Patent number: 7225769Abstract: This invention concerns a two-stroke cycle engine, more specially it concerns a two-stroke cycle engine using a preceding air-layer for scavenging. It has a scavenger passage connected to a branching scavenger passage opened to said scavenging port. The engine has a connecting passage to link the air passage and the fuel passages so that negative pressure in the air passage forces the fuel-air mixture in the fuel passage into said air passage. Further, the engine according to this invention has a removable guide with a surface forming a curved smooth channel which is attachable to the scavenger passage in the crankcase from the mounting surface, and forms a portion of said scavenger passage with the curved channel. The blow-up angle of the scavenger passage varies along the circumferential direction of the cylinder.Type: GrantFiled: August 6, 2003Date of Patent: June 5, 2007Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Kazuyuki Uenoyama, Yoshio Kobayashi, Kazunori Kudou
