DEVICE FOR INJECTING A GAS FUEL IN LIQUID FORM FOR AN INTERNAL COMBUSTION ENGINE COMPRISING MEANS OF HEAT TRANSFER

摘要

The invention concerns a device for liquid-phase injection of a fuel having a boiling point lower than room temperature, at atmospheric pressure, in an intake conduit (6) of an internal combustion engine, said device comprising at least an injector (1) fixed on the base of an intake distributor (7) and at least a transport channel (10, 14) for the fuel between the injector outlet and the intake conduit. The invention is characterised in that the channel (10, 14) comprises means for transferring heat (8) between a hot part (9) of the engine and a portion of the channel inner wall.
