ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

The company presented its first results at the annual ASME ICEF (Internal Combustion Engine Fall) conference in Chicago. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

Ford engineers also presented two other papers evaluating the effects of low to mid-level ethanol blends in spark-ignited engines at the conference. Downsizing/downspeeding. This increase in BMEP can enable downsizing of the engine displacement and/or downspeeding through revised gear ratios, findal drive ratio, or shift scheduling.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. At SC conditions, however (T?450
