Navigant forecasts global road transportation energy consumption to increase 25% by 2035; 84% from conventional fuels

Green Car Congress

Navigant also projects that investments in alternative fuel and fuel efficiency improvements will reduce annual energy consumption in the United States year-over-year. The alternative fuels market share will grow from roughly 7.4% quadrillion Btu projected to be consumed in 2014.

This is also an advantage because cooling systems can be downsized or removed altogether. Having investigated power issues arising from conventional and alternative fuels, he looked in great depth at onboard hydrogen storage issues and fuel cell development for the automotive industry.

FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

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.

New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process

Green Car Congress

The new coating also was developed to help meet requirements for new production engines planned for 2018-2020, which call for less cylinder-bore friction and the use of lower-viscosity oils and alternative fuels. It provides the superior performance of a more costly premium inlaid top ring. Typically high-output engines under 3.5

Split injection Miller cycle with boost decreases knock tendency and increases torque in downsized engine

Green Car Congress

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. Their paper is published in the journal Fuel. 2017.11.006.
