ABSTRACT:
Disclosed herein is an internal combustion engine comprising a plurality of cylinders respectively including a head end, an exhaust port, and a pressure port located between the head end and the exhaust port, a like plurality of pistons respectively movable in the cylinders through respective compression strokes, a like plurality of fuel injectors respectively connected to the cylinders and operative to supply, from a fuel source to each of the cylinders, a metered quantity of fuel conveyed by compressed gas in response to fuel injector operation during the compression stroke of the associated cylinder, a storage tank for accumulating and storing compressed gas, a duct system including a selector value for selectively connecting the pressure ports to the storage tank only during the compression strokes of the associated cylinders, and a conduit connecting the storage tank to the fuel injectors for supplying the fuel injectors with compressed gas in response to fuel injector operation.
