Swedish car brand Volvo to develop flywheel system kinetic energy recovery (KERS Flywheel) can help reduce fuel consumption by 25%.
Flywheel Flywheel mounted on the rear of the vehicle, such as brakes during stop at the intersection when the red lights, brake energy to rotate the flywheel to 60,000 rpm / min. As the car rolled back, the rotation of the flywheel power is transmitted to the rear wheels through a special actuator. (Watch video below).
Volvo's solution is highly appreciated because of the internal combustion engine (ICE) vehicle is interrupted as soon as the driver hit the brakes, so that the kinetic energy of the flywheel is retained until the vehicle rolled. Volvo said flywheel KERS system works most effectively when operating in urban areas are more crowded intersection point.
Besides flywheel systems can also help increase performance, Volvo says the system has been tested on the S60 sedan, and the car can accelerate from 0-100 km / h in 5.5 seconds however, the Swedish automaker has not said internal combustion engine capacity of the vehicle.
Volvo has developed the technology "push flywheel support" in the 1980s, and first introduced the Model 260. However, due to iron flywheels can be too heavy to operate efficiently, so the project was put aside.
Nowadays, with the development of new materials, KERS flywheel is made from carbon fiber, weighs only 6 kg with a diameter of 20 cm.
