Diesel-Electric Hybrid Bus Uses Regenerative Brakes to Increase Efficiency and Economy
Daimler receives additional orders for its hybrid diesel-electric buses from New York City's transit authority. The hybrid vehicles have a number of technological advancements, from its propulsion system to the brake system. ...
... "To further boost efficiency, the vehicle has a regenerative braking system that uses the drive motor to slow the bus, effectively turning the motor into a generator that produces additional current to charge the energy storage system. The feature also reduces brake wear, reducing the need for brake maintenance. Compared to standard diesel propulsion, these hybrid buses deliver up to 30 percent better fuel economy while greatly reducing emissions: 90 percent less particulate matter, 40 percent less NOx and 30 percent fewer greenhouse gases. Drivers and riders enjoy a quieter, cleaner and smoother ride. " ...Via Daimler: Orders for Next Generation Diesel-Electric Hybrid Buses
