The present invention relates to a device for direct injection of a gaseous fuel, in particular hydrogen, which device comprises: a pressure-control unit which is designed to convert a supplied variable pressure level of the gaseous fuel into a fixed const...

The invention relates to a method for injecting a gaseous medium, in particular a gaseous fuel, into an intake tract (1) of a gas or diesel-gas engine using an electromagnetically controlled gas valve (2). According to the invention, the gaseous medium is ...

The feed device (12) has, for each cylinder of the engine, a solenoid valve (15) for feeding fuel gas to a corresponding cylinder of the engine. The solenoid valve (15) has at least one shutter (32) carried by an armature of a corresponding electromagnet (...

The heater (10) has fuel intake (42) and outlet, and coolant intake and outlet (56,60). It has an internal section (68) with cylindrical wall, which defines a fuel passage between intake and outlet and separates it from a coolant passage. A control device ...

The two-stage pressure regulator (10) feeds an internal combustion engine of injection type with gaseous fuel taken from a relative tank. The first stage comprises a first chamber (52) communicating with the tank via a first valve (22), a part of the inner...
