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.

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.

Former Commerce and Transportation Secretary Norman Mineta urges technology neutral policies in reaching proposed CAFE standards

Green Car Congress

The White Paper was published by the US Coalition for Advanced Diesel Cars, a national organization focused on promoting technology neutral policies and the energy efficiency and environmental benefits of advanced clean diesel technology. Current fuel economy policy clearly demonstrates this fact.

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.

Torotrak and Rotrex Establish Joint Venture to Speed Introduction of Variable Drive Compressor Technology for Boosting

Green Car Congress

The new venture, which will be called “Rotrak”, will add Torotrak’s variable speed traction drive to Rotrex’ supercharging technology to address the automotive industry’s need for affordable, effective engine downsizing technologies. The more established market for diesel pressure-charging is predicted to grow from 10.5

SAE High Efficiency IC Engine Symposium opens with consideration of alternative engine designs

Green Car Congress

An increase in pumping requirements for any reason carries a fuel economy penalty. Scuderi explained that “Millerizing” the Scuderi split cycle means downsizing the compression cylinder to get the over-expansion technique that is the core of the Miller approach—achieved in a convention engine by using early or late valve closing.
