A procedure for startup and shutdown of an internal combustion engine with an electronically-controlled turbocharger (ECT) is disclosed. The startup and shutdown procedures are determined to provide the desired lubrication to engine and ECT components and sufficient cooling of the engine and ECT. In one embodiment, the system includes an electric oil pump that can supply oil to the oil circuit in the engine and ECT independently of an engine-driven mechanical oil pump. In another embodiment, the oil circuit is provided with an oil accumulator to provide oil for cooling after engine rotation has stopped. |
