Definitions

  • the invention relates to a coolant circuit for an internal combustion engine having a coolant pump, at least one coolant line, a radiator and a coolant cavity in the internal combustion engine, wherein the coolant pump, the coolant line, the radiator and the coolant cavity are filled with a coolant.
  • JP S57 171019 A a system for controlling cooling characteristics for an internal combustion engine, which monitors a concentration of a coolant solution in a water cooling and controls the operation of a water pump depending on the concentration of the coolant solution.
  • a similar coolant circuit is off JP H10 259730 known.
  • An object on which the invention is based is to provide a coolant circuit which permanently protects the internal combustion engine from damage caused by the improper use of coolant.
  • the invention is characterized in that at least one sensor for monitoring the coolant concentration is permanently and permanently arranged in and / or on the coolant circuit.
  • This has the advantage that too low a concentration of the antifreeze in the coolant can be reliably detected outside of the workshop stays of the vehicle. Too high a concentration of antifreeze can be detected with the coolant circuit according to the invention.
  • the described coolant circuit comprises an ambient temperature sensor and an electronic control unit, which is connected to the ambient temperature sensor and which is designed to determine a minimum operating temperature of the coolant as a function of the measuring signals of the sensor and to compare these with the measuring signals of the ambient temperature sensor. Such a comparison of the minimum operating temperature of the coolant and the ambient temperature can in particular also take place after the internal combustion engine has stopped.
  • the sensor for monitoring the coolant concentration is an ultrasonic sensor.
  • Ultrasonic sensors are long-lasting and cost-effective components with which the concentration of antifreeze in the coolant can be reliably detected.
  • the coolant circuit additionally has an expansion vessel.
  • the sensor for monitoring the coolant concentration may be arranged in or on the expansion vessel.
  • the expansion tank is in usually a readily accessible component, which allows the inclusion of a sensor for monitoring the coolant concentration easily.
  • the sensor for monitoring the coolant concentration is arranged in or on the coolant cavity.
  • the coolant cavity is located in the internal combustion engine itself, with which the sensor for monitoring the coolant concentration can protect the internal combustion engine against freezing in a particularly effective manner.
  • the sensor for monitoring the coolant concentration is arranged in or on the coolant pump and / or arranged in or on the coolant line, an effective monitoring of the proportion of antifreeze in the coolant can also take place and thus the coolant concentration can be determined reliably. This also applies if the sensor for monitoring the coolant concentration is arranged in or on the radiator.
  • the sensor transmits its measurement results to the electronic control unit for monitoring the coolant concentration. Due to the fact that the electronic control unit is additionally connected to an ambient temperature sensor, it can be determined with certainty whether the ambient temperature has fallen so far that there is a risk for the cooling circuit and / or the internal combustion engine.
  • the electronic control unit based on the measurement results of the sensor for monitoring the coolant concentration determines a minimum operating temperature for the coolant and compares this minimum operating temperature for the coolant with the measurement result of the ambient temperature sensor. As a result, a freezing of the coolant in the coolant circuit can be reliably detected.
  • the electronic control unit generates an electronic warning signal when the measurement result of the ambient temperature sensor falls below the minimum operating temperature of the coolant.
  • This electronic warning signal may, for example, be displayed to the vehicle driver in the form of an error message and / or be used so that the internal combustion engine can not be started or shut down.
  • the monitoring of the coolant concentration and the determination of the minimum operating temperature of the coolant, as well as the comparison with the measurement result of the ambient temperature sensor also take place after the engine has come to a standstill, thus the most probable case, namely the freezing of the parked internal combustion engine, can be reliably detected.
  • Fig. 1 shows an internal combustion engine 1 with four cylinders and a arranged on the internal combustion engine 1 exhaust manifold 15.
  • a coolant circuit 2 is formed on the internal combustion engine 1.
  • the coolant circuit 2 for the internal combustion engine comprises a coolant pump 3, at least one coolant line 4, a cooler 7 and cooling cavities 13 in the internal combustion engine 1.
  • the coolant 5 can absorb and remove the heat from the hot internal combustion engine 1.
  • the hot coolant is transported from the coolant pump 3 through the coolant line 4 to the cooler 7, where the coolant 5 is usually cooled by passing cold air and then again the internal combustion engine 1 is supplied.
  • the coolant 5 of an internal combustion engine 1 in motor vehicles usually consists of water, to which some substances that reduce corrosion are added.
  • This water has the property of freezing at temperatures of less than 0 ° C, which can lead to serious damage to the internal combustion engine 1 or the coolant circuit 2. Therefore, the aqueous coolant 5 is usually added substances that lower the freezing point of the solution well below 0 ° C. In the course of a vehicle life, however, it may happen that the concentration of the substances that reduce the freezing point of the coolant 5, too low, whereby a freezing of the internal combustion engine 1 or the coolant circuit 2 is possible. To prevent this, a sensor 8 for monitoring the coolant concentration is permanently and permanently arranged in the coolant circuit 2.
  • This sensor 8 for monitoring the coolant concentration may for example be an ultrasonic sensor.
  • an expansion vessel 6 can be arranged in the coolant circuit 2. This expansion vessel 6 can compensate for the thermal expansion of the coolant 5 in the coolant circuit 2.
  • the sensor 8 for monitoring the coolant concentration may, for. B. may be arranged in or on the coolant cavity 13 of the internal combustion engine 1. In combination or as an independent solution, the sensor 8 for monitoring the coolant concentration may be arranged on or in the coolant pump 3. In addition, the sensor 8 may be arranged to monitor the coolant concentration in or on the coolant line 4 and / or in or on the cooler 7.
  • the sensor 8 for monitoring the coolant concentration transmits the detected concentration of the coolant solution 5 to an electronic control unit 9.
  • This electronic control unit 9 can determine information about the coolant concentration, the temperature below which the coolant 5 would freeze. This temperature can be compared with an outside temperature, which is transmitted from an ambient temperature sensor 14 to the electronic control unit 9. Once the electronic control unit detects that the outside temperature falls below the glass transition temperature of the coolant 5, the electronic control unit may generate a warning signal and / or electronically ensure that the supercooled and / or frozen internal combustion engine is not started.
  • Fig. 2 shows a concentration sensor 8, which is designed as an ultrasonic sensor.
  • the sensor element 17 is excited by a frequency generator 10, which is integrated in the electronic control unit 9 to vibrate.
  • the sensor element 17 can also be excited to oscillate by an electrical circuit 9, wherein the electrical circuit 9 is a component of the concentration sensor 8 itself.
  • These vibrations have frequencies in the ultrasonic range, whereby an ultrasonic wave 11 is emitted and passes through the coolant 5 to a reflector 12. At the reflector 12, the ultrasonic wave 11 is reflected and thrown back to the sensor element 17.
  • the sensor element 17 now acts as a receiver for the ultrasonic wave 11, wherein the transit time of the ultrasonic wave 11 from the sensor element 17 via the reflector 12 back to the sensor element 17 is characteristic of the concentration of the freezing point lowering additives in the coolant.
  • the sensor 8 shown here for monitoring the coolant concentration can deliver a corresponding signal to the concentration of the coolant to the electronic control unit 9, whereby the electronic control unit 9 can then calculate the temperature from which the coolant 5 would freeze.
  • the presented here coolant circuit 2 for an internal combustion engine 1 with at least one sensor 8 for monitoring the coolant concentration can help to avoid expensive damage to the internal combustion engine 1 and thus conserve resources.
