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.
A multifunctional module for managing mass flow and dampening pressure pulsations in a gaseous fuel supply line of an internal combustion engine, said module comprising:
A multifunctional module for managing mass flow and dampening pressure pulsations in a gaseous fuel supply line of an internal combustion engine, said module comprising:
A fuel supply line of an internal combustion engine for supplying a gaseous fuel from a fuel tank through a pressure increasing device to a fuel rail that delivers fuel to a fuel injector of said engine, said fuel supply line comprising a multifunctional module for managing mass flow and dampening pressure pulsations in said gaseous fuel, said module being located along said fuel supply line whereby said gaseous fuel that flows between said pressure increasing device and said fuel rail must flow through said module which has a hollow body defining an expanded volume that is fluidly connected to (a) a pressure sensor which measures pressure within said expanded volume, and to (b) a temperature sensor which measures temperature within said expanded volume and respective pressure and temperature measurements taken by said pressure and temperature sensors are communicated to a controller which stops or activates said pressure increasing device to maintain a pressure within said module within a predetermined pressure range.
A method of managing mass flow and dampening pressure pulsations generated by a pressure increasing device in a gaseous fuel supply line of an internal combustion engine, the method comprising:
