Patent number: 10662870Abstract: A variable geometry turbine having a wastegate includes a turbine housing, a power turbine, and a regulating valve. The turbine housing is provided with an inner intake gas flow channel and an outer intake gas flow channel. The turbine housing is further provided with a wastegate pipeline configured to bypass the power turbine, and a wastegate valve configured to control communication of the wastegate pipeline. One of the regulating valve and the wastegate valve has a regulating face having a varying axial height in a rotation direction of the regulating valve, and the other of the regulating valve and the wastegate valve has a linking portion which makes contact and cooperates with the regulating face. Thus, the efficiency of the turbine is improved significantly and backflow of the gas flow is reduced.Type: GrantFiled: August 4, 2015Date of Patent: May 26, 2020Assignee: KANGYUE TECHNOLOGY CO., LTD.Inventors: Hang Wang, Wuhai Sang, Daojun Yuan, Lihua Song, Xiaofen Xin, Wei Li

Patent number: 9494111Abstract: A variable geometry turbine for turbochargers in exhaust gas recirculation engines incorporates a turbine housing having an exhaust inlet with a first side receiving exhaust from cylinders having exhaust gas recirculation (EGR) and a second side receiving exhaust from non-EGR cylinders. The first side has a first EGR-driving passage and a second EGR-driving passage and the second side having a first non-EGR-driving passage and a second non-EGR-driving passage. A first control valve is associated with the second EGR-driving passage and a second control valve is associated with the second non-EGR-driving passage. A controller is adapted to control the first and second control valves.Type: GrantFiled: July 2, 2014Date of Patent: November 15, 2016Assignee: KANGYUE TECHNOLOGY CO., LTDInventors: Wang Hang, Steven Don Arnold, Yuan Daojun, Li Yanzhao, Sang Wuhai

Patent number: 9249719Abstract: A turbine device, including: a turbine housing including an inlet, a flow channel, an outlet, a middle partition, an arced partition; a turbine impeller; a gas outlet; and an exhaust manifold. The turbine impeller and the gas outlet are arranged inside the turbine housing. The exhaust manifold is connected to the inlet. The flow channel is arranged inside the turbine housing. The outlet is arranged on the flow channel close to the turbine impeller. The middle partition is disposed inside the flow channel and divides the flow channel into a left flow channel and a right flow channel. The arced partition is arranged in both the left and right flow channels. One end of the arced partition is in a rigid connection with the middle partition, and the other end of the arced partition is close to the outlet of the turbine housing.Type: GrantFiled: February 3, 2013Date of Patent: February 2, 2016Assignee: KANGYUE TECHNOLOGY CO., LTD.Inventors: Hang Wang, Chao Ma, Zhifu Zhu, Yongtai Li, Congcong Wang, Lihua Song, Xilu Guo

Patent number: 8480360Abstract: A turbocharger turbine having a double-layer flow passage and a variable cross-section, including a turbine housing, a volute diffuser channel, a power turbine, a volute gas feeding passage, and a partition wall. The volute gas feeding passage is arranged in the turbine housing. The partition wall is arranged in the volute gas feeding passage and divides the volute gas feeding passage into an external volute gas feeding passage and an internal volute gas feeding passage. The external volute gas feeding passage is located outside the internal volute gas feeding passage. The combination of the external and internal volute gas feeding passages forms different flow areas, sufficiently utilizing the waste gas energy of engines in a segmented mode. The variable cross-section turbine has a simple structure, is easy to upgrade at low cost, and can be easily mass-manufactured.Type: GrantFiled: December 31, 2011Date of Patent: July 9, 2013Assignee: Kangyue Technology Co., Ltd.Inventors: Hang Wang, Yanzhao Li, Xilu Guo, Hengxing Yang, Lunhai Guo
