    • PROBLEM TO BE SOLVED: To provide a reverse-flow type two-cycle engine capable of effectively suppressing the blowby of a fresh mixture (unburned air-fuel mixture) and further improving scavenging efficiency and burning efficiency. SOLUTION: Cross sectional shapes of at least a pair of scavenging passages (31 and 31, 32 and 32) are more similar to triangles than parallelograms which are narrowest at the cylinder outer peripheral side and wide at the cylinder bore wall surface (10a) side over the generally entire area in the longitudinal direction. Horizontal scavenging angles (α, β) which are cross hatch angles of extensions (Ea and Ea, Eb and Eb) of guide wall surfaces (31c and 31c, 32c and 32c) defining the scavenging passages (31 and 31, 32 and 32) to the suction port (33) side are acute-angled.

    • 解决的问题:提供能够有效地抑制新鲜混合物(未燃烧空气 - 燃料混合物)的窜流的逆流式双冲程发动机,并且进一步提高清除效率和燃烧效率。 解决方案:至少一对清扫通道(31和31,32和32)的横截面形状比在圆柱体外周侧最窄且在气缸孔壁表面处宽的平行四边形更类似于三角形( 10a)侧在整个纵向上的整个区域上。 定义扫气通道(31,31,32,32)的导向壁面(31c,31c,32c,32c)的延伸部(Ea,Ea,Eb,Eb)的交叉角度的横向扫视角(α,β) 到吸入口(33)侧是锐角的。 版权所有(C)2011,JPO&INPIT
