A device for detecting the start of the injection in a diesel engine works without the usual needle stroke transducer in the injection valve. The output signal of an already available pressure transducer at the output side of the injection pump is used to detect the start of the injection. Further special measures are provided to take into account a coasting operation. Un dispositif de détection du début de l'injection dans un moteur diesel fonctionne sans avoir besoin du capteur habituel de course à aiguille agencé dans la soupape d'injection. A cet effet, le signal de sortie d'un capteur de pression déjà disponible agencé du côté sortie de la pompe d'injection est utilisé pour détecter le début de l'injection. D'autres mesures spéciales sont prévues en cas de marche par inertie.
