HyBoost demonstrator debuts at LCV2011; 50% by swept volume downsizing with low-cost electrification

Green Car Congress

In implementing this 50% downsizing by swept volume, the research team delivered zero degradation in driveability, performance or acceleration. Earlier post.). The HyBoost concept is based on a 2009 Ford Focus in which a 2.0L naturally aspirated four-cylinder gasoline engine has been replaced with a 1.0L three-cylinder EcoBoost engine.

SwRI simulations show turbocharged Scuderi Engine could reduce a standard 2011 Nissan Sentras fuel consumption by up to 35% on FTP cycle

Green Car Congress

Modelled results of fuel consumption in 2011 Nissan Sentra. At the onset of the study, a computer baseline model of the Sentra was established, which closely matched the measured performance of the actual 2011 Nissan Sentra. Source: Scuderi. Click to enlarge. Preliminary results showed up to a 25% decrease in fuel consumption (i.e.,

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor. Highly efficient at low engine revolutions, electric superchargers make it possible to downsize engines. With this move, Valeo becomes the first automotive supplier to offer its customers a range of electric superchargers.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The share of diesel vehicles among new car registrations in the EU decreased from a peak of 55% in 2011 to 49% in 2016; recent data suggests that diesel shares continue to fall. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.
