Abstract: A disconnect clutch comprises a passive centrifugal valve that is utilized to disconnect parasitic loads from an engine during the initial start-up and to automatically connect the parasitic loads once the engine speed is sufficient. The passive centrifugal valve operates dependent on a rotational speed of a flywheel assembly of the clutch and is configured to switch at a threshold rotational speed of the flywheel assembly.

Abstract: A power system comprising an engine that produces exhaust, a fuel system that injects a fuel into the engine, an aftertreatment system that treats the exhaust, and is controller. The aftertreatment system includes an oxidation catalyst that converts NO from the engine into NO2, a particulate filter that traps soot from the engine, and a sensor that provides an indication of the amount of soot in the particulate filter. The controller increases an engine fuel injection pressure when the amount of soot in the particulate filter is above a threshold.
