Many improvements in fleet fuel economy in Europe have been achieved through increased diesel market share, with the diesel market share in Europe now above 50%. We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. Differentiated Analysis of Downsizing Concepts”).

While policies worldwide are tightening emissions and fuel economy standards, the strictest standard of all is expected in Europe in 2020, Bohr said—average fleet CO 2 emissions of 95 grams per kilometer. This reduces fuel consumption by about 5%. How can this be achieved technically?

The Freightliner SuperTruck uses a downsized and downsped 10.7-liter The Freightliner SuperTruck features a low-back-pressure, next-generation aftertreatment system that efficiently removes NO x from the exhaust stream. The aftertreatment system features additional insulation to retain maximum heat energy in the exhaust.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.

Dedicated ethanol (or E85) engines have the promise to improve efficiency substantially over comparable regular gasoline engines through direct-injection, increased geometric CR, variable valve timing, exhaust gas recirculation, aggressive turbocharging, and downsizing and/or downspeeding.

Focused on meeting a growing customer demand for ‘downsized’ engines offering strong power with reduced fuel consumption and CO2 emissions, the new gasoline and diesel powertrains are being progressively introduced across the Opel product range. The engine retains the proven concept of a turbine-integrated exhaust manifold.
