Abstract
A system and method for starting an engine having a crankshaft is provided. Pressurized fluid is stored in an accumulator. A flow of pressurized fluid is released from the accumulator. The flow of pressurized fluid released from the accumulator is directed to a pump that is operatively engaged with the crankshaft of the engine. The flow of pressurized fluid drives the pump to generate a rotation of the crankshaft and thereby start the engine.
