PURPOSE:To provide a combustion control device for a two-cycle engine which suppresses generation of carbon around a connection part between a detection passage and a cylinder wall, attains stable air-fuel ratio controlling, and avoids damage of a piston. CONSTITUTION:Cylinders having phase differences are communicated with each other. An edge of a combusted gas sampling port 65 of a communication passage 40 having an O2 sensor 35 which detects oxygen concentration of the combusted gas on the way thereof is chamfered at its side of a cylinder bore to form a guide portion. |
