The engine of the present invention provides the direct transfer of energy from the burning down of fuel in the engine cylinders into shaft power by forcing working liquid through guide devices and against an impulse turbine, thereby eliminating the need for supplemental pumps and the usual power losses associated therewith, thus improving the fuel consumption to power output ratio. In addition the engine of the present invention provides an internal combustion engine characterized by a crankshaftless design which meets all of the requirements for operation over the speed ranges necessary for a wide range of the propulsion systems, such as but not limited to, cars, and trucks of all sizes, rail traction, and marine propulsion.
