Abstract: A camshaft assembly can control the motion of the intake or exhaust valves of an internal combustion engine and includes a base shaft extending along a longitudinal axis. The camshaft assembly further includes an axially movable structure mounted on the base shaft and axially movable relative to the base shaft. The axially movable structure includes a plurality of lobe packs. Each lobe pack includes a plurality of cam lobes. The axially movable structure includes a barrel cam defining a control groove. The camshaft assembly additionally includes an actuator including an actuator body and a pin movably coupled to the actuator body between a retracted position and an extended position. The axially movable structure can move axially relative to the base shaft when the base shaft rotates about the longitudinal axis and the pin is in the extended position and at least partially disposed in the control groove.

Abstract: A control system for a vehicle includes a target boost module and a turbocharger control module. The target boost module determines a target boost for first and second turbochargers based on an engine torque request. Based on a temperature of a compressor of the second turbocharger, the turbocharger control module: selectively opens a first bypass valve that regulates exhaust bypassing a first turbine of the first turbocharger; and selectively closes a cutoff valve that regulates exhaust flow through both a second turbine of the second turbocharger and a second bypass valve. The second bypass valve regulates exhaust bypassing the second turbine of the second turbocharger.

Abstract: An engine control system includes a mean effective pressure (MEP) module, an imbalance module, and a phaser control module. The MEP module determines MEPs for combustion cycles of cylinders, respectively, of an engine. The imbalance module selectively determines whether first and second banks of the cylinders are imbalanced based on the MEPs. When the first and second banks of cylinders are imbalanced, the phaser control module selectively adjusts at least one of: a first phaser of an intake camshaft of the second bank of cylinders; and a second phaser of an exhaust camshaft of the second bank of cylinders.
