Abstract
An engine having a fluid lubrication and control system is provided. The engine also includes a pump configured to maintain fluid pressure in the lubrication and control system when the engine is running. The engine additionally includes an accumulator in fluid communication with the lubrication and control system. The accumulator is configured to accumulate and retain fluid when the engine is running, and to discharge the fluid when the engine is not running in order to maintain fluid pressure in the lubrication and control system. A method for controlling oil pressure in the engine is also provided.
