Definitions
- the invention relates to a method for heating a electric heating element, in particular a glow plug Internal combustion engine, from an initial temperature to the operating temperature.
- an electrical heating element such as one Glow plug in steel or ceramic design or another Heating element, such as a heater or a Heating flange
- a heating element for a limited period of time operated with a voltage higher than the operating or Design voltage of the heating element is.
- Design voltage of a heating element that voltage at which the heating element in the steady state its operating parameters, in particular its desired or necessary surface temperature, has achieved and maintains.
- the thermal power output equal to the electrical power consumed.
- the heating process differs from the stationary one Operating state in that the heating element for a limited Time a higher power is supplied. That is required because the heating element is a mass-based arrangement represents and thus forms a heat capacity. This heat capacity must be filled when heating up. To do this is a certain one Amount of energy required during the heating process the heating element must also be supplied. By this additional amount of energy increases during the heating process the temperature of the heating element from its initial temperature to the operating temperature.
- the object underlying the invention is therefore in specifying a method of the type mentioned at the beginning with overheating of the heating element, that is, heating of the heating element to above the operating temperature lying temperature can be avoided at which the heating element is damaged or even destroyed.
- this object is achieved by that the initial temperature of the heating element is determined and the heating element is supplied with electrical energy for heating the height of which is determined from the determined initial temperature depends.
- the initial temperature is thus of the heating element, so that using given the operating temperature to be overcome Temperature difference and thus the electrical energy determined that is required to remove the heating element from the determined initial temperature to the operating temperature bring. This can prevent overheating.
- a voltage U B2 which is above the voltage U B1 which is in the stationary state on the heating element is usually applied to the heating element when heating an electrical heating element for a certain time t A.
- the temperature according to FIG. 1 increases from an initial temperature T 01 to the operating temperature T B.
- the heating element is heated to the temperature T S with the same electrical energy supplied, which is above the operating temperature T B. If this temperature is close to the melting temperature of the material of the heating element or even reaches the melting temperature, the heating element is damaged or destroyed.
- the starting temperature of the heating element is determined in the method according to the invention and the heating element is supplied with electrical energy for heating, the amount of which depends on the determined starting temperature. If, for example, the initial temperature T 02 is determined, the heating element is supplied with a smaller amount of electrical energy than is the case when the initial temperature T 01 . It is thereby achieved that even at an initial temperature T 02 , which is above the temperature T 01 , the temperature only increases to the operating temperature T B in the course of the heating process.
- the time over which the heating element is operated with the higher operating voltage U B2 is determined as a function of the determined initial temperature. In other words, the voltage U B2 is supplied at a higher starting temperature T 02 only for a time which is less than the time over which this voltage U B2 is present when the starting temperature is equal to the preset value T 01 . The time over which the higher voltage U B2 is applied is thus selected such that thermal overloading of the heating element is prevented.
- the two voltages U B1 and U B2 can be achieved by selecting the vehicle electrical system voltage of the vehicle as the higher voltage U B2, for example in the case of a glow plug, and the operating voltage U B1 , which is below this voltage, by clocking, for example by pulse width modulation, of the voltage U B2 is generated. This effectively reduces the effective voltage, that is to say the effective voltage at the heating element, from U B2 to U B1 .
- Fig. 2 shows the circuit diagram of a circuit arrangement for Implementation of the method according to the invention.
- 2 is an electrical heating element 1 is shown.
- electrical Heating elements have a temperature-dependent resistance due to the physical properties, for example the Resistance temperature coefficients of their materials and / or of their inner structure. This applies to metallic heaters, glow plugs with heating and control coils, auxiliary heater with cold heating elements PTC and similar electrical heating elements.
- the starting temperature of the heating element 1 its electrical resistance R T is determined before the heating process begins, and the starting temperature is determined therefrom via the temperature coefficient of the material of the heating element.
- the electrical resistance R T the current I H and the voltage U H of the heating element are measured and the resistance R T is calculated therefrom.
- the circuit arrangement shown in FIG. 2 further comprises a microprocessor 7 with an analog / digital converter at which voltage taps 4 and 5 are located on both sides of a measuring resistor 3, which is connected to the heating element 1 via a switch 2.
- the microprocessor 7 applies a control signal 6 to the switch 2, by means of which it is opened and closed.
- the operating voltage U B is at the measuring resistor 3.
