Patent number: 10502129Abstract: A dual-crankshaft engine includes a piston and two crankshafts constituting a double-crank mechanism, and further includes a cylindrical block. The cylindrical block includes a cylinder portion and a crankshaft support portion. A lower end of the piston is a piston guiding rod. A piston rod guiding groove is provided in the cylindrical block. A lower end of the piston is opened, and provided with a piston end cover. The piston end cover and the piston guiding rod are detachably and fixedly connected. The piston is a non-skirted piston where the piston sealing end is separated from the piston guiding end. The piston sealing end is the piston head of the piston. The piston guiding end is the piston guiding rod and the piston rod guiding groove. The piston is designed to be equi-stress, which increases the strength.Type: GrantFiled: June 16, 2017Date of Patent: December 10, 2019Assignee: XUZHOU XIAN BO ENGINE MACHINERY TECHNOLOGY CO., LTD.Inventors: Pengbo Wang, Ping Wang, Yinping Liu
