A crankshaft of the piston reciprocating internal combustion engine and a bearing of the crankshaft can move, a straight guide rail is utilized to set moving paths of the crankshaft and bearing, a screw drive mechanism is utilized to control the movement of the crankshaft and bearing of the crankshaft, thereby capable of continuously changing the compression ratio of the internal combustion engine. A matched spline output method for solving the problem of power output of the movement of the crankshaft is applied to adjust the design and manufacture of other subsidiary mechanisms of the internal combustion engine to adapt to the movement of the crankshaft and bearing of the crankshaft, thereby being capable of forming the complete and feasible internal combustion engine of the spline output of the variable compression ratio.
