Abstract: No numbers found in figures. An example vehicular shock absorbing apparatus includes a shock absorber, a hydraulic mount operatively coupled with the shock absorber, a first decoupler movably disposed in a first portion of the hydraulic mount, and a second decoupler movably disposed in a second portion of the hydraulic mount.

Abstract: A hydraulic mount for a vehicle shock absorber includes a first housing portion, a second housing portion, an orifice plate and a diaphragm connected together to define a first chamber and a second chamber in the hydraulic mount. A first resilient member disposed on the orifice plate defines a first sub-chamber in the first chamber and a second resilient member disposed on the orifice plate defines a second sub-chamber in the second chamber.

Abstract: Various methods for compensating variation in the geometry and position of linkages and valve seats in wastegate assemblies are provided. In one example, a method of operating a wastegate in an internal combustion engine comprises, at engine startup, placing a wastegate valve at a seat, recording a position of the seat and associating the seat position with one or more operating parameters, and modifying a position of a wastegate actuator based on the seat position throughout engine operation.

Abstract: Methods and systems are described for an oil delivery system of an engine. In one method, oil is pumped via a lower pressure oil pump to piston cooling jets while oil is separately pumped via a higher pressure oil pump to a cylinder head, bearings, a turbocharger, or a variable valve operation system. Herein, the higher and lower pressure oil pumps each draw oil from a common, shared sump, and return oil back to the common, shared sump.

Abstract: Various methods for determining a holding current based on a pressure differential across a wastegate valve are provided. In one example, a method of operating a wastegate comprises determining a holding current with which to hold a wastegate valve at a desired position, the holding current determined based on a pressure differential across the wastegate valve.

Abstract: In one embodiment, a method for an engine comprises adjusting an engine operating parameter based on exhaust pressure, the exhaust pressure estimated based on wastegate actuator motor current.

Abstract: Various methods for controlling a wastegate with an actuator having a temperature-dependent magnetic field are provided. In one example, the magnetic field is estimated based on operating conditions and other parameters, and used to apply a magnetic correction to a voltage supplied to the actuator. The methods may provide accurate wastegate control in the presence of varying magnetic fields, ensuring the proper supply of boost to an engine.

Abstract: Various methods for determining the fully closed position of a wastegate valve are provided. In one example, a non-closed position command for a wastegate valve in a low-lift region relative to a valve seat is received. Prior to executing the position command, the wastegate valve is only temporarily closed to thereby determine a fully closed position.

Abstract: A system and method for operating an engine turbocharger is described. In one example, the turbocharger includes an electrically actuated waste gate. A controller adjusts a position of the electrically actuated waste gate.

Abstract: Various embodiments relating to detection of an end-stop position of a waste gate valve and calibration of a waste gate position sensor relative to the detected end-stop position are provided. In this way, it is possible to more accurately control the waste gate.

In one example, a method of operating a wastegate comprises determining a holding current with which to hold a wastegate valve at a desired position, the holding current determined based on a pressure differential across the wastegate valve.

Abstract: Various methods for controlling a wastegate with an electric actuator including a bias are provided. In one example, the actuator is supplied with a first current when moving a wastegate valve toward a fully open position, and is supplied with a second current when moving a wastegate toward a fully closed position. The methods may ensure appropriate supply of boost to an engine even in the event of wastegate degradation while enabling engine downsizing.

Abstract: Various methods for compensating a deflected linkage in a wastegate arrangement are provided. In one example, current is applied to an actuator to move a wastegate valve coupled through a linkage to the actuator for diverting gasses from a turbocharger. The position of the actuator is indicated, and a correction to said indicated actuator position is applied compensating for deflection of the linkage based at least on said applied current. Said applied current is adjusted when said corrected actuator position reaches a position corresponding to a desired valve position.
