An air hybrid vehicle is described powered by an internal combustion engine which may or may not be equipped with a supercharger or turbocharger for boosting the engine. In the invention, power is taken from the vehicle to drive the engine during deceleration or coasting of the vehicle. The engine absorbs kinetic energy from the vehicle and uses that energy to produceboost air which is transferred and stored in a boost air storage tank on board the vehicle at a storage pressure not exceeding 3 bar absolute pressure. The vehicle achieves fuel saving and high performance by boost substitution when this boost air is used to supply the enginefor short periods during acceleration or cruising of the vehicle without relying on any air charger, temporarily fulfilling the role of an air charger without actually driving an air charger by substituting the boost normally supplied by an air charger 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 linked together to form one large storage volume. |
