Study finds tailor-made fuels from biomass could significantly reduce emissions of criteria pollutants and greenhouse gases

Green Car Congress

All fuels were analyzed in four load points, three of which are within the NEDC range for an inertia weight class of 1590 kg, the fourth being of interest for future downsizing concepts. Optimized fuel properties with regard to different emissions Janssen et al. Click to enlarge. Click to enlarge.

Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power. Earlier post.) Fabien Redon.

Fiat to Preview Turbo Two-Cylinder Twin-Air at Geneva Show; Natural Gas and Hybrid Applications to Come

Green Car Congress

The new Twin-Air engine is an example of downsizing: combining a small displacement engine with a next-generation turbocharger to provide performance comparable to—or better than—that of a larger engine but with less fuel consumption and lower emissions.

Renault Launching New 2.3L Diesel

Green Car Congress

Renault is thus pursuing its downsizing strategy of reducing engine displacement—and, hence, CO 2 emissions and fuel consumption—while maintaining performance. It will meet two pollution standards: Euro4 (without a DPF) and Euro5 (with a DPF). The new engine offers reduced fuel consumption (by 1 liter/100 km on average and by up to 2.7

Ford Making Aggressive Push With EcoBoost and Technologies Such as Ti-VCT for Improved Fuel Economy; Roadmap for Future Generations of EcoBoost Highlights Role as Company Strategy as Well as Product

Green Car Congress

The more efficient combustion engine technologies, with their enabling of downsizing, come in compatibly with hybridization, with hybridization and electrification playing a larger role over time. The further downsized next-generation technologies can be very synergistic within hybrid applications. Planning background.
