Volvo’s new momentum

Koln, 25. April 2013 – While it always rehearsed again, you konnen the whole F1 circus for energy-saving tightening, because the technology transfer from racing is only a seemed attempt, Volvo reports, you have found in a comprehensive test series 2012 that flywheel Memory can be a cost-effective, lightweight and environmentally friendly method for consumption reduction in the strain traffic.

Flywheel? In a special form of Kers (Kinetic Energy Recovery System), as it is used since 2009 in Formula 1, a flywheel can be set to 64 during braking operation.000 / min accelerated to use the saved energy later. The Volvo people use a stepless transmission. You write: "As soon as the vehicle returns or accelerates, the rotating flywheel leads the stored energy to the rear ratchet. The internal combustion engine, which transfers its force to the front wheel, is switched off during the braking operation."

The NEFZ firmly in view

"Combined with a turbo four-cylinder, the flywheel technology can reduce fuel consumption by up to 25 percent towards a comparable six-cylinder turbomotor", explains Derek Crabb, Vice President Powertrain Engineering at the Volvo Car Group. "Due to the short-term provision of 80 additional PS, the four-cylinder also accelerates as well as a six-cylinder. The energy of the flywheel drives the vehicle alone for a short time. This has a massive influence on fuel consumption. According to our calculations, the internal combustion engine in the new European driving cycle (NEFZ) is switched off the half of the time", completed Crabb.
