PROBLEM TO BE SOLVED: To provide a cylinder injection control device improving an engine output, preventing generation of smoke and improving exhaust emission and fuel consumption. SOLUTION: In a cylinder injection control device of a cylinder injection engine controlling fuel injection timing by a crank angle, a piston upper surface center part is substantially flat, an injection inhibiting range K is provided within intake stroke after a top dead center and fuel is injected at two stages A, B before and behind this injection inhibiting range K when a crank angle range of a required fuel injection becomes a prescribed angle or more.
