ABSTRACT:
Method and group for feeding LPG to an internal combustion engine according to which during some engine operation instants the temperature of the LPG fed to injectors is determined and, for each temperature value, a correspondent value of a maximum optimal pressure is determined so that LPG remains in gaseous phase; an incoming LPG real pressure to the injectors is adjusted so that it is substantially the same of maximum optimal determined pressure and the gas flow from injectors is controlled according to the adjusted effective pressure of engine inlet camera and of the LPG temperature.
