PROBLEM TO BE SOLVED: To provide an improved fuel consumption movable deformation cam for increased fuel consumption efficiency of cars. SOLUTION: For power plant and transmission gear to move cam and camshaft which integrates two kinds of cams in a normal engine, a normal cam composed of semicircle and half oval, besides this the half oval part rotated 180 degrees is made to match it; or a new cam with a somewhat smaller half- ellipse portion rotated by 180 degrees is made to be incorporated in the direction of the same centerline; and when a piston is at an inhalation process, inhalation cam is actuated, at the time of exhaust-gas stroke, an exhaust cam actuates the cam-shaft position of a normal cam, at compression stroke of a piston a normal cam is not operated besides an exhaust cam; and also at explosion process inhalation cam is operated whereas an usual cam is not operated, because it chooses a new camshaft position for movable transformation unified camshaft.
