Definitions

  • the invention relates to a method and a circuit arrangement for heating a glow plug of a given glow plug type in a given arrangement in an internal combustion engine to a predetermined temperature.
  • Glow plugs are used, for example, in diesel engines Ignition of the fuel when starting or also for ion current detection used in the combustion chamber of a diesel engine.
  • Glow plugs are known which are self-regulating Have heating characteristics. These are timed to one Supply voltage switched and heat due to their self-regulating behavior to the specific temperature.
  • glow plug It is also known to heat a glow plug electronically to regulate.
  • the glow plug supplied electrical power via an electronic control circuit regulated so that the predetermined certain temperature reached as quickly as possible and not exceeded.
  • the object underlying the invention is therefore therein, a method and circuitry for heating specify a glow plug that allows heating within a very short time interval to a relatively high temperature can be achieved.
  • the circuit arrangement according to the invention is the subject of Claim 3.
  • FIG. 1 In the known steel glow plug 1 shown in FIG. 1 is an electrically operated heating device 4 in a glow tube 3 embedded.
  • the glow tube 3 is seated in a glow plug body 5, through which the glow plug 1 is screwed into the engine block.
  • the Power is supplied to the electrical heating device 4 via a electrical connection 7, with the electrical heating device 4 is connected.
  • the second electrical connection of the heater 4 is connected to the glow tube 3, so that on the Glow tube 3 and the glow plug body 5 the circuit to ground 8 is closed.
  • Glow plug 1 can also be designed as a ceramic glow plug be in which the glow tube 3 and the heater 4 in shape a unit are designed as a ceramic heating element.
  • the glow plug 2 shown in FIG. 2 is around an electrically insulated steel glow plug for Ion current detection in the combustion chamber of an internal combustion engine.
  • the Glow tube 3 is electrically insulated from candle body 5 arranged and serves as a measuring electrode in ion current detection.
  • a semiconductor switch 9 and Voltage evaluation circuit 10 arranged depending on the voltage across the glow plug 2 is the semiconductor switch 9 for heating to the conductive state or for ion current detection in the locked state.
  • the self-regulating heating characteristic can be, for example thereby achieve that the heating device from a heating coil and a control coil is built up. These coils are in series switched.
  • the heating coil consists of a material with negligible small temperature coefficient, while the Control coil made of a material with a clear temperature coefficient consists.
  • Heating up a glow plug can also be done electronically regulated take place, in which case that of the glow plug supplied electrical power via an electronic control circuit is regulated so that a predetermined temperature reached as quickly as possible and not exceeded. If the Heating device made of a material with a known resistance temperature behavior is constructed from one Current and voltage measurement of the resistance and thus the Determine the temperature of the heating device.
  • the initial conditions are the initial temperature, the cooling conditions and the heat capacity of the area to be heated Glow plug, which is a delimited area of the Glow plug, that is the glow tube and especially the glow plug tip acts. This area has a defined heat capacity.
  • the cooling conditions are determined by the arrangement or the Installation of the glow plug in the engine is determined and can be done by calculation or determined by measurement.
  • the heat capacity of the Glow plug, that is, its area to be heated on the Glow plug tip is due to the geometry and the material properties determined and can also by calculation or can be determined by measurement. It can be assumed be that with regard to the manufacture of glow plugs in large quantities, the cooling conditions and the heat capacity of glow plugs of the same glow plug type only slight scatter subject to.
  • the energy required for heating a glow plug from an initial temperature to the desired one or predetermined final temperature by measurement and / or by Calculation can be determined and that with glow plugs the same glow plug type in the same arrangement heating can be controlled so that in the heating phase always same predetermined, for heating the glow plug to the predetermined temperature required and by measurement or Calculation determined heating energy is supplied.
  • Others Starting or ending temperatures can be other needed Assign heating energies. If the heating energy supply is electronic is controlled, the supply of heating energy per time that is called the absorption of electrical power, controlled arbitrarily become. For example, the power consumption can be constant can be held or initially more and then less, or conversely, power can be supplied.
  • FIG 3 shows an exemplary embodiment in a schematic arrangement the inventive arrangement for heating a glow plug of a given glow plug type in a given Arranged at a predetermined temperature.
  • a glow plug 1, 2 of the type shown in FIG. 1 or 2 is connected to the supply voltage U B via a switch S11 and a current measuring resistor R M 12.
  • a voltage U M proportional to the glow plug current I GK can thus be tapped at the taps 13, 14 via the resistor R M 12.
  • the voltage U GK at the glow plug can also be measured via the tap 14.
  • the tapped voltages lie on a control and evaluation unit 16, which can be designed, for example, in the form of a microprocessor with an integrated analog / digital converter.
  • This control and evaluation unit 16 controls the switch 11 via its output signal 15.
  • the combination of the switch 11 and the current measuring resistor 12 is preferably implemented as a fully integrated power semiconductor with a load current signal output.
  • a signal for closing the switch 11 is applied via the control and evaluation unit 16.
  • the supply voltage U b is applied to the glow plug.
  • the total heating-up time interval is divided, for example, into individual short part-time intervals T 0 and the taps 13, 14 are used to determine the voltage U A at the glow plug and its current consumption I GK .
  • the total heating energy supplied is then obtained by adding up these individual heating energies in the short part-time intervals T 0 .
  • the supply of heating energy can then be controlled by the fact that, for example, the Bacaufloomzeitintervall in ten component time intervals T is divided 0 and the switch 11 is not closed in all ten time intervals T 0, but for example, only three out of ten time intervals so that the glow plug at constant energy input per Time interval only 30% of the maximum possible heating energy is supplied.
  • the partial heating energy quantity supplied in each partial time interval is determined and added, and the switch 11 remains closed until the required predetermined total heating energy is reached, which is required for heating the glow plug to the predetermined temperature.
  • the supply of heating energy ensures that a Damage to the glow plug when feeding the Heating energy occurring heating power is excluded.
  • a predetermined limit the maximum temperature of the heating element in the glow tube the glow plug for example the heating and control coil, below its melting temperature is not exceeded.
  • the Arrangement of a heating element inside a glow tube and the Embedding the heating element in the glow tube is one possible Form of training that represents a thermal low pass, in which the temperature of the heating element during rapid heating compared to the temperature of the glow tube much faster increases.
  • the energy supply during the rapid heating up will controlled so that the temperature of the heating element never the exceeds the predetermined limit.
  • This low pass behavior of the Glow plug is given by its structure. In this way an energy or performance-time profile can be defined overheating of the heating element during fast Prevents heating.
