Definitions

  • the invention relates to an air-compressing, self-igniting (diesel) reciprocating internal combustion engine, preferably with direct injection of the fuel, with a cooling air blower which can be driven hydraulically, an electromagnetic directional control valve being arranged in the hydraulic feed line and depending on influencing variables of the internal combustion engine or with your connected machines can be controlled by periodic pulses by means of a measured value processing device supplied by an electrical on-board system.
  • Such a generic reciprocating internal combustion engine with a measured value processing device is known from DE-OS 29 38 706.
  • a measurement value processing device is addressed globally, which delivers changeable output signals for an electromagnetic valve.
  • the person skilled in the art finds that a number of essential questions have not been addressed, so that inventive steps and considerations start here.
  • other devices to be regulated in the reciprocating piston internal combustion engine are also to be controlled or regulated automatically. This also applies, for example, to an annealing system to improve the cold start and the cold running properties of the reciprocating piston internal combustion engine.
  • the object of the invention is therefore to provide a generic H ubkolbenbrennkraftmaschine to improve the cooling air fan and to expand and to unite further comprising control devices of other units of the reciprocating internal combustion engine having a measurement processing for the regulation, wherein this device also to be improved and extended.
  • this device also to be improved and extended.
  • a simple, problem-free operation with an automatic process should be guaranteed.
  • the object of the invention is achieved in that the reciprocating piston internal combustion engine is equipped in a manner known per se with a glow system, preferably with one glow plug per reciprocating piston unit, to which a control device for controlling the relay or relays of the glow system is assigned, that the control device and the Measured value processing device are combined to form an electronic central control device and that the central control device is controlled by a stop-drive-start operating switch.
  • a control device for controlling the relay or relays of the glow system is assigned
  • the control device and the Measured value processing device are combined to form an electronic central control device and that the central control device is controlled by a stop-drive-start operating switch.
  • the delta voltage generator has a cycle time of 2 seconds. Furthermore, it is advantageously possible to assign the measured value transmitters to the influencing variables of the internal combustion engine or the machines connected to it both to the measured value processing device for the cooling air fan and to the control device of the glow system. Component temperatures of the internal combustion engine, operating medium temperatures of the internal combustion engine and the downstream machines, for example a transmission, come into consideration as influencing variables. Furthermore, it is possible to measure ambient temperatures and thus the temperature of the air drawn in by the internal combustion engine or by the cooling air blower or to determine the temperature of the hot cooling air or the exhaust gases. Furthermore, in the case of an electronic central control device, it is advantageously possible to provide information for the operator by means of a central control lamp which conveys information from both the measured value processing device and the control device of the operator.
  • a particularly advantageous embodiment of the control device which leads to a fully automatic sequence of the glow system, is ensured by the fact that one or more electronic switches for controlling the relay or relays are provided, which switch from a rapid heating circuit to the maximum current supply of the glow system, and also from an activation of the Battery voltage on the power to supply the glow system and by switching on the battery voltage drop when starting the internal combustion engine machine can be controlled.
  • a plurality of relays may be provided for driving the glow plugs.
  • a relay is sufficient. Due to the different control of the electronic switch or switches, almost all important influencing variables can be taken into account. It is therefore advantageously possible to heat up the glow system as quickly as possible, then to supply it with the necessary power as a function of the battery voltage and to take voltage drops into account when starting the internal combustion engine. Depending on the temperature, these voltage drops can be very considerable and would lead to a reduction in the glow of the glow system.
  • the rapid heating circuit advantageously has a temperature-dependent resistor (thermistor) for determining the rapid heating time, the rapid heating time being determined automatically as a function of the outside temperature and the battery voltage.
  • the temperature characteristic of the thermistor is the annealing emperaturkennline adapted in an advantageous manner of the T.
  • the electronic central control device or the control device automatically determines the rapid heating time of the glow system depending on the respective outside temperature and the battery voltage, since the thermistor also depends on the respective outside temperatures and battery voltage reacts and therefore takes a different amount of time to reach the specified temperature or the temperature-dependent change in resistance.
  • the thermistor further ensures that even in the event of an arbitrary interruption of the rapid heating time, for example because the operator switches the operating switch off again and thus briefly interrupts the heating time of the glow system, the interrupted remaining glow time is taken into account and does not lead to incorrect rapid heating of the glow system, since the thermistor under consideration of the temperature characteristic of the G lühanalge the annealing time and the remaining Restglühenergie taken into account and shortens the re Schnellloomzeit accordingly.
  • the connection of the battery voltage to the power supply to the V ER is the annealing in combination with the delta voltage generator, thereby forming a gating controller that varies the pulse width in dependence of the battery voltage.
  • connection of the battery voltage to the power for supplying the glow system and the rapid heating circuit are switched on in the driving position of the operating switch and switched off in the starting position, the switching on of the battery voltage drop being switched on in the starting position of the operating switch and switched off in the driving position.
  • the connection of the battery voltage to the power for supplying the glow system advantageously controls the power supply of the glow system in parallel to the rapid heating circuit, so that the activation of the battery voltage is also switched on directly when the operating switch is actuated. The latter then does not come into effect because the quick heating circuit takes a while wise continuous activation of the glow system, and as long as the thermistor indicates.
  • the temperature characteristic of the thermistor is adapted to the characteristic of the glow system. This is done by special selection of the thermistor. Depending on whether the thermistor is arranged in the housing of the central control unit or not, the characteristic curve changes, since the environment heats up more or less quickly or has a different temperature. Following this, ie when the rapid heating circuit is switched off, the activation of the battery voltage takes over the control, so that following a continuous power supply, a pulse control is used which ensures a constant temperature of the glow system. As soon as the rapid heating circuit has switched off, the internal combustion engine is prepared so far that starting can take place, which is indicated by the extinguishing of the control lamp described below.
  • the connection of the battery voltage and the rapid heating circuit are switched off and the connection of the battery voltage drop is switched on.
  • this controls the power supply to the glow system which in turn ensures the desired glow of the glow system, taking into account the factors already mentioned above. It should be pointed out that depending on the operating conditions of the internal combustion engine, for example in altogether warmer countries or climatic zones, the activation of the battery voltage drop can be completely dispensed with, but then the activation of the battery voltage to the power of the glow system supply can also be switched on in the starting position, not have to.
  • a further electronic switch for controlling the relay or relays is provided, which is controlled by a limit temperature circuit that can be controlled by sensors of the influencing variables of the internal combustion engine. Since the connection of the battery voltage and the rapid heating circuit in the driving position of the operating switch are continuously switched on, the glow system continues to be operated even after the internal combustion engine has started and is regulated to the desired temperature by the connection of the battery voltage in conjunction with the delta voltage generator. It is thereby achieved that the internal combustion engine reaches a more favorable warm-up phase after the start, as a result of which the undesirable “white smoke in direct-injection internal combustion engines” is eliminated. This also results in improved exhaust gas values. If the sensors of the influencing variables, for example the component temperatures of the internal combustion engine, reach a predetermined temperature, the power supply to the relay or the glow system is interrupted by the further electronic switch.
  • the transmitter of the influencing variables during operation of the internal combustion engine of measurement processing that governs the control of the cooling fan are associated with the transducers is a circuit for setting the A connected rbeits.
  • the circuits for setting the A form rbeits in conjunction with the delta voltage generator pulses applied to an electronic switch of the electromagnetic directional control valve control, wherein the pulse width in dependence of the temperatures T em the transmitter varies.
  • the pulse width variation is draulikillonkeit y-a pulsed supply of the hydraulic drive of the cooling air blower with H, thereby, a corresponding control of the cooling air blower.
  • the hydrodynamic coupling in conjunction with a conventional hydrodynamic coupling in the drive of the cooling air blower, this leads to a variable speed of the cooling air blower, with only very slight fluctuations, since the hydrodynamic coupling usually has a constant outflow and the electromagnetic directional valve is arranged in the hydraulic feed line, as a result of which the oil level in the hydrodynamic Clutch varies.
  • the pulse width can vary from "zero" to almost “constant".
  • the transducers of the influencing variables are advantageously assigned a monitoring circuit which, in the event of a break in the lines to the transducers, actuates an electrical switch in order to light up the indicator lamp, as a result of which the operator is made aware of the error.
  • a flashing circuit of the control lamp is generated in connection with the monitoring circuit, so that this gives a special indication by means of the control lamp of the break in the lines to the sensors.
  • the output of the rapid heating circuit is also connected to an electronic switch in the control lamp circuit, which causes the control lamp to light up continuously.
  • the operator is thereby informed that, since the rapid heating circuit still takes over the power supply to the glow system, the end temperature of the glow system has not yet been reached.
  • the constant up If the control lamp lights up, this indicates to the operator that there is still a need to wait before the internal combustion engine can be started.
