Abstract
A method of operating an engine includes starting and stopping operation of an internal combustion engine that includes a crankshaft having a bearing journal and a bearing in which the bearing journal is rotatable. The crankshaft is constantly turned when the internal combustion engine is in the non-fueled mode. An oil pump can be driven to lubricate the bearing journal and the bearing while the internal combustion engine is in the non-fueled mode to provide hydrodynamic lubrication. An engine is also disclosed.
