Definitions

  • the invention relates to a device for automatic lubricant level control and optionally for lubricant replenishment in internal combustion engines with an oil pan of the internal combustion engine associated fill level monitoring, with a storage tank for lubricant and with a pumping device for level monitoring dependent introduction of lubricant in the oil pan from the storage tank.
  • the invention is therefore based on the object to provide a device for automatic lubricant level control and optionally for lubricant replenishment for internal combustion engines, which allows the most accurate automatic detection of the lubricant level with simple means and in particular level fluctuations by driving dynamics changes as inclination changes, compensates.
  • the invention solves this problem by the fact that the oil pan of the internal combustion engine, an inclination sensor and a level sensor are assigned and that a control unit detects both the lubricant level and the inclination of the oil pan around at least one axis and computes the influence of the lubricant level by the oil pan inclination.
  • the present invention uses a level sensor which outputs an analog or digital output signal to the oil level present at the measuring location, ie not only detects a threshold value being undershot, but also allows an exact inference to the level at the time of measurement.
  • the engine oil pan is associated with a tilt sensor, for example, attached to the oil pan, which determines bank angles either in one or two levels.
  • two tilt sensors can determine both the pitch and roll.
  • an acceleration sensor may additionally be provided, which also takes into account changes in the driving dynamics caused by acceleration and braking.
  • the device according to the invention allows a direct check of a completed oil refilling via the measured increase in the oil level after refilling and thus indirectly also a review of the overall system.
  • the exact lubricant requirement of the internal combustion engine can be continuously calculated by determining the deviation of the actual value of the lubricant level from the optimum lubricant level. A calculation of the lubricant consumption per operating hour as well as the calculation of trend curves with limit values, which indicate a overdue overhaul of the engine, is thus easily possible.
  • a pumping device in particular motor pump unit, which selectively conveys the lubricant from the storage tank into the dosing tank or from the dosing tank into the oil sump.
  • This can be realized by a corresponding hydraulic circuit or by a reversal of the conveying direction of the pump with provision of corresponding check valves in the respective lines.
  • the system according to the invention is not only suitable for monitoring an internal combustion engine, but is also recommended in particular by lubricant level control of at least two internal combustion engines, the oil pan of each internal combustion engine, a tilt sensor and a level sensor are assigned and the introduction of lubricant into the oil pan via a hydraulic circuit, which releases the lubricant supply in each case to an internal combustion engine to be supplied. If the internal combustion engines are arranged together on a rigid frame, only one inclination sensor can be sufficient and fulfill the purpose.
  • the control unit evaluates inclinations and levels of each engine for itself and can provide the respective internal combustion engines with the desired amount of lubricant via the pumping device, including the hydraulic circuit is provided which releases the respective supply line or the respective supply lines.
  • a device for automatic lubricant level control and optionally for lubricant filling of internal combustion engines 1 includes, inter alia, one of the oil pan 2 of the internal combustion engine 1 associated level monitoring, a level sensor 3, a storage tank 4 for lubricant 5 with a pumping device 6 for level monitoring dependent introduction of lubricant 5 in the oil pan 2 from the Storage tank 4.
  • the oil pan 2 of the internal combustion engine 1 each at least one tilt sensor 7 and a level sensor 3 are assigned.
  • a control unit 8 which detects both the lubricant level and the inclination of the oil pan 2 by at least one axis by evaluating the data of inclination sensor 7 and level sensor 3 and computationally compensates for the influence of the lubricant level by the oil pan inclination.
  • a metering tank 10 equipped with a level sensor 9 or a level sensor is provided for exact dimensioning of the quantity of lubricant required for refilling to the nominal level in the oil pan 2.
  • the pumping device 6 conveys the lubricant with a pump 11 from the storage tank 4 into the dosing tank 10.
  • the pump 11 conveys the lubricant from the dosing tank 10 into the oil sump 2.
  • check valves 12 are arranged in the respective lines to avoid a complicated control. However, the conveying direction of the pump 11 must be reversible.
  • the lubricant level control is provided for two internal combustion engines 1. However, any number of internal combustion engines can be monitored and filled.
  • Each oil pan 2 of each internal combustion engine 1 is associated with a tilt sensor 7 and a level sensor 3.
  • the hydraulic circuit 13 is equipped with corresponding switching valves.
  • the control unit 8 is assigned a GPS sensor 14 and the measurement data together with the GPS data can be transmitted via a modem 15 to a central processing unit.
  • the control unit sends error messages, such as an increase in the fill level in the sump, above-average oil consumption, sudden oil loss or error of the device itself, in particular when exceeding predetermined limits, messages to a monitoring.
  • Fig. 2 schematically shows the oil pan 2 with the level sensor 3 and the inclinometer 7.
  • Fig. 2 an analog level sensor 3, which is constructed on the basis of communicating vessels. But of course, level sensors on the basis of hydrostatic pressure, ultrasonic or direct level measurement resistive systems in the oil pan or the like. Possible.
  • the connecting line 16 to the communicating measuring system, the level sensor 3 at the coordinates x L and y L on the oil pan bottom.
  • the oil level measured at this point corresponds to z m .
  • the oil pan is located in a longitudinal inclination ⁇ . If the oil pan is tilted by an inclination angle ⁇ to the vertical, then the oil level z m would be displayed.
  • the measured value z m must be corrected by d z to the corrected measured value z ⁇ .
  • the oil pan has a length I and a width b.
