Claim:
An external combustion engine system for motor vehicles that does not use a transmission and cooling components, consisting essentially of: a dual firing chamber comprising: an air intake with a flapper valve for solely letting fresh air into the dual firing chambers; a fuel storage supply having an output for metering fuel therefrom; a dual firing chamber area to receive the fresh air and having fuel injection connections for alternately injecting the metered fuel from the fuel storage supply into each chamber of the dual firing chamber; and a dual igniter for alternately igniting fuel inside each chamber to generate pressure inside of the dual firing chamber; a pressure storage chamber to store pressure generated in the dual firing chamber; a pressure conversion unit connected with a pressure regulator relief valve located between an output of the pressure storage chamber and the pressure conversion unit, the pressure conversion unit comprising: an oscillating cylinder with a cylinder head intake and exhaust valves at each end and containing a double acting piston being driven by the generated pressure in the pressure storage chamber; and a rotatable crank driven by the double acting piston for rotating a geared crank power wheel, wherein at least two power strokes are generated for each single crank rotation; and a geared power accumulator rim rotated by the geared crank power wheel.
