    • A stratified scavenging two-cycle engine is capable of doing away with emission of a mixture into the atmosphere and of reducing intake resistance of air. For this purpose, an air intake port (11) is provided at a position which is a predetermined distance away from scavenging ports (51) toward a crank chamber (20) parallel to the axial direction of the cylinder block (1), and the scavenging ports (51) are connected to the air intake port (11) through a piston (3) to thereby supply air to scavenging flow passages (50) from the air intake port (11) through the scavenging ports (51) at the time of an intake stroke.
    • 分层清扫双循环发动机能够消除大气中的混合物的排放并降低空气的进气阻力。 为此,在与扫气口(51)相对于与气缸体(1)的轴向平行的曲柄室(20)的预定距离的位置处设置有吸气口(11), 清扫口(51)通过活塞(3)与吸气口(11)连接,从而从空气吸入口(11)通过扫气口(51)向空气流通道(50)供给空气 的进气冲程。
