zum automatischen Nachfüllen von Öl oder Schmiermittel nach der Gattung des
Patentanspruches 1.The invention relates to an internal combustion engine with an oil pan and a device
for the automatic refilling of oil or lubricant according to the type of
Ein solches Nachfüllsystem ist beispielsweise aus dem Dokument US 4 989 560 bekannt. Demnach kann das Schmierölsystem einer Brennkraftmaschine durch einen Vorratstank nachgefüllt werden, so dass immer die optimale Menge an Schmieröl im Kreislauf vorhanden ist. Ein Trockenlaufen der Maschine kann ohne Wartungsaufwand auf diese Weise verhindert werden. Allerdings muß die Funktion des Nachfüllsystems kontrolliert werden. Hier werden verschiedene Funktionen, insbesondere auch die Starterbatterie überprüft. Wenn diese nicht zuverlässig arbeitet, wird der Nachfüllvorgang nicht in Gang gesetzt, um die Förderung falscher Ölmengen zu vermeiden.Such a refill system is known for example from document US 4,989,560. Accordingly, the lubricating oil system of an internal combustion engine can be supplied by a storage tank be refilled so that the optimum amount of lubricating oil is always available in the circuit is. This prevents the machine from running dry without maintenance become. However, the function of the refill system must be checked. Be here various functions, in particular the starter battery checked. If not works reliably, the refill process is not started to promote to avoid wrong amounts of oil.
Hierdurch wird ein Überfüllen des Öls der Brennkraftmaschine verhindert. Wird jedoch über längere Zeit ein Fehler der Batterie ausgegeben, kann das Öl über einen längeren Zeitraum nicht nachgefüllt werden, so dass ein Trockenlaufen der Brennkraftmaschine, erfolgen kann. Damit besteht ein Restrisiko für die Funktion der Brennkraftmaschine.This prevents overfilling of the oil in the internal combustion engine. However, will If the battery has been faulty for a long time, the oil may run for a long time not be refilled so that the internal combustion engine can run dry. There is therefore a residual risk for the function of the internal combustion engine.
Aufgabe der Erfindung ist es daher, ein Nachfüllsystem für den Schmierölkreislauf einer Brennkraftmaschine zu schaffen, welches unabhängig vom Zustand der Batterie als Antriebsquelle zuverlässig betreibbar ist.The object of the invention is therefore a refill system for the lubricating oil circuit To create internal combustion engine, which regardless of the state of the battery as Drive source can be operated reliably.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale von Anspruch 1 gelöst.According to the invention, this object is achieved by the features of
Dadurch wird garantiert, daß in der Brennkraftmaschine ständig eine ausreichende Menge Öl für den sicheren Betrieb derselben vorhanden ist, ohne dabei einen Druckabfall im Ölkreislauf zu riskieren und damit letztlich den Ausfall der Maschine. This guarantees that there is always a sufficient amount of oil in the internal combustion engine for the safe operation of the same is present, without a pressure drop in the oil circuit to risk and ultimately the failure of the machine.
Vorteilhafterweise weist die Steuer- bzw. Regeleinheit wenigstens ein Regelglied auf, daß die Fördermenge der Pumpe als Funktion der elektrischen Bordspannung der Brennkraftmaschine darstellt Da die Förderleistung der Pumpe, naheliegenderweise einer elektrisch betriebenen, von der tatsächlich anliegenden Betriebsspannung abhängt, wird auch dieser Wert zu einem Einflußfaktor bezüglich der effektiven Fördermenge. Üblicherweise differieren die Bordspannungswerte um bis zu 8 Volt Derartige Toleranzen rühren zu Förderdifferenzen von bis zu 40% pro Zeiteinheit. Aus diesem Grund muß die Steuer- bzw. Regeleinheit eine Spannungskompensation mittels Regelglied in der Form vornehmen, daß bei höheren Betriebsspannungen kürzere Pumpzeiten erfolgen, wohingegen bei niedrigeren Spannungen die Pumpzeit entsprechend verlängert wird. Für die Messung des Ölniveaus bzw. die Nachfüllung von Schmiermittel sind sowohl der Stillstand des Fahrzeugs, in dem die Brennkraftmaschien Dienst tut als auch der eigentliche Betriebszustand als Alternativen denkbar. The control or regulating unit advantageously has at least one regulating element that the Flow rate of the pump as a function of the electrical on-board voltage of the internal combustion engine represents since the delivery capacity of the pump, obviously an electrically operated, depends on the actual operating voltage, this value also becomes one Factor influencing the effective delivery rate. Usually they differ On-board voltage values of up to 8 volts. Such tolerances result in delivery differences of up to 40% per time unit. For this reason, the control unit must be a Carry out voltage compensation using a control element in the form that higher Operating voltages result in shorter pumping times, whereas lower voltages the pumping time is extended accordingly. For measuring the oil level or the Refilling lubricants are both the standstill of the vehicle in which the Internal combustion engine service does as well the actual operating state as alternatives conceivable.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor,daß die Brennkraftmaschine einen das minimale Ölniveau der Brennkraftmaschine anzeigenden Sensor aufweist. Mittels diesem Sensor kann ohne einen Druckabfall die Versorgung mit Schmiermittel garantiert werden.An advantageous development of the invention provides that the internal combustion engine one has minimum oil level of the engine indicating sensor. By means of this The sensor can be guaranteed the supply of lubricant without a drop in pressure.
Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Brennkraftmaschine einen Sensor aufweist, der das maximal zulässige Ölniveau der Brennkraftmaschine anzeigt. Dieser Sensor schützt die Brennkraftmaschine vor einer übergebührlichen Beaufschlagung mit Schmiermittel, was zur Zerstörung von Dichtungen im Bereich des Schmiermittelkreislaufes führen könnte.Another advantageous development of the invention provides that the internal combustion engine has a sensor that displays the maximum permissible oil level of the internal combustion engine. This sensor also protects the internal combustion engine against excessive loading Lubricant, which leads to the destruction of seals in the area of the lubricant circuit could lead.

Auf diese Weise kann ein Leerlaufen des Vorratsbehälters vermieden werden, die weitere Zuverlässigkeit des Systems wird dadurch garantiert.Another advantageous development provides that the storage container has at least one oil level sensor. In this way, an idling of the Storage container are avoided, the further reliability of the system is thereby guaranteed.
Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, daß sie wenigstens einen Temperatursensor aufweist. Da die Eigenschaften von Schmiermitteln, insbesondere von Motorenöl temperaturabhängig sind, ist es von gewisser Bedeutung, daß die Steuer- bzw. Regeleinrichtung auf den jeweiligen Temperaturzustand zugreifen kann.Another advantageous development of the invention provides that it has at least one Has temperature sensor. Because the properties of lubricants, especially of Engine oil are temperature dependent, it is of some importance that the control or Control device can access the respective temperature state.
Vorteilhafterweise sind die Ölniveausensoren als PTC-Sensoren und die Temperatursensoren als NTC-Sensoren ausgeführt.The oil level sensors are advantageously PTC sensors and the temperature sensors designed as NTC sensors.
Eine vorteilhafte Weiterbildung sieht vor, daß die Steuer- bzw. Regeleinheit wenigstens ein Regelglied aufweist, das die Fördermenge der Pumpe als Funktion der Zeit darstellt. Da die Leitungsquerschnitte des Schmiermittelkreislaufs in der Regel konstant sind, ist die Zeit ein wesentlicher Parameter für das zu fördernde Schmiermittelvolumen, mittels diesem die über die Pumpe tatsächlich zur Verfügung zu stellende Menge Öl beeinflussbar istAn advantageous further development provides that the control or regulating unit has at least one Has control element, which represents the delivery rate of the pump as a function of time. Since the Line cross sections of the lubricant circuit are usually constant, the time is on essential parameter for the volume of lubricant to be conveyed, by means of which the the amount of oil that can actually be made available can be influenced
In einer anderen vorteilhaften Weiterbildung ist vorgesehen, daß die Steuer- bzw. Regeleinheit wenigstens ein Regelglied aufweist, daß die Fördermenge der Pumpe als Funktion der Temperatur, insbesondere der Öltemperatur darstellt. Durch die sich temperaturabhängig verändernden Strömungseigenschaften des Motoröls wird dessen Temperatur zu einem weiteren wesentlichen Parameter, über den die zu fördernde Ölmenge beeinflussbar ist. Der üblicherweise auftretende Temperaturbereich liegt zwischen Werten von - 40 Grad Celsius bis hin zu + 80 Grad Celsius und mehr. Je kälter das Öl ist, umso weniger Öl läßt sich pro Zeiteinheit über die Pumpe fördern. Das kann soweit führen, daß im kalten Zustand des Öls Pumpzeiten von bis zu 12 Minuten erreicht werden, wobei im wärmeren Zustand schon eine Minute zur Förderung der gleichen Menge Öls ausreichend sein kann. Deshalb erfolgt mittels der Steuer- bzw. Regeleinheit eine Temperaturkompensation. In extremen Betriebszuständen, beispielsweise bei großer Kälte kann der Fall eintreten, daß die Pumpe überlastet würde, in diesem Fall sorgt eine Überlastsicherung vor Schäden im Bereich der Pumpe.Another advantageous development provides that the control or Control unit has at least one control element that the delivery rate of the pump as Function of temperature, especially the oil temperature. By yourself The temperature-dependent changing flow properties of the engine oil becomes its Temperature to another essential parameter through which the amount of oil to be pumped can be influenced. The usually occurring temperature range lies between values of - 40 degrees Celsius up to + 80 degrees Celsius and more. The colder the oil, the less Oil can be pumped per unit of time. This can go so far that in the cold Condition of the oil pumping times of up to 12 minutes can be achieved, being warmer Condition a minute to pump the same amount of oil may be sufficient. Therefore, temperature compensation takes place by means of the control unit. In extreme operating conditions, for example in extreme cold, the case may occur that the Pump would be overloaded, in this case an overload protection device ensures damage in the area the pump.
