Abstract: A module for managing mass flow and dampening pressure pulsations in the supply line of a gaseous fuelled internal combustion engine comprises a hollow body defining an expanded volume that is fluidly connected directly to a pressure sensor and a temperature sensor. The module is placed along the supply line of a gaseous fuel engine between a fuel pressure increasing device and the fuel rail that supplies fuel to the engine. The module can comprise a filter that filters the impurities from the gaseous fuel supplied to the engine and an overpressure protection device that can vent some of the gaseous fuel from the module to protect it from over-pressurization.
