An air hybrid vehicle is described powered by an internal combustion engine 16 which may or may not be equipped with a supercharger or turbocharger 10 for boosting the engine 16. In the invention, power is taken from the vehicle to drive the engine 16 during deceleration or coasting of the vehicle. The engine 16 absorbs energy from the vehicle and produces boost air which is transferred and stored in the pressure range of the typical engine 16 boost pressure in a separate boost air storage tank in the vehicle and this boost air is immediately suitable and ready for use for boosting the engine 16 during acceleration or cruising of the vehicle. The vehicle achieves fuel saving and high performance by boost substitution when this boost air is used to supply the engine 16, temporarily fulfilling the role of an air charger without actually driving an air charger by substituting the boost normally supplied by an air charger 10 with an equivalent boost produced and stored during regenerative braking. To accommodate a large boost air storage tank, the body of the vehicle is adapted with air-tight volumes 34, 34a, 34b linked together including the trunk of the vehicle serving both as a general luggage space and a very large boost pressure air storage volume as soon as the trunk is closed. |
