PROBLEM TO BE SOLVED: To achieve relatively good stratified charge combustion even when inner cylinder temperature is low by a control device for a cylinder injection spark ignition internal combustion engine that facilitates forming of a mass of combustible gas mixture inside a cavity formed on the piston top surface in the latter half of the compression process by injecting fuel inside the cavity and making inside of the cavity a stagnation space using the air intake flow turning inside the cylinder. SOLUTION: This control device comprises a variable means 9 that can vary strength of the air intake flow, and when the piston temperature is below a predetermined temperature, strength of the air intake flow is weakened by the variable means.
