Mazda to use regen brakes to boost fuel economy 5 to 10 percent

Autoweek Magazine -- Mazda is adding a fuel-saving technology that harnesses wasted brake energy in the redesigned Mazda6 sedan due early next year.

The approach uses regenerative braking to convert kinetic energy into electricity that is stored in a capacitor. The car later taps that capacitor to power the fuel pump, lights, audio, air conditioning and transmission and engine control systems.

Traditionally, power for those functions is drawn from the engine.

But Mazda's innovation, called i-Eloop, relieves the engine of those duties, allowing it to channel its output more efficiently.

The technology will boost fuel economy "by 5 percent to 10 percent," Seita Kanai, executive vice president in charge of r&d, said during a press event in Japan.

The regenerative braking capacitors will debut in the next-gen

tomok Champion Author Portland Posts:33,039 Points:2,346,485 Joined:Aug 2006	Message Posted: Jul 12, 2012 8:09:20 AM Ignore tomok Report Abuse Instead of waste heat from braking, use that kinetic energy to produce power for the vehicle. Store the power, in the form of electricity, in batteries or capacitors for later use. Friction braking is still required at slow speeds or when the regen braking fails. Boost fuel economy 5 to 10 percent? That remains to be seen! Whatever the size or shape of the vehicle, Produce and ‘Drive’ vehicles with high MPG, are very safe, reliable, have a ‘reasonable’ cost and a good ‘value’ for the money. Consider using other forms of less expensive transportation to lower your cost. The price of fuel at the pump is too high! 12/22/2012!
