U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. The extent of fuel-air mixing can be affected by injection system design. Credit: ACS, Zimmerman et al.

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

One of the many emerging possible technology pathways to achieve those goals is the use of a future high-octane fuel in optimized, higher-compression-ratio engines. The study by the Ford / AVL team provides an overview of the effects of such a future ethanol-gasoline blend in such an engine. (As and of gasoline, about 14.6

Daimler launches diesel plan; expands recall to >3M units, accelerating next-gen diesel launch

Green Car Congress

The new OM 654 for the E-Class delivers around 13% lower fuel consumption and CO2 emissions along with a further increase in output (143 kW instead of 125 kW) compared to its predecessor, the OM 651. In addition to the advantages in terms of emissions, this results in fuel savings, especially on short journeys.
