System for fuelling combustion chambers (2) of a combustion engine by means of high pressure fuel injection into those combustion chambers of a fuel (7) which is gaseous at atmospheric conditions, e.g. LPG. An injection pressure pump (4,6) is provided for bringing the relevant fuel at the required injection pressure and fuel admission control means (5) for control of the fuel to the combustion chambers. A fuel tank (3) is provided and a fuel pump (6) having its inlet (6a) connected to the fuel tank and its outlet (6b) connected to a fuel circulation circuit (8) which is, at its other side (8b), connected to the fuel tank (3), which fuel circulation circuit is connected, directly or indirectly, to said fuel admission control means. The fuel circulation circuit provides keeping the LPG liquid by using the fuel transfer pump for fuel cooling by circulation through the storage tank (3) and a cooler (9). |
