Definitions
- 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 Claim 1.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the oil level sensors are advantageously PTC sensors and the temperature sensors designed as NTC sensors.
- 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
- 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.
- 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.
- 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.
- the internal combustion engine (1) consists of an engine block with an oil pan (2) in which the oil required for operation is stored.
- An oil level sensor (3) is mounted inside the oil pan (2) and sends a signal to the electrical control unit (8) when a defined minimum level is reached.
- a storage container (5) that contains fresh oil that enters the interior through the filler opening (4).
- This reservoir is connected to the engine block or to the oil pan (2) by means of a connecting line (6).
- a pump (7) is located at one end of the connecting line (6).
- the pump (7) is designed as a gear pump so that operating conditions down to -40 degrees Celsius can be controlled and driven by an electric motor.
- In the reservoir (5) there is a PTC oil level sensor (3) which guarantees a minimum oil quantity in the reservoir (5) of three liters.
- this PTC sensor (3) transmits a signal to the electrical control device (8), which then lights up an indicator lamp (10) and prevents the pump (7) from running dry.
- an NTC temperature sensor (3) in the reservoir (5) which transmits the current temperature of the fresh oil to the electrical control device (8).
- the control unit (8) processes the signals from the various sensors (3) in such a way that when the oil level sensor (3) in the oil pan reports the minimum level, by means of the sensor information from the reservoir (5) and on the basis of the in 2 and 3 and in the functional relationships implemented in the electrical control and regulating unit (8) by means of regulating elements, a time-dependent delivery signal is transmitted to the pump (7).
- the fresh oil that is drawn in by the pump (7) via a suction pipe (9) reaches the oil pan (2) in portions per delivery cycle of 300-800 ml via the connecting line (6).

Zusätzlich existiert ein Vorratsbehälter (5), der Frischöl, welches über die Einfüllöffnung (4) ins Innere gelangt, beinhaltet. Dieser Vorratsbehälter ist mit dem Motorblock, bzw. mit der Ölwann (2) mittels einer Verbindungsleitung (6) verbunden. Am einen Ende der Verbindungsleitung (6) befindet sich eine Pumpe (7). Die Pumpe (7) wird als Zahnradpumpe ausgeführt, damit Betriebszustände bis -40 Grad Celsius beherrscht und mit einem Elektromotor angetrieben werden können. Im Vorratsbehälter (5) befindet sich ein PTC-Ölniveausensor (3), der eine Mindestölmenge im Vorratsbehälter (5) von drei Litern garantiert. Wenn die Dreilitermarke erreicht ist, übermittelt dieser PTC-Sensor (3) ein Signal an die elektrische Steuer- bzw. Regeleinrichtung (8), die daraufhin eine Anzeigelampe (10) aufleuchten läßt und ein Trockenlaufen der Pumpe (7) verhindert. Weiter befindet sich im Vorratsbehälter (5) ein NTC-Temperatursensor (3) der die aktuelle Temperatur des Frischöls an die elektrische Steuer- bzw. Regeleinrichtung (8) übermittelt. Die Steuer- bzw. Regeleinheit (8) verarbeitet die anfallenden Signale der verschiedenen Sensoren (3) derart, daß wenn der Ölniveausensor (3) in der Ölwanne das Minimalniveau meldet, mittels der Sensorinformation aus dem Vorratsbehälter (5) und den auf Basis der in den Figuren 2 und 3 dargestellten und in den in der elektrischen Steuer- und Regeleinheit (8) mittels Regelgliedern umgesetzten Funktionszusammenhängen ein zeitabhängiges Fördersignal an die Pumpe (7) übermittelt wird. Das Frischöl, das von der Pumpe (7) über ein Saugrohr (9) angesaugt wird gelangt über die Verbindungsleitung (6) in Portionen pro Förderzyklus von 300 - 800 ml in die Ölwanne (2).
