METHOD AND DEVICE FOR MONITORING THE DIRECTION OF ROTATION OF A PISTON ENGINE

摘要

The invention relates to a method and device for recognizing the direction of rotation of a piston engine, particularly of an internal combustion engine or of a piston compressor. The aim of the invention is to identify the direction of rotation of the piston engine in a reliable, early and simple manner. To this end, the pressure prevailing inside the intake port (7) is measured during a identified direction of rotation, is compared to a predeterminable threshold value, and the direction of rotation of the piston engine is determined based on the result of this comparison. A throttle device (11) is closed at least for the duration of the pressure measurement.
