Performance simulations of a low–cost hybrid powertrain with large fuel savings

This paper presents a new design of a low–cost mechanical hybrid powertrain with large fuel savings. The hybrid powertrain contains only low–cost mechanical components, such as a compact flywheel module and a Continuously Variable Transmission (CVT). No electrical motor/generator or battery is used. On the basis of the characteristics of typical driving cycles, the energy storage capacity of the flywheel module is derived accordingly. The fuel–saving potential of the new powertrain is simulated for a compact passenger vehicle, which represents the aimed vehicle segment in emerging markets. Simulations show that the fuel–saving potential, with respect to the same vehicle without flywheel module, ranges in between 15% and 29%, depending on the considered driving cycle.
