Description
Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff
des Anspruches 1.The invention relates to an internal combustion engine according to the preamble
of
Aus der DE 196 00 566 C1 ist eine mehrzylindrige Brennkraftmaschine bekannt, in deren Zylinderkurbelgehäuse ein Ölkühler für Schmieröl vorgesehen ist. Der Ölkühler liegt in einem seitlich am Zylinderkurbelgehäuse angegossenen Wasserkasten, der von Kühlwasser eines Kühlwasserkreislaufs durchströmt wird. Das Kühlwasser umströmt den Ölkühler und wird anschließend in den Zylinderkopf geführt, wo es als Kühlwassermantel an der Außenseite der Zylinder entlang geführt wird.DE 196 00 566 C1 is a multi-cylinder internal combustion engine known in their cylinder crankcase an oil cooler is provided for lubricating oil. The oil cooler is in one water box cast on the side of the cylinder crankcase, which flows through cooling water from a cooling water circuit becomes. The cooling water flows around the oil cooler and is then led into the cylinder head, where it acts as a cooling water jacket is guided along the outside of the cylinder.
Nachteilig hierbei ist, daß bei kalter Brennkraftmaschine, beispielsweise bei einem Start nach längerem Stillstand, das Schmieröl aufgrund der tiefen Temperaturen eine hohe Viskosität aufweist und wegen seiner verminderten Fließfähigkeit nicht imstande ist, die bewegten Bauteile der Brennkraftmaschine, insbesondere die Lagerstellen der Kurbelwelle und des Pleuels, in ausreichendem Maße zu schmieren.The disadvantage here is that with a cold internal combustion engine, for example when starting after a long standstill, the Lubricating oil has a high viscosity due to the low temperatures and because of its reduced fluidity is unable to move the moving components of the internal combustion engine, especially the bearings of the crankshaft and Connecting rods to lubricate sufficiently.
Ein weiteres Problem bei kaltem Motor liegt darin, daß Kraftstoff an den Zylinderwänden kondensiert, so daß das Kraftstoff/Luftverhältnis im Brennraum vom optimalen Wert abweicht und die Schadstoff-Konzentration im Abgas erhöht ist.Another problem with a cold engine is that fuel condensed on the cylinder walls so that the air / fuel ratio deviates from the optimal value in the combustion chamber and the pollutant concentration in the exhaust gas is increased.
Um dieses Problem zu umgehen, wird in der Druckschrift DE-OS 29 05 571 vorgeschlagen, das Kühlwasser mit Hilfe eines eiektrischen Heizkörpers vorzuwärmen, so daß die Zylinder von erwärmtem Kühlwasser umströmt und vorgewärmt werden. Durch diese Maßnahme soll eine bessere Startbereitschaft des Motors erreicht und außerdem Frostschäden vermieden werden. Hierbei stellt sich aber die Schwierigkeit, den Heizkörper so in das Zylinderkurbelgehäuse zu integrieren, daß einerseits eine kompakte Vorrichtung gegeben ist und andererseits auch die Möglichkeit besteht, ältere Brennkraftmaschinen, deren Zylinderkurbelgehäuse nicht zur Aufnahme eines Heizkörpers vorbereitet ist, mit geringem Aufwand nachzurüsten und dennoch eine klein bauende Vorrichtung zu erhalten.To avoid this problem, DE-OS 29 05 571 proposed the cooling water with the help of an electric Preheat radiator so that the cylinder of heated Cooling water flows around and preheated. Through this Measure is to achieve a better engine readiness and frost damage can also be avoided. in this connection but the difficulty arises in putting the radiator in that Integrate cylinder crankcase that on the one hand a compact Device is given and on the other hand, the possibility exists, older internal combustion engines, the cylinder crankcase not prepared to accommodate a radiator is to retrofit with little effort and still a small one to get building device.
Die Druckschrift DE-OS 18 02 794 offenbart eine wassergekühlte Brennkraftmaschine, in deren Kühlwasserraum eine elektrische Heizspirale zur Erwärmung des Kühlwassers eingebaut ist, wobei der Kühlwasserraum am Zylinderkurbelgehäuse angeordnet ist. Ein Ölkühler ist in der DE-OS 18 02 794 jedoch nicht genannt, so daß auch keine Maßnahmen zur Verbesserung der Fließeigenschaften von kaltem Schmieröl zur Anwendung kommen.The document DE-OS 18 02 794 discloses a water-cooled Internal combustion engine, in the cooling water room of an electric Heating coil for heating the cooling water is installed, whereby the cooling water chamber is arranged on the cylinder crankcase. On Oil cooler is not mentioned in DE-OS 18 02 794, however that also no measures to improve the flow properties of cold lubricating oil are used.
Der Erfindung liegt die Aufgabe zugrunde, die Kaltstarteigenschaften einer Brennkraftmaschine zu verbessern, wobei die erforderlichen Maßnahmen ohne Vergrößerung des Bauraums durchführbar sein sollen und eine nachträgliche Umrüstung möglich sein soll.The invention has for its object the cold start properties to improve an internal combustion engine, the required Measures can be carried out without increasing the installation space should be and a subsequent conversion possible should be.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches
1 gelöst.This object is achieved with the features of the
Der Einbau des elektrischen Heizelements in den Wasserkasten kann auch nachträglich ohne wesentliche Umbaumaßnahmen vorgenommen werden, insbesondere muß das Kurbelgehäuse nicht verändert werden. Man erhält eine vollintegrierte Kühlwasserheizung, die bereits vor dem Start zur Vorwärmung des Motors betätigbar ist und die Starteigenschaften wesentlich verbessert und auch zur Schadstoffreduzierung beiträgt. Die Kühlwasserheizung kommt praktisch ohne zusätzlichen Bauraum aus und ist leicht auch nachträglich und direkt beim Kunden zu montieren, wodurch die Einbaukosten gesenkt werden. Auch Wartungsarbeiten können schnell durchgeführt werden. Insgesamt sind die Kosten reduziert, da das Kurbelgehäuse nicht umgebaut werden muß.Installation of the electric heating element in the water tank can also be carried out retrospectively without major conversion measures in particular, the crankcase need not be changed become. You get a fully integrated cooling water heater, which can be actuated before the start to preheat the engine is and the starting properties significantly improved and also contributes to pollutant reduction. The cooling water heater comes practically without additional space and is also lightweight to be installed subsequently and directly at the customer, which means that Installation costs can be reduced. Maintenance work can also be done be done quickly. Overall, the costs are reduced since the crankcase does not have to be converted.
Ein weiterer Vorteil liegt darin, daß durch die Lage des Ölkühlers unmittelbar am Heizelement bzw. in der von dem erwärmten Kühlwasser durchfluteten Wasserkasten auch das Schmieröl erwärmt wird, wodurch die Fließeigenschaften verbessert werden. Das Schmieröl fließt leichter zu den Lagerstellen, so daß eine bessere Schmierung bewegter Bauteile erreicht wird. Der aufgeheizte Ölkühler beeinflußt wiederum das Kühlwasser, weil durch die vergrößerte Wärmeabstrahlfläche des ölkühlers das Kühlwasser schneller erwärmt wird, so daß auch die Zylinder in kürzerer Zeit vorgewärmt werden.Another advantage is that the location of the oil cooler directly on the heating element or in the heated by the Cooling water-flooded water tank also heated the lubricating oil becomes, which improves the flow properties. The lubricating oil flows more easily to the bearing points, so that a better lubrication of moving components is achieved. The heated one Oil cooler in turn affects the cooling water because of the increased heat radiation area of the oil cooler the cooling water is heated faster, so that the cylinders are shorter Time to be preheated.
Das Heizelement und der Ölkühler bilden einen Verbund, indem das Heizelement unmittelbar am Ölkühler, insbesondere durch Anlöten an die Bodenfläche des Ölkühlers, gehalten ist. Man erhält auf diese Weise ein zusammenhängendes Bauteil aus Heizelement und Ölkühler, das platzsparend ausgebildet ist und insbesondere vorgefertigt in den Wasserkasten eingesetzt bzw. für Wartungsarbeiten aus dem Wasserkasten herausgenommen werden kann.The heating element and the oil cooler form a composite by the heating element directly on the oil cooler, especially by soldering to the bottom surface of the oil cooler. You get in this way a coherent component made of heating element and oil cooler, which is designed to save space and in particular prefabricated used in the water tank or for Maintenance work can be removed from the water tank can.
Das Heizelement ist gemäß einer bevorzugten Ausführung als Heizschlange ausgebildet, wodurch die wärmeabstrahlende Oberfläche des Heizelements vergrößert ist und der Erwärmungsvorgang in kürzerer Zeit durchgeführt wird.According to a preferred embodiment, the heating element is as Heating coil formed, which creates the heat radiating surface of the heating element is enlarged and the heating process is done in less time.
Das Heizelement liegt vorteilhaft vollständig innerhalb der seitlichen Umrandung der Bodenfläche des ölkühlers, so daß die Dimensionen des Wasserkastens im wesentlichen unverändert beibehalten werden können und insbesondere die Bauhöhe des Zylinderblocks gleich bleibt; auf diese Weise wird eine besonders platzsparende Bauweise erreicht. The heating element is advantageously completely within the lateral border of the bottom surface of the oil cooler, so that the Maintain dimensions of the water tank essentially unchanged can be and in particular the overall height of the cylinder block remains the same; this way one becomes special space-saving design achieved.

2 gemäß der dargestellten Pfeilrichtung in den
Wasserkasten 4 ein und umströmt den Ölkühler 3. Ein Teil des
Kühlwassers W wird vor dem Wasserkasten 4, während der Strömung
durch den Wasserkasten und hinter dem Wasserkasten durch
Öffnungen 14 in einer Mantelwand 13 zu einem Kühlwassermantel
11 geleitet, der zwischen den Zylinderwänden 12 und der Mantelwand
13 vertikal nach unten geführt ist und die in den Zylindern
8, 9 erzeugte Wärme abführt. Die Mantelwand 13 bildet
zugleich eine Begrenzungswand des Wasserkastens 4. Zwischen
den Zylinderwänden 12 sind Kanäle 15 geschaffen, durch die
das Kühlwasser hindurchströmen kann, damit die Zylinder 8, 9
rundum gekühlt sind. Die Kanäle 15 verlaufen quer zur Längsachse
