Abstract: Dispositif pour l'alimentation mixte au gaz pauvre et au gazole d'un moteur Diesel.
Dispositif d'alimentation mixte au gaz pauvre et gazole pour un moteur Diesel, équipant plus particulièrement un véhicule routier et caractérisé par le fait que le gaz, produit par un générateur (4 à 30), arrive au moteur (32) directement et sans retenue, sauf au régime de ralenti, la puissance étant réglée essentiellement par l'injection d'une quantité minimum de gazole qui ne sert qu'à atteindre la température d'inflammation du gaz pauvre et à régler le régime du moteur.

Abstract: Various methods and systems are provided for an intake manifold for an engine. In one example, an insert comprises an annular body having a top surface, bottom surface, inner surface, and outer surface. The insert further comprises a first groove for coupling an intake air port of an intake manifold to a cylinder head, a second groove for circulating gaseous fuel received from a gas runner of the intake manifold, and one or more openings to fluidically couple the second groove to an interior of the intake air port. The insert is configured to mix gaseous fuel and intake air at a coupling location between the intake manifold and the cylinder head.

Abstract: A dual-fuel engine has a primary fuel supply and a secondary fuel supply, the primary and secondary fuels being arranged in use to mix with each other and with air for combustion in one or more cylinders of the engine. The supply of both the primary and secondary fuels is arranged to be actively managed in accordance with a desired engine performance characteristic by an electronic controller. In one arrangement the supply of a primary fuel is arranged to be actively reduced when a secondary fuel is supplied to the engine.

Abstract: A dual fuel engine (2) is provided which is supplied with diesel fuel and at least one secondary fuel, such as LPG. The engine (2) has a plurality of cylinders (4, 6, 8, 10) in which pistons reciprocate. Each cylinder has diesel injectors (4A ,6A, 8A, 10A) for injecting the diesel fuel into the cylinder during an appropriate stroke of the piston and an air inlet valve (4C, 6C, 8C, 10C) which opens during the appropriate stroke of the piston to permit air flow therethrough. Each cylinder is further provided with LPG injectors (4B, 6B, 8B, 10B) for injecting the secondary fuel into the cylinders. The LPG injectors are independent to and separate from the diesel fuel injectors. The LPG and diesel fuel injectors are also independently controlled.

Abstract: A control box (11) for a dual-fuel internal-combustion engine (6) is actuated automatically by an oil-pressure switch (16) when activated by a manual switch (30) that directs power from a battery (29) or other engine-electrical component to a current distributor such as a 24-volt bus (49) for operating control-box components that include an under-current sensor (36) for preventing use of gaseous fuel in addition to liquid fuel under no-load and low-load conditions, an over-current sensor (39) for preventing use of gaseous fuel in addition to liquid fuel under excessive-load conditions, an intake-air sensor (17) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of air, a liquid-fuel-supply sensor (22) for preventing use of gaseous fuel with liquid fuel when there is inadequate supply of liquid fuel, and an exhaust-gas-temperature monitor (23) for shutting down dual-fuel mode when exhaust heat is excessive.

Abstract: 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.
