Buick offering 2.0L direct-injection turbo option for 2013 Verano

Green Car Congress

turbocharged engine with direct injection and continuously variable valve timing that produces an SAE-certified 250 horsepower (187 kW) at 5300 rpm and 260 lb-ft (353 Nm) of torque at 2000 rpm. Fuel economy numbers are not final, but the Verano Turbo is expected to be in line with Buickā€™s other turbocharged models.

Rare Rides Icons: The Lincoln Mark Series Cars, Feeling Continental (Part XLIII)

The Truth About Cars

Other dimensions of the Mark VIII were larger in all directions, a stark contrast to the extreme downsizing implemented on Mark VI, a measure pushed further by the tidy proportions of the Mark VII.& For the first time ever, a Mark would debut with an engine not offered in other Ford or Lincoln products. & Mark VIII spanned 206.9

DOE awards Envera $2.8M to develop and to test efficient variable compression ratio engine

Green Car Congress

All three engine BSFC curves correspond to an engine speed of 2000 rpm.Click to enlarge. The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Envera specializes in the development of advanced technologies for improving automotive fuel economy.

Delphi develops new high-pressure common rail systems for heavy-duty and light-duty engines; Euro VI and beyond

Green Car Congress

This concept system is expected to be ideal for heavily downsized applications and developing markets. DPCRS technology is suited for engines currently using Electronic Unit Injector (EUI) systems or Electronic Unit Pump (EUP) systems because the installation envelope is the same as that for Delphiā€™s current products.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

However, most life cycle analyses (LCAs) to date have mainly focused on the production stage while assuming end-use efficiencies are the same for ethanol and gasoline despite the fact that ethanol can, in theory, affect engine efficiency and performance due to different thermo-chemical properties compared to gasoline. Policy implications.

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. bar was measured at 2000 rpm, with 17.4 Earlier post.)
