SUPPLYING GASEOUS FUEL FROM A LIQUID STATE TO AN INTERNAL COMBUSTION ENGINE

摘要

There is an improved apparatus for supplying gaseous fuel from a liquid state to an internal combustion engine comprising an electrical energy generating apparatus for generating electrical energy from a store of chemical energy; a liquid pumping apparatus for pumping the gaseous fuel in the liquid state comprising an energy converter for converting the electrical energy to mechanical energy which drives the liquid pumping apparatus; a first heat exchanger for vaporizing the gaseous fuel received from the pumping apparatus; and a controller programmed to operate the liquid pumping apparatus to maintain a pressure of the gaseous fuel supplied to the internal combustion engine within a predetermined range.
