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. Hybrid electric vehicles could especially benefit from this new technology, since the rapid engine warm up and high efficiency cycle that ECONAMIQ offers uses less fuel during power-assisted operation or battery charging.

CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.

CPT VTES Electric Supercharger Selected for Two Projects

Green Car Congress

When applied to a radically downsized 1.2-liter liter naturally aspirated engine, the downsized engine with electric supercharger reduces the 70-100 km/h (44-63 mph) top gear acceleration time from 18 to 11 seconds. CPT will showcase VTES at the international supercharging conference held in Dresden 24-25 September 2009.

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. In a direct injection engine, they noted, the cooling of the charge and consequent knock relief provided by the evaporation of the fuel is proportional to the fuel flow per unit mass of air.
