Patent number: 10458319Abstract: A method of joining parts of the wastegate assembly, and a wastegate assembly includes an arm defining a hole. The wastegate assembly also includes a shaft. The shaft includes a first end disposed inside the hole of the arm. The shaft includes an outer surface defining a groove disposed inside the hole of the arm. The arm and the first end of the shaft are welded together to form a joint having a joint root region disposed adjacent to the groove. A turbocharger includes a compressor, a turbine and a rotating assembly driven by exhaust gas. The rotating assembly has a turbine wheel disposed inside the turbine and a compressor wheel disposed inside the compressor. The turbocharger further includes the wastegate assembly described above, and the wastegate assembly defines an opening configured to selectively redirect at least a portion of the exhaust gas to bypass the turbine wheel.Type: GrantFiled: June 1, 2017Date of Patent: October 29, 2019Assignee: GM Global Technology Operations LLCInventors: Grant W.

Patent number: 10458320Abstract: A wastegate actuator assembly includes a regulating rod, an arm, and a shaft. The regulating rod includes a proximate end region and a distal end region wherein the proximate end region of the regulating rod may be connected to an actuator. The arm includes a first end region and a second end region. The first end region is pivotally coupled to the distal end region of the regulating rod via a crank pin, a first cup spring, and a second cup spring wherein the first and second cup springs retain a solid lubricant substantially around the crank pin. The regulating rod may move in a linear fashion causing the arm and the shaft to rotate so as to move a wastegate cover connected to the shaft from a closed wastegate duct position (toward the wastegate duct) to an open wastegate duct position (away from the wastegate duct).Type: GrantFiled: November 9, 2017Date of Patent: October 29, 2019Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Zhe Li, Julie A.

Patent number: 4724810Abstract: A feedforward throttle adjustment for a closed loop idle speed control provides engine power output required to drive a variable power steering load while maintaining the engine idle speed in a desired range. The working pressure of the power steering system is detected, and the change in such pressure in the course of a steering maneuver is used to initiate an increase in the engine power output setting. The increase is determined in relation to the peak pressure change; it is implemented at a pedetermined rate, and is subject to interruption whenever the pressure change indicates that the steering maneuver has ended.Type: GrantFiled: February 13, 1987Date of Patent: February 16, 1988Assignee: General Motors CorporationInventors: David C.
