The invention relates to a core design of a two-stroke internal-combustion engine with a shared combustion chamber. The shared combustion chamber is arranged in the middle of cylinders; an air inlet and an air outlet are respectively arranged at the two sides of the combustion chamber; the two sides of the combustion chamber can be considered as two cylinders which are internally provided with a piston respectively used for heat work conversion. When air change is carried out, as one end is only provided with the air inlet while the other end is only provided with the air outlet, new air drives out waste air in a shape of a 'horizontal line' during the whole air change process, thus changing the 'U'-shaped roundabout manner of air intake and exhaust in the past into a 'horizontal line' shaped through-flow manner of air intake and exhaust. The 'horizontal line' shaped air flowing manner is better than the 'U'-shape round-about manner of air intake and exhaust no matter for the spatial morphological characters
