During its recent Innovation Day presentations ( earlier post ), PSA Peugeot Citroën announced that it will commercialize high-efficiency gasoline engines featuring dedicated exhaust gas recirculation (D-EGR), derived from a collaborative program with SwRI in the US. PSA has filed for two patents on its work. PSA concept D-EGR engine.

A higher compression ratio can be used if an engine will operate primarily at light loads, such that degraded efficiency at high loads is more than offset by improved efficiency at light loads.

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. A new study by a team at the University of Toronto has made a preliminary assessment of the climate trade-off (i.e., mpg (10.99

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

The new funding opportunity ( DE-FOA-0001461 ) will advance the long-term objective of the Co-Optima initiative to accelerate widespread deployment of significantly improved fuels and vehicles (from passenger to light truck to heavy-duty commercial vehicles) by 2030. Careful studies aimed at clarifying these interactions are needed.

Compared to new diesel engines, the Delphi team found that BSFC for GDCI at light loads was comparable or better, and at high loads was about 5% higher. Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. Current study.
