FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio. Range of the variation of the length of the conrod is dependent on the required minimum and maximum compression ratio as well as the stroke.

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

With this move, Valeo becomes the first automotive supplier to offer its customers a range of electric superchargers. Highly efficient at low engine revolutions, electric superchargers make it possible to downsize engines. version of the vehicle but with fuel economy and CO 2 emissions approaching those of a Prius.

Magnetic eCVT could replace conventional hybrid mechanical eCVT with likely 1-2% fuel economy improvement and other benefits

Green Car Congress

By controlling the current flow through the stator control windings the rotational speed of the PM control rotor is varied and hence the gear ratio can be controlled over a broad range about the intrinsic ratio. The gear ratio can range from 1:1 to 1:15, Kirby said. The gear ratio can range from 1:1 to 1:15, Kirby said.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

Ford engineers also presented two other papers evaluating the effects of low to mid-level ethanol blends in spark-ignited engines at the conference. As a result, as the ethanol content of the fuel is increased, the fuel economy and driving range for a given fuel tank size are reduced. Downsizing/downspeeding.
