A start control apparatus for an internal combustion engine includes first and second control mechanisms which are individually arranged to vary at least one of a compression ratio and an expansion ratio of a cylinder of the internal combustion engine. The start control apparatus measures a state of the internal combustion engine before cranking the internal combustion engine, wherein the state includes a state of the second control mechanism; sets a first control signal in accordance with the measured state of the internal combustion engine; and outputs the set first control signal to the first control mechanism before cranking the internal combustion engine.
