The invention relates to a cranking device for internal combustion engines, having a starter motor whose starter pinion initially shifts into the gear ring of the engine with a starting signal via an engagement magnet, before the starter motor trips the cranking process with full force. The shifting of the starter pinion and the switching of the starter motor are improved by providing that the starter motor (SM) with the starting signal (st) drives the starter pinion initially via a protective resistor (Rvor) with reduced torque, and the engagement magnet (EM) shifts it into the gear ring of the engine, and that after that, the engagement magnet (EM) presses the starter pinion all the way into the gear ring of the engine, and the starter motor (SM) turns the engine over with full torque by bypassing the protective resistor (Rvor).

A measuring element for determining the flow rate of the aspirated air of an internal combustion engine comprising a substrate, which is divided by two parallel separating slits of equal length into three prongs on which temperature-dependent resistor tracks are disposed. The measuring element has separating slits of optimized shape. To lessen the notch action and reduce tension peaks at the ends of the slits, one separating slit has a segment with a curved course, and another separating slit has a slit end embodied as an enlargement. The novel measuring element is especially suitable for determining the flow rate of the aspirated air in internal combustion engines.
