Abstract
Description
Die vorliegende Erfindung betrifft ein Schmiersystem für Verbrennungsmotoren gemäß dem Oberbegriff des Patentanspruches 1.The present invention relates to a lubrication system for Internal combustion engines according to the generic term of claim 1.
Ein derartiges Schmiersystem ist

Aufgabe der Erfindung ist es, ein Schmiersystem für Verbrennungsmotoren zu schaffen, das insbesondere in der Startphase des Verbrennungsmotors eine verbesserte Schmierung der einzelnen Motorkomponenten ermöglicht.The object of the invention is a Lubrication system for To create internal combustion engines, especially in the starting phase the internal combustion engine improved lubrication of the individual engine components allows.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This task is due to the characteristics of claim 1 solved. Advantageous refinements and developments of the invention are the subclaims refer to.
Das Grundprinzip der Erfindung besteht darin, ein unter Druck stehendes, mit Öl gefülltes Motorölreservoir über ein absperrbares Ventil an den Motorölbaum anzuschließen. Beim Start des Motors wird das Ventil geöffnet. Das unter Druck stehende Motoröl aus dem Motorölreservoir strömt dann in den Motorölbaum. Im Motorölbaum baut sich somit praktisch ohne bzw. mit einer nur sehr geringen Zeitverzögerung ein hinreichend hoher Öldruck auf, der eine zuverlässige Schmierung der einzelnen Schmierstellen im Motor sicherstellt. Das im Motorölreservoir unter Druck gespeicherte Öl dient also zur "Überbrückung" der Zeitspanne, welche die Motorölpumpe in der Startphase des Verbrennungsmotors benötigt, um einen hinreichenden Öldruck im Motorölbaum aufzubauen.The basic principle of the invention is inside, a pressurized, oil-filled engine oil reservoir via a lockable valve to the engine oil tree to join. The valve opens when the engine starts. The pressurized engine oil from the Engine oil reservoir flows then in the engine oil tree. In the engine oil tree builds practically without or with very little Time Delay a sufficiently high oil pressure on who is a reliable Lubrication of the individual lubrication points in the engine ensures. The in the engine oil reservoir oil stored under pressure serves to "bridge" the time span, which is the engine oil pump in the start-up phase of the internal combustion engine is required to maintain an adequate oil pressure in the Build engine oil tree.
Wenn die Ölpumpe den Öldruck aufgebaut hat, dann wird bei weiterhin geöffnetem Ventil Motoröl zurück in das Motorölreservoir gepumpt (Füllphase). Im Motorölreservoir baut sich somit allmählich wieder ein Öldruck auf, der in der nächstfolgenden Startphase zur "Vorschmierung" verwendet wird.If the oil pump has built up the oil pressure, then is opened with the Engine oil valve back into the engine oil reservoir pumped (filling phase). In the engine oil reservoir thus gradually rebuilds an oil pressure on, in the next starting phase is used for "pre-lubrication".
Das Ventil zwischen der Motorölpumpe bzw. dem Motorölbaum und dem Motorölreservoir wird geschlossen, sobald eine hinreichend große Ölmenge zurück in das Motorölreservoir gepumpt worden ist bzw. sobald im Motorölreservoir ein vorgegebener Öldruck bzw. ein vorgegebener Ölfüllstand erreicht ist.The valve between the engine oil pump or the Engine oil tree and the engine oil reservoir is closed as soon as a sufficiently large amount of oil is returned to the engine oil reservoir has been pumped or as soon as a specified oil pressure or a predetermined oil level is reached.
Nach einer Weiterbildung der Erfindung weist das Motorölreservoir ganz allgemein gesprochen, eine "Ölspeicherkomponente" und eine "Druckspeicherkomponente" auf. Die Druckspeicherkomponente speichert Druckenergie. Sie stellt sicher, dass unmittelbar beim Start des Motors ein hinreichend hoher Öldruck zur Verfügung steht.According to a development of the invention the engine oil reservoir in general terms, an "oil storage component" and a "pressure storage component". The accumulator component stores printing energy. It ensures that immediately at Starting the engine a sufficiently high oil pressure is available.
Das Motorölreservoir kann beispielsweise ein Behälter sein, der teilweise mit einem kompressiblen Fluid im übrigen mit Motoröl gefüllt ist. Wenn Motoröl in das Motorölreservoir gepumpt wird, dann wir das Fluid komprimiert.The engine oil reservoir can be, for example container be the one with a compressible fluid in the rest Engine oil filled is. If engine oil into the engine oil reservoir is pumped, then the fluid is compressed.
Alternativ dazu kann das Motorölreservoir auch ähnlich einem Ausgleichsbehälter aufgebaut sein, wie er bei Heizungsanlagen verwendet wird. Der Ausgleichsbehälter weist eine elastische Membran auf, die ein mit Öl befülltes Volumen von einem mit einem kompressiblen Medium, z.B. Luft, befüllten Teilvolumen trennt.Alternatively, the engine oil reservoir may be similar to one surge tank be constructed as it is used in heating systems. The expansion tank points an elastic membrane that has a volume filled with oil from one a compressible medium, e.g. Air separates the filled partial volume.
Alternativ dazu kann das Motorölreservoir auch zwei durch einen verschieblichen Kolben voneinander getrennte Teilvolumina aufweisen, wobei sich in dem einen Teilvolumen Öl und in dem anderen Teilvolumen ein kompressibles Medium befindet oder wobei der Kolben durch eine Feder vorgespannt ist.Alternatively, the engine oil reservoir can also two partial volumes separated from each other by a movable piston have oil in one part volume and in the other part volume there is a compressible medium or the piston is covered by a Spring is biased.
