A method is provided for operating an air hybrid vehicle by boost substitution in a vehicle powered by an internal combustion engine 16 equipped with a rotary air charger 10 connected directly to the engine 16 while having selectable means for loading and unloading the air charger 10. The method comprises the steps of producing boost air using energy derived from braking of the vehicle at times when the engine 16 is driven by the vehicle during deceleration or coasting of the vehicle, delivering and storing the boost air in a separate air storage tank 34 in the vehicle, and controlling the rotary air charger 10 at times when the engine 16 is driving the vehicle during acceleration or cruising of the vehicle while air is supplied to the engine 16 for combustion in the engine 16 according to one of at least three selectable routes or modes including route a) naturally aspirated when boost is not required and the rotary air charger 10 is unloaded, route b) boost air is delivered from the air storage tank 34 to the engine 16 when boost is required and the rotary air charger 10 is unloaded, and route c) boost air is delivered from the rotary air charger 10 to the engine 16 when boost is required and the rotary air charger 10 is loaded, the vehicle achieving fuel saving and high performance by boost substitution in not driving the rotary air charger 10 in real time when the engine 16 is supplied with boost air according to route b) produced and stored earlier during deceleration or coasting of the vehicle. |
