Abstract
Die Erfindung betrifft eine Schmierölversorgungseinrichtung für eine Brennkraftmaschine mit unterhalb eines Kurbelgehäuses angeordnetem Ölauffanggehäuse (2), in dem zwei Bauraumabschnitte (2a, 2b) für die Ölabsaugung ausgebildet sind, mit einer ersten Ölpumpe (8), durch die das Schmieröl aus dem ersten Bauraumabschnitt (2a) abgesaugt und zu den Verbrauchern der Brennkraftmaschine, wie z. B. Kurbelwellenlager, Nockenwellenlager etc., gefördert wird, und einer zweiten Ölpumpe (10), mit der das Schmieröl aus dem zweiten Bauraumabschnitt (2b) abgesaugt und in den ersten Bauraumabschnitt (2a) gefördert wird, sowie mit einem Ölkühler zur Kühlung des Schmieröls (12). DOLLAR A Es wird vorgeschlagen, dass der Ölkühler (12) im Schmierölkreislauf der zweiten Ölpumpe (10) eingebunden ist.The invention relates to a lubricating oil supply device for an internal combustion engine with an oil-collecting housing (2) arranged below a crankcase, in which two installation sections (2a, 2b) are designed for oil extraction, with a first oil pump (8) through which the lubricating oil from the first installation section (FIG. 2a) and sucked to the consumers of the internal combustion engine, such as. As crankshaft bearing, camshaft bearing, etc., is promoted, and a second oil pump (10), with which the lubricating oil from the second space section (2 b) sucked and in the first space section (2 a) is conveyed, as well as with an oil cooler for cooling the lubricating oil (12). DOLLAR A It is proposed that the oil cooler (12) is integrated in the lubricating oil circuit of the second oil pump (10).
Description
Die Erfindung betrifft eine Schmierölversorgungseinrichtung für eine Brennkraftmaschine gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a lubricating oil supply device for one Internal combustion engine according to the features of the preamble of claim 1.
In
der
Insbesondere der Ölkühler stellt einen hydraulischen Widerstand dar, der insbesondere bei niedrigen Öltemperaturen zu einem entsprechenden Druckabfall führt. Nachgeschaltete Verbraucher, wie z.B. hydraulisch verstellbare Nockenwellenversteller oder eine hydraulisch betätigbare Ventilhubumschaltung können aufgrund nicht ausreichenden Öldrucks bzw. Ölmenge nachteilig beeinflusst werden.Especially the oil cooler puts a hydraulic resistance, especially at low oil temperatures leads to a corresponding pressure drop. Downstream consumers, such as. hydraulically adjustable camshaft adjuster or a hydraulically actuated Ventilhubumschaltung can due to insufficient oil pressure or oil amount disadvantageous to be influenced.
Aufgabe der Erfindung ist es, derartige Nachteile zu vermeiden.task The invention is to avoid such disadvantages.
Die Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.The The object is achieved by the features specified in claim 1 solved.
Dadurch, dass der Ölkühler als ein wesentlicher hydraulischer Widerstand aus dem Hauptölkreislauf herausgenommen und in die zweite hintere Pumpenstufe eingebunden ist, kann die Schmierölversorgung zu den Verbrauchern verbessert werden. Neben einer besseren Schmierölversorgung der Hauptverbraucher kann die Leistungsaufnahme der beiden Ölpumpen in Summe reduziert werden, wenn über die zweite Pumpenstufe ein geringerer Ölvolumenstrom gefördert wird, da dann entsprechend der hydraulische Widerstand des Ölkühlers geringer ist. Durch die Eliminierung des Ölkühlers aus dem Öl-Hauptversorgungskreislauf kann die im Hauptstrom angeordnete Ölpumpe kleiner ausgebildet werden; die Antriebsleistung der Druckstufe reduziert sich dabei in der Größenordnung des Druckverlusts des Ölkühlers.Thereby, that the oil cooler as a significant hydraulic resistance from the main oil circuit taken out and integrated into the second rear pump stage is, can the lubricating oil supply to be improved to consumers. In addition to a better lubricating oil supply the main consumer can reduce the power consumption of the two oil pumps be reduced in total if over the second pump stage a smaller oil volume flow is promoted, because then correspondingly lower the hydraulic resistance of the oil cooler is. By eliminating the oil cooler out the main oil supply circuit For example, the oil pump arranged in the main flow can be made smaller become; the drive power of the pressure stage is reduced in the order of magnitude the pressure loss of the oil cooler.
Auf vorteilhafte Art und Weise ist der Ölkühler auf der Druckseite der zweiten Ölpumpe angeordnet.On advantageous manner, the oil cooler on the pressure side of second oil pump arranged.
Eine effektive und wirkungsvolle Kühlung ergibt sich, wenn der Ölkühler als Öl/Wasser-Plattenwärmetauscher ausgebildet ist.A effective and effective cooling arises when the oil cooler as an oil / water plate heat exchanger is trained.
Die beiden Ölpumpen sind auf vorteilhafte Art und Weise zu einer Doppelölpumpe mit zwei Pumpenstufen zusammengefasst.The two oil pumps are advantageous to a double oil pump with summarized two pump stages.
Bei einer Brennkraftmaschine mit Abgasturboaufladung, bei der das Laufwerk des Abgasturboladers (ATL) mit Schmieröl versorgt wird, kann auf vorteilhafte Art und Weise das von der ATL-Ölabsaugpumpe in den ersten Bauraumabschnitt zurück geförderte Öl ebenfalls durch den Ölkühler gekühlt werden. Dazu mündet die Druckseite der ATL-Absaugpumpe stromauf des Ölkühlers in den (Neben-) Schmierölkreislauf der zweiten Ölpumpe (zweite Druckstufe) ein.at an internal combustion engine with turbocharging, in which the drive of the exhaust gas turbocharger (ATL) is supplied with lubricating oil, can be advantageous Way that from the ATL oil suction pump Oil pumped back into the first space section is also cooled by the oil cooler. To this ends the pressure side of the ATL suction pump upstream of the oil cooler in the (secondary) lubricating oil circuit the second oil pump (second pressure level).
