Description
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere eine Dieselbrennkraftmaschine mit zumindest einem Zylinder und einem darin geführten über eine Pleuelstange auf eine Kurbelwelle einwirkenden Kolben, einem Zylinderkopf mit durch Ventiltriebe betätigten Gaswechselventilen und mindestens einem Drallkanal zur Zuführung von Ladeluft aus einem Luftzuführsystem, einem Abgassystem, einem im Boden des Kolbens befindlichen Brennraum und einer direkt in den Brennraum spritzenden Kraftstoffeinspritzdüse sowie mit Mitteln zur Beeinflussung des Ladeluftdralls.The The invention relates to an internal combustion engine, in particular a diesel internal combustion engine with at least one cylinder and a guided over a connecting rod on a Crankshaft acting piston, a cylinder head with valve trains actuated Gas exchange valves and at least one swirl duct for the supply of Charge air from an air supply system, an exhaust system, a combustion chamber located in the bottom of the piston and a directly injecting into the combustion chamber fuel injector and with means for influencing the charge air swirl.
Mit
Nachteilig dabei ist, dass insbesondere bei geringer Drehzahl der Brennkraftmaschine lediglich eine vergleichsweise geringe Drallintensität erzielt werden kann. Diese geringe Drallintensität verliert beim Verdichtungshub weiter an Energie, so dass bei Einspritzung des Kraftstoffes nicht mehr die für die Kraftstoffverteilung und den Brennverlauf gewünschte Ladungsbewegung vorliegt.adversely It is that, in particular at low speed of the internal combustion engine only a relatively small swirl intensity can be achieved. This low swirl intensity loses energy during the compression stroke, so that when injected the fuel is no longer the fuel distribution and the burning process desired Charge movement is present.

Bei Brennkraftmaschinen mit ventilgesteuerten Ein- und Auslasskanälen sind solche Einlassschlitze nicht bekannt.at Internal combustion engines with valve-controlled inlet and outlet channels are such inlet slots are not known.
Der Erfindung liegt die Aufgabe zugrunde, eine Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruches 1 so zu verbessern, dass ein von den im Zylinderkopf befindlichen Einlasskanälen, insbesondere einem Drallkanal initiierter Ladungsdrall im Zylinder für den Verdichtungshub in geregelter Weise stabilisiert oder verstärkt werden kann. Of the Invention is based on the object, an internal combustion engine according to the preamble of To claim 1 to improve so that one of the cylinder head located inlet channels, in particular a swirl channel initiated charge twist in the cylinder for the compression stroke can be stabilized or strengthened in a regulated manner.
Die Erfindung löst diese Aufgabe mit den kennzeichnenden Merkmalen des Patentanspruches 1. Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Gegenstand.The Invention solves This object with the characterizing features of claim 1. The dependent claims have advantageous developments of the invention the subject.
Der nach dem Ansaugtakt im unteren Totpunkt kurzzeitig verharrende Kolben gibt eine oder mehrere Öffnungen eines Kanals frei, über den durch eine Druckluftquelle ein Luftstrom tangential in den Zylinderraum gebracht wird. Dieser Luftstrom kann in Abhängigkeit von Motorparametern wie Z. B. Drehzahl, Last, Kraftstoffqualität, Außenluftdruck und dergleichen durch eine elektronische Steuereinheit sowie ein Regelventil zumessbar sein.Of the after the intake stroke at bottom dead center briefly persistent piston gives one or more openings a channel, over through a compressed air source, an air flow tangentially into the cylinder chamber is brought. This airflow may be dependent on engine parameters such as speed, load, fuel quality, outside air pressure, and the like by an electronic control unit and a control valve zumessbar be.
Die durch die Öffnungen in der Zylinderwand einströmende Luft verstärkt den Drall der Ladung im Zylinder. Der Querschnitt der Öffnungen kann dafür relativ klein gehalten sein. Insbesondere für direkteinspritzende Dieselmotoren wird es vorteilhaft sein, wenn sich an die Öffnungen in der Zylinderwand ein Kanal im Kolben zu dem im Kolbenboden befindlichen Brennraum fortsetzt und dort tangential austritt. Damit gelingt es, gezielt den Drall in der Kolbenmulde zu unterstützen.The through the openings flowing in the cylinder wall Air amplified the spin of the charge in the cylinder. The cross section of the openings can be relative for that be kept small. Especially for direct injection diesel engines it will be advantageous if the openings in the cylinder wall a channel in the piston to the combustion chamber located in the piston head continue and exit there tangentially. This succeeds, purposefully to support the twist in the piston recess.
Bei Brennkraftmaschinen mit einem Ladegebläse bietet es sich an, als Druckluftquelle das Ladegebläse zu nutzen. Dabei kann dieses Ladegebläse auch der Verdichter eines Abgasturboladers sein.at Internal combustion engines with a charge blower, it makes sense, as a compressed air source the charging fan to use. This charger can also be the compressor of a Be exhaust gas turbocharger.
Die Druckluftquelle kann jedoch auch von einer Luftpumpe bzw. einem Gebläse gebildet sein, welches ent weder direkt von der Brennkraftmaschine angetrieben ist oder einen separaten Antrieb, z. B. durch einen Elektromotor aufweist. The However, compressed air source can also by an air pump or a fan be formed, which ent neither driven directly by the internal combustion engine is or a separate drive, z. B. by an electric motor having.
Eine solche Luftpumpe kann z. B. kombiniert werden mit einer ohnehin vorhandenen Zusatzluftpumpe für die während der Katalysatoraufheizzeit erfolgende Zumischung von Luft zum Abgas.A Such air pump can, for. B. be combined with an anyway existing additional air pump for the while the Katalysatoraufheizzeit taking place mixing of air to the exhaust gas.
Es kann aber auch zweckmäßig sein, für die Bereitstellung der Druckluft eine gesonderte elektrisch angetriebene Pumpe vorzusehen. Als Vorteil elektrisch angetriebener Pumpen ist die relativ einfache Regelung der Pumpleistung über die Drehzahl zu sehen.It but it can also be useful for the provision the compressed air to provide a separate electrically driven pump. As an advantage of electrically driven pumps is relatively simple Control of pump power over to see the speed.
Über den tangential in den Zylinder einmündenden Kanal kann der Zylinderladung auch Abgas zugeführt werden, wenn sich zur Beeinflussung des Abgasverhaltens der Brennkraftmaschine eine Abgasrückführung erforderlich macht. Das Abgas kann der im Kanal geführten Luft beigemischt werden. Die Beimischungsrate ist dabei frei wählbar zwischen 0 und 100 %. Als ein besonderer Vorteil ergibt sich dadurch, dass die im rückgeführten Abgas mitgeführten Partikel die Ansaugwege im Zylinderkopf nicht verschmutzen können.On the tangentially opening into the cylinder Channel can also be supplied to the cylinder charge exhaust, if to influence the exhaust behavior of the internal combustion engine exhaust gas recirculation required power. The exhaust gas can be added to the air guided in the channel. The admixture rate is freely selectable between 0 and 100%. As a particular advantage results from the fact that in the recirculated exhaust entrained particles can not pollute the intake passages in the cylinder head.
