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.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. Given the high reactivity of diesel fuels compared to gasoline, the ignition and combustion of pre-mixed fuel-air charges poses a challenging control problem. Earlier post.). Earlier post.). At SC conditions, however (T?
