This paper describes a fuel vaporizer for creating continuously variable fuel vapor air mixtures at engine intake. It comprises: a piston internal combustion engine mechanism; an outer hollow cylinder; an inner solid member; means for rotating the outer cylinder about the centerline of symmetry; means for positioning the inner solid member inside the outer cylinder; a liquid fuel supply source; means for spreading liquid upon the inner surface of the outer cylinder; means for metering liquid fuel and transferring the metered liquid fuel quantity from the supply source to the liquid spreader means; means for heating the outer cylinder; an air inlet; a fuel air mixture pipe; means for connecting the air inlet to the inlet end of the outer cylinder so that the engine intake air flows inside the outer cylinder; means for connecting the inlet end of the fuel air mixture pipe to the outlet end of the outer cylinder and the outlet end of the fuel air mixture to the inlet of the engine intake manifold so that fuel mixture created inside the outer cylinder passes through the fuel air mixture pipe and into the engine intake manifold.
