2009 Downsizing Fuel Economy Oil 
Green Car Congress
APRIL 22, 2013
Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

These tests resulted in the combined 115% freight efficiency improvement over a 2009 baseline truck. The Freightliner SuperTruck uses a downsized and downsped 10.7-liter Friction-reducing measures include a variable speed water pump, a clutched air compressor, low-viscosity oil and an improved cylinder kit. mpg (19.26

First introduced in the 2009 CC, the EA888 continued Volkswagen’s move toward smaller, turbocharged engines that offer the fuel economy benefits of downsizing with the power of a larger-displacement unit. Audi engineers described the development of the Gen3B at the Vienna Motor Symposium in 2015. Earlier post.)

The work of the consortium will be structured into a series of modules, the first of which will focus on the effect of downsized light duty gasoline and diesel engine technologies on lubricant soot levels and engine wear. Tags: Fuel Efficiency Lubricating Oils.

The global energy supply became 6% cleaner from 1971 to 1990,in response to the oil shocks of the 1970s. While fuel economy of engined-cars is the key technology pathway to decarbonizing the transport sector by 2020, the 2DS also envisages 20 million EVs on the road by 2020, with yearly sales reaching seven million vehicles.

The SuperTruck program was a five-year DOE research and development initiative to improve freight efficiency—meaning more payload carried while burning less fuel—by 50% compared to 2009 base model trucks. This new design added “wave” bumps on the side of the piston bowl, which allows the fuel to burn more cleanly.).
