摘要： It is intended to provide a two-cycle internal combustion engine capable of preventing the blow-by phenomenon, thereby improving both fuel economy and exhaust purifying performance, and superior in the responsivity of fuel injection volume.
[Means for Attaining the Subject] In a two-cycle internal combustion engine wherein a chamber 29 is disposed in scaventing passages 14,15 which provide communication between a crank chamber 9 and a combustion chamber 6, sealable control valves 26 and 33 are disposed in an inlet and an outlet, respectively, of the chamber 29, and a fuel feeding system 37 for the supply of fuel into the chamber 29 is provided, the present invention is characterized in that the chamber 29 is brought into communication with one scavenging passage 18 out of a plurality of prallel scavenging passages, and the control valve 33 disposed in the chamber outlet, which is on the combustion chamber side and on a scavenging downstream side, is positioned at the bottom part of the scavenging passage 18 communicating with the chamber 31 with respect to the control valve 26 disposed in the chamber inlet which is on the crank chamber side.摘要翻译： 旨在提供能够防止窜气现象的双循环内燃机，从而提高燃料经济性和排气净化性能，并且燃料喷射量的响应性优异。 Ä获得主体的方法在一个双循环内燃机中，其中腔29布置在提供曲柄室9和燃烧室6之间连通的扫气通道14,15中，可密封的控制阀26和33设置在入口 并且分别设置有腔室29的出口和用于将燃料供应到腔室29中的燃料供给系统37，其特征在于，腔室29与一个扫气通道18连通， 多个平行清扫通道，并且设置在室出口中的在燃烧室侧和扫气下游侧的控制阀33位于与腔室31连通的扫气通道18的底部， 到设置在曲轴室侧的室入口中的控制阀26。
