Definitions

  • control means controls, in particular, the safety period, the restarting delay and the retardation time of an auxiliary heating system operable during interruption, or at low outputs, of a main heating system.
  • Such auxiliary heating systems are installed in motor vehicles or ships, and serve to heat the interior of the vehicle or ship adequately when the motor of the vehicle or ship stops or when there is a low output of the heating plant of the vehicle (motor heating plant).
  • cold blowing is meant the blowing out of any ignitable fuel-air mixtures by restarting the combustion air blower and the heating air blower of the heating system. This also serves directly to cool the hot combustion chamber walls.
  • the retardation time also acts in the sense of these safety measures, with the result that the spark plugs or glow plugs of the heating system are shut off only a certain time after ignition of the auxiliary heating system. This has the effect that the ignition of the ignitable fuelair mixture is effected positively, and that no explosion occurs during start-up.
  • auxiliary heating systems In known auxiliary heating systems, the safety period, the restarting delay and the retardation time are controlled, in the electronic devices, by an electrical discharge, which provides the switching signal. Discharge is effected by the series connection of an electrolytic capacitor and an ohmic resistor, which together form a time constant and which start an operation, for example, shutting off of the system, when a certain voltage level is attained.
  • the invention is directed to providing means by which the control durations for the safety time, the restarting delay and the retardation time, to be maintained for the safety of operation of an auxiliary heating system, can be easily and safely set independently of the temperature and of the voltage over wide ranges, and can also be maintained in operation.
  • the means provided by the invention it is possible to count the pulses originating from the interrupter contact of the combustion air motor of the vehicle or ship, and to provide, at various points, logical outputs which initiate operations in the auxiliary heating system.
  • This has the advantage that the duration of the safety time need no longer be indicated in minutes or in any other units of time, but rather is indicated in pump strokes and thus in a measure which enters directly into the behavior of the pump.
  • This has the additional advantage that the amount of fuel, for example, which is injected into the heater, is accurately defined by the number of pump strokes independently of the voltage. Thus, it can no longer happen that a heater running with 15 volts battery voltage injects slightly more fuel than when operating with 12 volts or even with 9 volts.
  • the pulse counter feeds a pulse to the control device only after the pulse counter has received a preselected number of pulses transmitted by the pulse transmitter.
  • the effect of this is that an operation controlled by the control device is started only when a very definite number of pulses has been counted.
  • the individual control times or durations can be selected freely.
  • the pulse transmitter, as well as the pulse counter, the decoder and the control device can be combined to form a unit. This has the advantage of extreme compactness, and it is also suitable for the subsequent installation in existing auxili ary heating systems.
  • An object of the invention is to provide improved means for controlling the course of operation of an auxiliary heating system in motor vehicles or in motordriven ships.
  • Another object of the invention is to provide such a means by which the control times ,for the safety period, the restarting delay and the retardation time of an auxiliary heater can be easily and safely set independent of temperature and voltage over wide ranges.
  • a further object of the invention is to provide such a means utilizing a single pulse transmitter in association with a pulse counter, a decoder and a control device.
  • FIGURE is a simplified schematic diagram of a control means embodying the invention.
  • a permanent magnet 3 is arranged on the shaft 2 of a motor 1, and forms, with stationary inductance coil 5, a pulse transmitter 4.
  • the pulses 6, originating from pulse transmitter 4, have a certain pulse sequence.
  • the pulse sequence depends on the speed of motor 1.
  • the pulse sequence of the output pulses 6 can be preset.
  • Pulses 6 are fed to a pulse counter 8 with an attached decoder 9 and to a control device 11.
  • Pulse counter 8 counts the number of pulses independently of the pulse frequency and, after a given number of pulses has been counted, selected pulses 10 are supplied to control device 11.
  • Control device 11 controls, by means of output pulses l2, pump 13, heating air blower 14, ignition device 15 and the safety switch 16 of the auxiliary heating system.
  • Pump 13 is a fuel dosing pump, which is driven electromagnetically by current pulses l2, and which feeds the fuel in pulses to the combustion chamber of the auxiliary heating system.
  • control durations or periods or times can be set very accurately over wide ranges independently of the voltage.
  • auxiliary heating system for supplementing or augmenting a main heating system, of a motordriven vehicle, and including a main motor having a drive shaft, and of the type including, as components, a heat exchanger independent of the main system, a fuel pump, a heating air blower, an igniter for a fuel burner, and a safety switch, and further including a control device for its components: means for controlling the safety period, restarting delay, igniter operating time and safety switch of the auxiliary heating system, said means comprising, in combination, pulse generating means including a single pulse transmitter, constituted by a permanent magnet on said drive shaft and a stationary magnetic field responsive element opera tively associated with said permanent magnet providing output pulses for controlling the operation of said auxiliary heating system; a pulse counter connected to said transmitter to receive and count such output pulses; a decoder connected to the output of said pulse counter to receive counted output pulses therefrom; and a pulse responsive control device, controlling the operation of said auxiliary heating system components, connected to said decoder to receive such output pulse
  • Means for controlling operation of an auxiliary heating system as claimed in claim 1, in which said pulse transmitter comprises a permanent magnet on the shaft of a drive motor; and a stationary inductance coil cooperable with said permanent magnet,
  • Means for controlling operation of an auxiliary heating system as claimed in claim 1, in which said pulse transmitter comprises a permanent magnet on the shaft of a drive motor; and a stationary magnetically controlled resistor cooperating with said permanent magnet.
  • Means for controlling operation of an auxiliary heating system as claimed in claim 1, in which said pulse counter transmits an output pulse to said control device only after said pulse counter has received a preselected number of output pulses from said pulse transmitter.
  • Means for controlling operation of an auxiliary heating system as claimed in claim I, in which said pulse transmitter, said pulse counter, said decoder and said control device conjointly form a unit.
