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.

Co-Optima releases capstone report on first 4 years of work

Green Car Congress

Co-Optima estimations indicate that significant fuel economy improvements are possible with improvements to RON, S, and HOV. The report highlights researchers’ answers to three vital questions: What fuels do engines want? compression ratio, extent of downsizing, etc.). Source: Co-Optima capstone report.

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.

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

A 110cc pre-production prototype of a Pinnace Engine 4-stroke opposed piston scooter engine ( earlier post ) showed approximately a 27% improvement in fuel consumption across different scooter cycles compared to a conventional benchmark engine in dynamometer and simulation testing by FEV. That’s what needed all over Asia.
