MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647123943 A) filed by Phinia Delphi Luxembourg Sarl on October 16, 2026, for Fuel Gas Supply System With Enhanced Leak Detection.
Inventors include Van Den Hende, Stphane; and Fournier, David.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention relates to a gaseous fuel delivery system for supplying an injection rail (32) equipped with fuel injectors (33, 34, 35, 36), each injector intended to provide a cylinder of a combustion engine with fuel gas, said system including a plurality of sections (1, 2, 3), each of which being separated from an adjacent section by at least one shut-off valve (11, 21, 31). The system according to the invention further includes:. a plurality of sensors for assessing fuel gas pressure and temperature values (P, T) within said sections; and. a computing module (50) configured to calculate a cumulated quantity of fuel gas injected in the engine through the injectors between a first and a second instant. The system is further configured to:.compute an input value defined as a difference value between a first and a second value of fuel gas mass enclosed within said system at a said first and second instants on the basis of fuel gas pressure and temperature values (P, T) established at said first and second instants for each section;. determine an output value defined as a value of fuel gas mass injected through the injectors between said first and second instants on the basis of the calculated cumulated quantity; and issue an alarm signal if a difference between said input and output values is greater than a predetermined threshold value. The invention enables to take into account the effects of possible fuel gas expansion and compression occurrences which are currently overseen in known supply systems.
