Abstract (en)
[origin: WO2007112462A1] In a method and a device for preheating injectors (1), having at least one valve (3) which can be activated by an electromagnet (21), of internal combustion engines, in which the coil of the electromagnet (21) is energized before the engine is started, a preheating voltage (42) is periodically applied to the coil of the electromagnet (21), and the current characteristic (33) in the coil is monitored and evaluated in order to detect local current minima (43) and/or current maxima (44) caused by armature reactions.
