Abstract: A control system for generating a modified torque command for a rotating electrical machine in a battery electric vehicle (BEV) includes a microprocessor, capable of reading executable commands stored in non-volatile memory, configured to electrically connect to an inverter, determine a rated maximum current of the rotating electrical machine, receive sensor input indicating a temperature or estimating the temperature of at least one portion of the BEV, output a modified maximum current based on the received sensor input, and generate a torque command to the rotating electrical machine based on the modified maximum current.

Abstract: A turbocharger bearing housing is disclosed. The turbocharger bearing housing comprises a main body extending radially outwardly forming a turbine end. The turbine end is formed having a complementary geometry with a turbine wheel. A passage is formed extending through the bearing housing to allow fluid communication with the exterior of the bearing housing.

Abstract: A control valve assembly of a variable cam timing phaser of a variable cam timing system, with the variable cam timing phaser including a housing and a rotor, and with the variable cam timing system including a camshaft, includes a valve housing extending along an axis. The valve housing includes a threaded portion adapted to engage the camshaft, and a body portion spaced axially from the threaded portion. The body portion defines a body interior. The control valve assembly also includes a piston disposed in the body interior and moveable along the axis between a first position and a second position. The control valve assembly further includes a cap removably coupled to the body portion of the valve housing. The cap includes a torque driving element configured to be received by a tool for transmitting torque from the tool for fixing the cap to the body portion.

Abstract: The disclosure relates to a disk (38) for a disk clutch (26) comprising an annular base element (76) which has a toothing (78) with multiple teeth (80) for achieving a rotary driving engagement with a disk carrier (34), wherein the base element (76) has at least one hardened region (96) in which the base element (76) is designed as harder than in the tooth flank regions (98, 100) of the teeth (80). In addition, the disclosure relates to a disk clutch (26) with such a disk (38), a double clutch device (2) with such a disk clutch (26), and a method for producing such a disk (38).

Abstract: A transmission mechanism with a pair of selectively engageable clutch systems is disclosed that has an upstream gear ratio and a downstream gear ratio that combine to provide an effective gear ratio. A different clutch drive member is associated with an input side of each of the pair of clutch systems. The clutch drive members are driven for rotation by an engine input member. The upstream gear ratio is determined by the gear ratio between the engine input member and one of the clutch drive members. Output sides of each of the clutch systems drive an associated one of a pair of non-coaxial layshafts. Pinions are located on and selectively driven by the layshafts. A countershaft is spaced from both of the layshafts, and has a plurality of gears. Each of the gears is driven for rotation by one of the pinions of the layshafts. The downstream gear ratio is determined by the gear ratio between the selected pinion and the intermeshed gear.

Abstract: A method of adjusting an external exhaust gas recirculation mixture in response to engine knock of a spark-ignition turbocharged engine, and related products.

Abstract: A synergistic blade and hub structure for a cooling fan. Helical gussets are provided which proceed from the central hub member adjacent one blade member to the trailing edge of an adjacent blade member. The helical gussets provide structural load paths as well as aerodynamic flow guides. The helical gussets extend axially rearwardly to the trailing edges of preceding blade members and provide structural attachments between the leading and trailing edges of adjacent blade members. Hollow triangular structures are also provided on the rear of the fan structure and the triangulation area provides superior stiffness.
