Description

DESCRIPTION
La présente invention est destinée à permettre l'établissement et le contrôle des courbes d'avance sur moteur diesels et à mesurer la vitesse de rotation de ces moteurs, en utilisant des appareils de mesure et de contrôle prévus pour les moteurs à essence.DESCRIPTION
The present invention is intended to allow the establishment and control of the advance curves on diesel engines and to measure the rotational speed of these engines, using measuring and control devices provided for petrol engines.

Le contrôle des courbes d'avance diesel se faisait précédemment exclusivement à l'aide du matériel spécifique. La présente invention permet, grâce à une adaptation simple, de se servir des équipements très répandus de contrôle pour moteurs à essence, munis d'une pince à induction. The control of the diesel advance curves was previously done exclusively using specific equipment. The present invention makes it possible, by means of a simple adaptation, to make use of the widely used control equipment for petrol engines, provided with an induction clamp.

D'autre part, le capteur optique est une innovation utilisable tant avec du matériel de mesure diesel spécifique, en remplacement des capteurs piézo-électriques utilisés jusqu'à présent, qu'avec des appareils de mesure pour moteurs à essence en utilisant le dispositif d'adaptation
Le moment d'injection peut être détecté à l'aide d'une pince piézoélectrique (2 fig.2),.à l'aide d'un capteur piézo-électrique intercalé dans le circuit d'injection (2-3 fig.3), ou à l'aide du capteur optique (2-3*fig.4)
L' impulsion est transmise par le cable 1 au boitier contenant l'amplificateur (2fig.l). Le signal amplifié est transmis dans la boucle (3 fig.l)
Le signal est comparable à celui qui traverse le faisceau d'allumage des moteurs à essence, et peut, de ce fait, être capté par la pince à induction (4 fiv.1) reliée aux appareils de mesure prévus pour ces moteurs
Le capteur optique (fig.4), est constitué par une bougie creuse (2) usinée de telle façon qu'elle puisse être vissée à la place de la bougie de préchauffage, étant donc de dimensions forme et filetage identiques à ceux des modèles standard de bougies. Cette bougie est alésée de part en parts et est équipée d'une fenêtre en matière transparente et d'une vis creuse de fixation de cette fenêtre. La partie supèrieure de la bougie permet de fixer une cellule photo-électrique (3).On the other hand, the optical sensor is an innovation usable both with specific diesel measurement equipment, replacing the piezoelectric sensors used until now, as with measurement devices for gasoline engines using the device of 'adaptation
The injection moment can be detected using a piezoelectric clamp (2 fig.2), using a piezoelectric sensor inserted in the injection circuit (2-3 fig.3 ), or using the optical sensor (2-3 * fig.4)
The pulse is transmitted by cable 1 to the box containing the amplifier (2fig.l). The amplified signal is transmitted in the loop (3 fig.l)
The signal is comparable to that which passes through the ignition beam of petrol engines, and can therefore be picked up by the induction clamp (4 fiv. 1) connected to the measuring devices intended for these engines.
The optical sensor (fig. 4) consists of a hollow plug (2) machined in such a way that it can be screwed in place of the glow plug, therefore being of identical shape and thread dimensions to those of standard models candles. This candle is bored right through and is equipped with a transparent material window and a hollow screw for fixing this window. The upper part of the candle allows to fix a photocell (3).

L'intérêt du capteur optique est d'éviter de devoir déconnecter les tuyaux d'injection poUr intercaler un capteur de pression, ce qui fait courir le risque d'introduire des limailles capables de boucher ou d'abîmer les nez d'injecteurs. Il est également plus fiable que les pinces piézo-électriques utilisées pour détecter les déformations des tuyaux d'injection lors des crêtes de pression. The advantage of the optical sensor is to avoid having to disconnect the injection pipes in order to insert a pressure sensor, which runs the risk of introducing filings capable of clogging or damaging the injector noses. It is also more reliable than the piezoelectric clamps used to detect deformations of the injection pipes during pressure peaks.

Le dispositif d'adaptation permettant d'utiliser du matériel de mesure pour moteurs à essence pour régler des moteurs diesel permet d'éviter un investissement dans du matériel spécifique coûteux, lorsque le mécanicien ne s'occupe qu'occasionnellement de moteurs diesel, ou que ses moyens ne lui permettent pas de faire cette dépense.  The adaptation device making it possible to use measuring equipment for petrol engines to adjust diesel engines makes it possible to avoid an investment in expensive specific equipment, when the mechanic only occasionally deals with diesel engines, or when his means do not allow him to make this expense.
