  • Detection device which comprises a reflection part, in particular a reflection plate.
  • the emitting part of the optical detecting means emits rays which are reflected by the reflecting part and detected by the detecting part.
  • a correction value is read in accordance with the detected rotational position, by means of which the detected position is corrected.
  • the detection of the position of the actuating part makes it possible to check whether the position of the actuating part is at least substantially within a certain range and thus the actuating device or the actuating part has a desired functionality. If the position is outside this range, this indicates a malfunction of the control part, so that appropriate countermeasures must be taken to avoid damaging operation of the reciprocating engine or the actuator or operation of the reciprocating engine with an undesirably high energy consumption and undesirably high emissions.

Abstract

L'invention concerne un procédé pour faire fonctionner un moteur à piston alternatif, en particulier pour un véhicule à moteur, selon lequel un taux de compression d'au moins un cylindre du moteur à piston alternatif, dans lequel un piston (30) est logé en étant guidé de manière à effectuer des mouvements de translation, est ajusté au moyen d'un dispositif de réglage (38) correspondant au cylindre, un élément de réglage (36), en particulier un piston de commande (36), maintenu mobile sur un guide (41) du dispositif de réglage (38) est déplacé entre au moins deux positions, le taux de compression établi étant déterminé en fonction d'au moins un signal acquis au moyen d'au moins un dispositif d'acquisition (50) et caractérisant au moins une des positions.
