the introduced gas in the individual cylinders 1 a to 1 c, which is essentially generated by the gas streams that emerge from the equally eccentrically opening channels 9 , 10 .

Während der Sammelbehälter 12 des Abgasrückführsystemes über eine nicht gezeigte Leitung - in dieser befindet sich ein Durchsatzregelventil - mit der Abgasanlage und somit den Auslaßkanälen 4, 5 verbunden ist, mündet im Sammelbehälter 11 für das Frischgas eine nicht gezeigte Frischgas-Zufuhrleitung, die beispielsweise stromab eines Luftfilters vom Luftansaugsystem der Brennkraftmaschine abzweigt. Zusätzlich wird dem Sammelbehälter 11 noch gas­ förmiger Kraftstoff zugeführt. Hierzu mündet in den Sam­ melbehälter 11 die Verbindungsleitung einer beheizbaren Kraftstoffkammer (nicht gezeigt). Somit ist es beispiels­ weise möglich, im Leerlaufbetrieb der Brennkraftmaschine den einzelnen Zylindern 1 Frischgas lediglich über die Turbulenz-Kanäle 9 zuzuführen. Da der Kraftstoff im Sam­ melbehalter 11 in dampfförmigem Zustand vorliegt, ist eine optimale Gemischaufbereitung gewährleistet.During the collection container 12 of the exhaust gas recirculation system via a line not shown - in that there is a flow control valve - with the exhaust system and thus the outlet channels 4, 5 is connected, opens in the collecting tank 11 for fresh gas, a fresh gas supply line, not shown, downstream, for example, a Air filter branches from the air intake system of the internal combustion engine. In addition, the collecting container 11 is also supplied with gaseous fuel. For this purpose, the connecting line of a heatable fuel chamber (not shown) opens into the collecting tank 11 . It is thus possible, for example, to supply fresh gas to the individual cylinders 1 only via the turbulence channels 9 when the internal combustion engine is idling. Since the fuel in the Sam melbehalter 11 is in the vapor state, an optimal mixture preparation is guaranteed.

Darüber hinaus kann mit der gezeigten Anordnung in kon­ struktiv einfacher Weise eine optimale Drallbewegung der in die einzelnen Zylinder eingebrachten Gase erzeugt wer­ den.In addition, with the arrangement shown in con structurally simple way an optimal swirl movement of the Gases introduced into the individual cylinders are generated the.
