The invention relates to a centrifugal type impeller engine. The centrifugal type impeller engine comprises a combustion chamber and a spark plug. The centrifugal type impeller engine is characterized in that the combustion chamber is barrel-shaped; a cylindrical drive rotor is arranged in the combustion chamber; a first rotary shaft is arranged on the shaft center of the drive rotor; a groove is formed in the drive rotor; a drive rotary vane is arranged in the groove in a matched manner; the drive rotor has a first tangency point with the inner wall of the combustion chamber; the combustion chamber is equipped with a gas exhaust port; the gas exhaust port is positioned in one side of the first tangency point; the combustion chamber communicates with a high-pressure pipeline; an access point of the high-pressure pipeline is positioned at the other side of the first tangency point; and an ignition part of the spark plug is arranged on the communication part of the combustion chamber and the high-pressure pipeline. The centrifugal type impeller engine provided by the invention has the advantages of being small in vibration, low in noise, sufficient in combustion and the like.
