20-78 SISTEME DE PROPULSIE HIBRIDE SOLUŢIE DE UTILIZARE EFICIENTĂ A ENERGIEI DISPONIBILE PE AUTOVEHICULELE RUTIERE


HYBRID PROPULSION SYSTEMS AN EFFICENT
SOLUTION FOR ON –BOARD AUTO VEHICLE ENERGY
The paper summarizes the main solution for improving the motor
vehicle fuel economy. The analyzed solutions are: transmission efficiency
improvement, idle shut off, driving resistance improvement, load point
deflection, regenerative braking, and exhaust gases energy recovery.
The potential of each solution is then use to demonstrate the
advantages of hybrid propulsion systems. It is shown that, for a mild-hybrid
passenger car, it is possible to achieve a 16 to 28 % cumulate fuel economy
improvement.
