PROBLEM TO BE SOLVED: To provide an engine system including a boost assist device allowing economical use of energy.SOLUTION: According to one implementation of an engine system, a power device 48 is selectively actuated to provide energy to a storage device 46. Energy from the storage device is selectively provided to a boost assist device 14 to supplement the normal energy supply to a boost device 12 and enable an increased power output of the engine in at least certain engine 16 or vehicle operating conditions. In one form, the power device may be a source of electrical energy and the storage device is capable of storing an electrical charge. In another form, the power device is a fluid pump and the storage device is capable of storing pressurized fluid. Various methods may be employed to control operation of the power device and energy storage in the storage device. |
