Abstract: A fuel injection system for an internal combustion engine, comprises: a pump comprising a pumping plunger which is driven, in use, to cause pressurisation of fuel within a pump chamber, an accumulator volume for supplying fuel to a fuel injector, a fuel passage providing fluid communication between the pump chamber and the accumulator volume, and an inlet control valve operable to control fuel flow into the pump chamber from a low pressure reservoir; wherein the inlet control valve is a latching inlet valve. The fuel injection system may be a hybrid fuel injection system, having a rail valve located in the fuel passage between the pump chamber and the accumulator volume. The latching inlet valve may be a two-way electronic latching poppet valve, and the rail valve may be a non-return valve. A method of operating such a fuel injection system for an internal combustion engine is also described.

Abstract: The invention is an integrated container structure in which a sealable envelope of flexible material such as plastic, has disposed within it a carton of semi-rigid material which is bonded to the interior of the envelope at one or more places. The carton consists of a sheet of carton material having appropriate fold lines and configuration to be erected or collapsed into a generally flat structure within the envelope. The invention is particularly useful for the shipment of animal products containing bones and has the advantages that it can be stored in a flat configuration and easily erected into an upright carton within the envelope by simple manipulative procedures.
