A device for heating the glow plugs of internal combustion engines, particularly in flame starting systems, in which there is provided a retriggerable monostable time function element which is triggered if a control voltage exceeds a specific value, and a continuous and subsequently a pulsatory current being supplied until the end of the stationary time of the retriggerable monostable time function element of the glow plug, there being provided a temperature switch which switches on below a specific first engine temperature value and switches off above a specific second engine temperature value and through which the operating voltage is applied to the device. The intended achievement is that the heating of the glow plug is reduced only if the internal combustion engine has run for a specific period of time. |
