摘要：
In a method and device for preheating an internal combustion engine injector (1) including at least one valve (3) to be activated by an electromagnet (21), in which the coil of the electromagnet (21) is energized before the engine is started, the coil of the electromagnet (21) is periodically powered with a preheating voltage (42), and the current characteristic (33) within the coil is monitored and subjected to an evaluation to detect local current minima (43) and/or maxima (44) caused by armature reactions.
