Title
(EN) VEHICLE FUEL TANK MANAGEMENT
(FR) GESTION DU RESERVOIR DE CARBURANT D'UN VEHICULE
Abstract
(EN)
A vehicle engine management system includes a single engine control unit (4) with a control/processor (22) and store devices (23-25). The vehicle can be powered by gas fuel from tank (27) via gas injectors (6) or by petrol from tank (8) via petrol injectors (2). The control (22) determines whether gas or petrol is utilised dependent on driving conditions using mapping (23, 24). To refuel the vehicle a cycle of operations is carried out by control (22) using the sequences stored in device (25). The presence of a connected gas supply is determined via detector (13a) and gas tank pressure via sensor (27a) and a compressor (28) is operable during the cycle to refuel the tank. Refilling automatically terminates and after this the car can be driven away when fuel line decoupling is detected.
(FR)
L'invention concerne un système de gestion du réservoir de carburant d'un véhicule équipé d'une unité de commande du moteur (4) dotée d'un processeur (22) et de dispositifs de stockage (23-25). Le véhicule est alimenté en gaz provenant d'un réservoir (27) et conduit par des injecteurs de gaz (6) ou en essence provenant d'un réservoir (8) conduite par des injecteurs d'essence (2). Le processeur (22) détermine quel carburant il faut utiliser selon des conditions de conduite grâce à une représentation (23, 24). Pour faire le plein du véhicule, le processeur (22) met en route un cycle d'opérations grâce à des séquences stockées dans le dispositif (25). Un détecteur (13a) détermine la connexion d'un pistolet de distribution de gaz et un détecteur (27a) détermine la pression du réservoir de gaz. Un compresseur (28) peut fonctionner pendant le cycle consistant à faire le plein. Une fois le remplissage automatique terminé, la voiture ne peut être démarrée que lorsque le pistolet de distribution du carburant est retiré du réservoir.
