Advanced ADEPT 48V affordable mild hybrid on path to meet future ultra-low vehicle emissions

Green Car Congress

Ricardo believes the above package is very competitive with other fuel economy solutions such as full hybridization. The concept of “intelligent electrification” enables highly aggressive engine downsizing and down-speeding beyond what might normally be possible other than through more expensive hybridization approaches.

Downspeeding and supercharging with transmission optimization can deliver fuel economy improvement over downspeeding and turbocharging

Green Car Congress

Researchers from Southwest Research Institute (SwRI) and Eaton have demonstrated the application of downspeeding and supercharging a diesel vehicle, in conjunction with optimizing transmission gear ratios and the shift schedule, to deliver a greater improvement in fuel economy than a downsped and turbocharged configuration.

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.

Pinnacle Engine pre-production prototype opposed piston engine shows about 27% fuel consumption improvement across different scooter cycles compared to conventional engine

Green Car Congress

FEV performed engine mappings in a dynamometer test cell to evaluate the fuel economy of Pinnacle’s TP90 scooter engine compared to a benchmark engine (N15) from Pinnacle’s Asian OEM partner. This combination of variable compression ratio and our operating mode gets us huge fuel economy wins. That’s what needed all over Asia.
