TITEL:TITLE:
Brennkraftmaschine mit reduzierter Schall- und WärmeemissionInternal combustion engine with reduced noise and heat emissions
Die Erfindung bezieht sich auf eine ölgekühlte Kolbenbrennkraftmaschine mit freistehenden Zylindern und geringen Emissionswerten von Wärme, Schall und Schadstoffen.The invention relates to an oil-cooled piston internal combustion engine with free-standing cylinders and low emissions of heat, noise and pollutants.
Die Gleichung Kühlung gleich Aufheizung muß für alle Brennkraftmaschinen stimmen. Was von einem künftigen Motor aber verlangt wird, ist, daß die Wärmeemission möglichst klein gehalten wird. Wärmeverluste, die nicht vermeidbar sind, sollen außerdem mit einem möglichst hohen Temperaturniveau einer nützlichen Verwendung, wie z. B. einer Kabinenheizung, zugeführt werden. Da Kühlwasser bei relativ niedriger Temperatur kocht und Kühlluft wegen ihrer Verunreinigung am Motor für viele Zwecke unbrauchbar wird, besteht Veranlassung, das Motorenöl als Kühlmittel heranzuziehen. Aus diesem Grund gab es schon immer Versuche, Motorenteile, wie Kolben, Zylinder und Zylinderkopf, mit Ölkammern zu versehen.The equation cooling equals heating must be used for all internal combustion engines voices. What is required of a future engine, however, is that the heat emission is kept as small as possible. Heat losses that are unavoidable should also be useful with the highest possible temperature level, such as B. a cabin heater are supplied. Because cooling water boils at a relatively low temperature and cooling air because of their contamination on the engine becomes unusable for many purposes, there is a reason to use the engine oil as a coolant. For this reason, there have always been attempts to equip engine parts, such as pistons, cylinders and cylinder heads, with oil chambers.
um die anfallende Abwärme im Öl aufzufangen (z.B. DE 26 49 562) Aus Gründen, die in den thermischen Eigenschaften des Öls liegen, ging dabei die Gleichung Aufheizung gleich Kühlung nur bei geringer Aufheizung, also kleiner Motorleistung, auf.to collect the resulting waste heat in the oil (e.g. DE 26 49 562) For reasons related to the thermal properties of the oil, the equation heating equals cooling only worked with low heating, i.e. low engine power.
Wesentlich höhere Motorenleistungen mit reiner Ölkühlung wurden erreicht, wenn der Kolben und das Brennverfahren so gestaltet sind, daß nur wenig Wärme aus dem Brennraum an die Zylinderwand fließen kann (DE 33 14 543). Allerdings ergibt sich auch hier eine Leistungsbegrenzung dieser Ölkühlung dadurch, daß die Kühlung im wesentlichen nur guer zur Kurbelwellenlage wirksam ist. Im Längsschnitt des Motors ist eine solche Kühlung nicht wirksam, weil die im Kolbenunterteil angeordneten Umlenkschaufeln für das Kühlöl nur in einer Richtung wirken. Die innere Kühlung ist damit nicht gleichmäßig auf den Umfang verteilt. Auch die äußere Kühlung ist nicht am ganzen Zylinderumfang wirksam, da die Zylinder zusammengegossen sind. In Längsrichtung der Kurbelwelle hat diese Konstruktion sowohl innere wie äußere Kühlungsmängel .Much higher engine outputs with pure oil cooling were achieved when the piston and the combustion process are so designed are that only little heat can flow from the combustion chamber to the cylinder wall (DE 33 14 543). However, it also arises here a power limitation of this oil cooling in that the cooling is essentially only effective for the crankshaft position. Such cooling is not effective in the longitudinal section of the motor, because the deflecting vanes for the cooling oil, which are arranged in the lower part of the piston, only work in one direction. The inner cooling is therefore not evenly distributed over the circumference. The external cooling is also not effective on the entire circumference of the cylinder, because the cylinders are cast together. In the longitudinal direction of the crankshaft, this design has both internal and external cooling deficiencies .
Um auch in dieser Beziehung den ölgekühlten Motor zu optimieren, wird erfindungsgemäß vorgeschlagen, die innere Ölkühlung von Zylinder und Kolben dadurch zu verbessern, daß im Kolbenunterteil der Rückfluß des hochgespritzten Kühlöls um 90 i ° umgelenkt wird, was eine wesentliche Verbesserung in der thermischen Rundheit des Zylinders bringt.In order to optimize the oil-cooled engine in this respect as well, it is proposed according to the invention that the internal oil cooling of To improve the cylinder and piston by diverting the return flow of the sprayed-up cooling oil by 90 i ° in the lower part of the piston which brings a significant improvement in the thermal roundness of the cylinder.
Die äußere Kühlung des Zylinders wird dadurch verbessert, daß die Zylinder freistehend in den ölbespritzten Raum des Motors einbezogen werden. Erreicht wird dies dadurch, daß die Zylinder in V-Stellung angeordnet werden und mit einem gemeinsamen Deckel für beide Zylinderreihen abgedeckt sind. Dieser Deckel ersetzt die üblichen Zylinderkopfdeckel, so daß alles Öl, das für Ventilsteuerung und Kopfkühlung dient, zusätzlich der äußeren Zylinderkühlung zugute kommt.The external cooling of the cylinder is improved by the fact that the cylinder is free-standing in the oil-splashed space of the engine be included. This is achieved in that the cylinders are arranged in a V-position and with a common cover are covered for both rows of cylinders. This cover replaces the usual cylinder head cover, so that all oil is used for valve control and head cooling, the outer cylinder cooling also benefits.
Auch der am oberen Ende des Zylinders angeordnete Ringraum für die äußere Ölkühlung wird im Gegensatz zu DE 33 14 543 rings umIn contrast to DE 33 14 543, the annular space for the external oil cooling arranged at the upper end of the cylinder is also all around
den Zylinder geleitet. Der dafür nötige größere Zylinderabstand wird dadurch geschaffen, daß der Kurbeltrieb für jeden Zylinder eine gesonderte Kröpfung hat und nicht, wie bei V-Motoren üblich, von einem Kurbelzapfen zwei Zylinder bedient werden.passed the cylinder. The larger cylinder spacing required for this is created by the crank mechanism for each cylinder has a separate offset and not, as is usual with V-engines, two cylinders are served by one crank pin.
Bezüglich der Reduzierung von Aufheizung und Kühlung bedient sich die vorliegende Anmeldung der in der Schrift DE 33 14 543 gezeigten Kolben und Brennverfahren. Um die Wärmeemission aber noch zu verkleinern, sind die Zylinder und der halbe Zylinderkopf dadurch von der Wärmeabstrahlung nach außen ferngehalten, daß die Motorenwände und der Motorendeckel mit doppelter Wand und mit einer dazwischenliegenden Isolierschicht ausgeführt sind .With regard to the reduction of heating and cooling, the present application makes use of DE 33 14 543 Pistons shown and combustion process. In order to reduce the heat emission even further, the cylinders and half the cylinder head are thereby kept away from the heat radiation to the outside, that the motor walls and the motor cover are designed with a double wall and an insulating layer in between are .
Was in diesem Falle der Reduzierung von Wärmeemission dient, ergibt auch eine Verminderung der Schallemission, die für den Dieselmotor immer dringlicher wird.What serves to reduce heat emission in this case also results in a reduction in sound emission, which is important for the Diesel engine is becoming more and more urgent.
Die Reduzierung der Schadstoffemission, z. B. CH, ergibt sich bei der vorgesehenen Rundumkühlung des Zylinders dadurch, daß der Kolben dadurch viel gasdichter ausgeführt werden kann. Er kann auch bereits oberhalb der Kolbenringe völlig dicht an den Zylinder angelegt werden. In diesem Punkt waren alle bisherigen Kühlungsarten deshalb mangelhaft, weil die Kolben der thermischen Unrundheit des Zylinders nicht angepaßt werden können. In den Dichtspalten entstehen Schadstoffe.The reduction in pollutant emissions, e.g. B. CH, results with the provided all-round cooling of the cylinder in that the piston can be made much more gas-tight. He can also be placed completely close to the cylinder above the piston rings. All previous ones were on this point Types of cooling are inadequate because the pistons cannot be adapted to the thermal out-of-roundness of the cylinder. In pollutants arise in the sealing gaps.
Für die anteilmäßige größte Emission, den CO2-Ausstoß, wird es künftig bedeutsam sein, daß die große Wärmedichtheit des Brennverfahrens und der Brennraumteile mit einer optimalen Gasdichtheit von Kolben und Zylinder gepaart ist. Nur so können statt Erdölprodukten Pflanzenöle als Motorentreibstoff eingesetzt werden.For the proportionate largest emission, the CO 2 emissions, it will be important in the future that the high level of heat tightness of the combustion process and the combustion chamber parts is paired with an optimal gas tightness of the piston and cylinder. This is the only way to use vegetable oils as engine fuel instead of petroleum products.

Das Spritzöl (5) wird von Leitschaufeln (6) in Richtung des Kolbenoberteils (7) gesteuert und von dort wieder zum Kolbenunterteil (8) zurückbefördert. Durch eine zweite Bohrung (9) fließt Kühlöl in den Ringraum (10), der sich in den Zylinderkopf (11) hinein fortsetzt. Vom Ringraum (10) fließt das Kühlöl durch eine Bohrung (12, 13) in den Ventilsteuerungsraum (14), von wo aus es in den gemeinsamen Ölraum (15) umgelenkt wird und die Zylinder (4) von außen her mit Spritzöl kühlt.(4) Inject in the plane of movement of the connecting rod. The spray oil (5) is from guide vanes (6) in the direction of the piston upper part (7) controlled and from there returned to the piston lower part (8). By a second bore (9), cooling oil flows into the annular space (10), which continues into the cylinder head (11). The cooling oil flows from the annular space (10) through a bore (12, 13) into the valve control space (14), from where it emerges it is deflected into the common oil chamber (15) and the cylinder (4) is cooled from the outside with spray oil.
Über diesen gemeinsamen Ölraum (15) beider Zylinderreihen ist ein gemeinsamer Deckel (16) gespannt, der die beiden Ventilsteuerungsräume (14) abschließt. Nur der außerhalb des Ventilsteuerungsraumes (14) befindliehe Teil des Zylinderkopfes (11) ist nicht mit Öl benetzt. Durch diesen Teil des Zylinderkopfes (11) führen die Kanäle für Einlaß (17) und Auslaß (18). Der Rücklauf des äußeren Kühlöls führt zwischen den freistehenden Zylindern (4) hindurch und wird durch die schall- und wärmeisolierte Außenwand (19) begrenzt.Via this common oil space (15) of both rows of cylinders a common cover (16) is clamped, which closes the two valve control chambers (14). Just which is located outside of the valve control space (14) Part of the cylinder head (11) is not wetted with oil. Through this part of the cylinder head (11) lead the channels for inlet (17) and outlet (18). The return of the external cooling oil leads between the freestanding ones Cylinders (4) and is limited by the sound and heat insulated outer wall (19).
Die Zylinder (4) sind völlig freistehend angeordnet, so daß der Ringkanal (10) rund um den ganzen Zylinder läuft. Auch an der Innenseite des Zylinders wird eine Ölkühlung am ganzen Zylinderumfang erreicht. Zu diesem Zweck hat das Kolbenunterteil (8) an seiner InnenseiteThe cylinders (4) are arranged completely free-standing, so that the annular channel (10) around the entire cylinder runs. Oil cooling is also achieved on the inside of the cylinder over the entire circumference of the cylinder. To this The purpose of the lower piston part (8) is on its inside
die Leitschaufeln (6), die in Richtung des Kolbenbolzens (20) verlaufen, und an seiner Außenseite Leitflächen (31) (Fig. 2), die guer zum Kolbenbolzen (20) stehen. So erreicht das Kühlöl den ganzen Zylinderum-the guide vanes (6) pointing towards the piston pin (20) run, and on its outside guide surfaces (31) (Fig. 2), which cross to the piston pin (20) stand. In this way, the cooling oil reaches the entire cylinder area.
fang und etwa 80 % der Zylinderlänge der inneren Zylinderfläche. Nicht erreicht wird vom inneren Kühlöl die vom Kolbendichtmantel (22) abgedeckte Zylinderfläche, weshalb der Dichtmantel an seiner inneren Fläche mit Spritzöl (5) gekühlt wird. Der Ringkanal (10) ist etwafang and about 80 % of the cylinder length of the inner cylinder surface. The cylinder surface covered by the piston sealing jacket (22) is not reached by the inner cooling oil, which is why the sealing jacket is cooled on its inner surface with spray oil (5). The ring channel (10) is about
so tief eingestochen, wie die Länge des Dichtmantels beträgt, so daß auch an diesem wichtigen oberen Zylinderteil beiderseits gute Ölkühlung garantiert ist.Pierced as deep as the length of the sealing jacket, so that also on this important upper part of the cylinder Good oil cooling is guaranteed on both sides.
Die geräuschemittierenden Teile, wie Nockenwelle (23), Ventiltrieb (24), Einspritzpumpe (25) und Düse (26), sind ebenfalls im gemeinsamen schall- und wärmeabgedichteten Ölraum (15) untergebracht. Die höhere Betriebstemperatur für die Einspritzelemente ist beabsichtigt, da sie für den Brennstoff Pflanzenöl erforderlich ist.The noise-emitting parts, such as the camshaft (23), valve train (24), injection pump (25) and nozzle (26), are also housed in the common sound- and heat-sealed oil chamber (15). The higher operating temperature for the injectors is by design as they require vegetable oil for the fuel is.
Im Kolbenbrennraum (27) ist ein Brennverfahren vorgesehen, bei dem um die heiße Brennzone (28) die Überschußluft (29) rotiert, was einen guten Schutz gegen hohe Temperaturen im Kolbenoberteil (7) ergibt.A combustion process is provided in the piston combustion chamber (27), in which the excess air (29) rotates around the hot combustion zone (28), which is a good protection against results in high temperatures in the upper piston part (7).

Das Öl wird hier kurzzeitig durch den unteren Öldichtrand (33) festgehalten, um eine intensivere Zylinderwandkühlung in dieser Ebene zu erreichen. Es fließt dann durch die Bohrungen (34) in den unteren Teil des Zylinders (4) ab. Die Pfeile (35) zeigen das an den Leitflächen (6) hochgespritzte Öl, das vom Kolbenoberteil zurückgelenkt wird.(31), which catch the spray oil (5) (Fig. 1) thrown back from the piston upper part (7) (Fig. 1) and into the Redirect the hole for the piston pin (32). The oil is here briefly through the lower oil sealing edge (33) held in order to achieve a more intensive cylinder wall cooling in this plane. It then flows through that Bores (34) in the lower part of the cylinder (4). The arrows (35) show that on the guide surfaces (6) splashed oil that is deflected back by the piston top.
