22. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction
Sammanfattning : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. LÄS MER
