SYSTEMS FOR PREVENTING ENGINE BEARING DAMAGE

A system for protecting an engine (132, 202) from damage due to vibration while the engine (132, 202) is not operating is provided. The system includes an engine (132, 202) having a crankshaft (204), at least one piston (206), at least one bearing (210), a lubricating fluid source (212), and a fluid pump (216) associated therewith and a controller (228) operationally connected to and configured to control the fluid pump (216). When the system is in a first mode, the controller (228) is configured to control the fluid pump (216) in a duty cycle to maintain a predetermined minimum fluid pressure of the lubricating fluid such that a lubricating fluid film is present between the at least one bearing (210) and the crankshaft (204) while the engine (132, 202) is not operating.
