| 摘要 |
The present invention relates to a supply system (1, 1', 1", 200, 200') for supplying at least LPG to a direct injection engine of a vehicle, said supply system 1, 1', 1", 200, 200') comprising a first reservoir (2, 2', 2", 202, 202') for containing LPG, said first reservoir (2, 2', 2", 202, 202') being devoid of pump, an LPG delivery line (3, 3', 3", 203, 203'), connected at the exit of said first reservoir (2, 2', 2", 202, 202'), at least a first valve mounted on said LPG delivery line (3, 3', 3", 203, 203'), a main return line (18, 18';18", 218, 218'), communicating with said LPG delivery line (3, 3', 3", 203,.203') and connected with said first reservoir (2, 2', 2", 202, 202'), and a single fuel pump (14, 14', 14", 214, 214'), provided along said LPG delivery line (3, 3', 3", 203, 203'), said fuel pump (14, 14', 14", 214, 214') being configured and positioned in such a way to permit transfer of LPG from said first reservoir (2, 2', 2", 202, 202') to said engine, also thanks to the LPG ejection action from said first reservoir (2, 2', 2", 202, 202') due to the pressure exerted by gaseous LPG contained within said LPG reservoir (2, 2', 2", 202, 202'). |
