Abstract
A lubrication control system includes an accumulator to store oil. The accumulator can be filled with oil during operation of an engine. A control valve can be selectively operated to allow oil stored in the accumulator to flow to a turbocharger. At least one control module can control operation of a hybrid electric vehicle and determine an operating condition of the engine and command the control valve to open and close based on the operating condition.
