Abstract

Dans un système d'échauffement automatique pour un moteur à combustion interne et une pompe hydraulique, les informations provenantn des capteurs de température (10, 15, 13), destinés à détecter les températures de l'huile lubrifiante et de l'eau de refroidissement dans un moteur à combustion interne (2) et la température de l'huile dans un réservoir hydraulique (12) d'un système hydraulique, sont envoyées à un organe régulateur (1) du moteur, destiné à commander la position d'une crémaillère dans une pompe d'injection de carburant (3). L'organe régulateur (1) produit une commande d'échauffement du moteur à une vitesse de rotation déterminée en fonction des informations provenant desdits capteurs de température. A mesure que l'échauffement du moteur augmente et lorsque l'organe régulateur (1) détermine que le niveau d'une sortie du moteur à combustion interne dépasse le niveau requis, en fonction des informations provenant du capteur de position (11) sur la crémaillère, le niveau de sortie excessif du moteur est envoyé sous forme d'un signal de charge du moteur à un régulateur hydraulique (4). La vitesse de décharge et la pression de décharge d'une pompe hydraulique (5) sont déterminées par le régulateur hydraulique (4) de manière que leurs niveaux correspondent au niveau de sortie excessif du moteur à combustion interne. Grâce à ces opérations, l'échauffement du moteur à combustion interne et de la pompe hydraulique peut s'effectuer automatiquement avec un rendement élevé pendant la durée de temps nécessaire.
