  • Patent number: 10145426
    Abstract: A forward/reverse planetary gearset (412) may be adapted to employ multi-mode clutch modules (426, 430) in lieu of using only traditional friction clutches (326, 330). Such arrangement may reduce parasitic drag as well as achieve reductions in physical size of the gearset housing (408). Use of multi-mode clutch modules (426, 430) may offer either of or both forward and reverse controls of the planetary gearset (412). Thus, in at least one arrangement a multi-mode clutch (426) may provide forward clutch control while a friction clutch (330) provides reverse clutch control. In another arrangement the friction clutch (326) may provide the forward clutch control, while the multi-mode clutch (430) provides the reverse clutch control for the gearset (412). Finally, both forward and reverse controls of the gearset (412) may be provided via multi-mode clutches (426, 430), thus entirely avoiding use of any friction clutches (326, 330) for forward or reverse control functions of the planetary gearset (412).

  • Patent number: 10138744
    Abstract: A plurality of guide vanes (34) in a variable turbine geometry turbocharger (10) regulates a flow of exhaust gas. The guide vanes (34) are selectively adjustable between an open position to allow the flow of exhaust gas to drive a turbine wheel (24) and a closed position to block the flow of exhaust gas. A first flow feature (58) is disposed on first (44) and second (46) edges of the guide vanes (34) to disturb the flow of exhaust gas to prevent leakage of exhaust gas around the first (44) and second (46) edges. A second flow feature (64) is disposed on front (60) and rear (62) surfaces of the guide vanes (34) to channel the flow of exhaust gas between adjacent guide vanes (34) when the guide vanes (34) are in the open position to prevent swirling and/or cross flow of the exhaust gas.

  • Patent number: 10132324
    Abstract: To solve the problems of compressor wheel blade flow separation causing surge type noises when a compressor return or recirculation valve is opened or closed, recirculation airflow from a compressor recirculation valve is fed into an annular volume, defined between inner and outer walls or shaped as a radially expanded, axially flattened cylindrical space in the compressor inlet, so that the generally unidirectional radial flow from the compressor recirculation valve is re-directed and organized as it is turned from generally radial to generally axial, merging with the general inlet flow and presenting the compressor wheel with airflow of“circumferentially uniform” flow velocity.

  • Patent number: 10132230
    Abstract: A method of controlling exhaust gas recirculation (EGR) in a turbocharged compression-ignition engine system including an engine, an induction subsystem in upstream communication with the engine, an exhaust subsystem in downstream communication with the engine, a high pressure EGR path between the exhaust and induction subsystems upstream of a turbocharger turbine and downstream of a turbocharger compressor, and a low pressure EGR path between the exhaust and induction subsystems downstream of the turbocharger turbine and upstream of the turbocharger compressor. A target total EGR fraction for compliance with exhaust emissions criteria is determined, then a target HP/LP EGR ratio is determined to optimize other engine system criteria within the constraints of the determined target total EGR fraction.

  • Patent number: 10125699
    Abstract: A method, using multiple position sensors, for determining a characteristic of the actuator or a system, wherein the characteristic is causing or is indicative of the cause of the change in position of the actuator. One characteristic may be the lost motion of the actuator or system. Lost motion is the lag between the motion of a controlled device and that of an electrical drive device due to yielding or looseness. The lost motion of an actuator may increase as components wear and may eventually degrade the function or cause failure of the actuator and/or system.

  • Patent number: 10119461
    Abstract: A vehicle system including a plurality of alternators with a common electrical connection interface having at least one connector and a digital communication connector through which a processor communicates with the alternators. Input signals received at the at least one connector are unique for each alternator under normal and unimpaired operating conditions. Upon wakeup of an alternator, the alternator assesses the input signals and whether the address of the alternator is frozen. If the address is not frozen, the status of at least one operating parameter is assessed to determine if a predefined requirement is satisfied. If the predefined requirement is satisfied, the alternator is assigned an address based upon the input signals at the at least one connector and the address is frozen. The alternator can detect faults by determining if the input signals at the least one connector agree with the frozen address of the alternator.

  • Patent number: 10119431
    Abstract: A system (42) including a phaser (28), a motor (38), and a controller (40) for controlling the phase between a camshaft (18) and a crankshaft (16) of an engine (10). The phaser (28) is attached to the camshaft (18), is in communication with the crankshaft (16), and is configured to adjust the phase of the camshaft (18). The motor (38) actuates the phaser (28) and is operatively attached to and in communication with the phaser (28) such that rotation of the crankshaft (16) back-drives the motor (38) to subsequently generate a signal. The controller (40) is in electrical communication with the motor (38), is responsive to the signal, and uses the signal to determine the rotational speed of the motor (38) to thereby commutate the motor (38) and subsequently drive the motor (38) so as to actuate the phaser (28) and control the phase of the camshaft (18).
