Delphi and partners advancing with high-efficiency, low-emission gasoline compression-ignition combustion

Green Car Congress

A key strategy for achieving the project goals is the further development of a new low-temperature combustion system: gasoline direct-injection compression-ignition (GDCI). At a low-load condition of 1500 rpm-2 bar IMEP, Delphi used a secondary-exhaust-valve-lift event to rebreathe hot exhaust gas and promote autoignition.

2024 Dodge Charger Daytona: the ‘Brotherhood of Muscle’ goes electric – Charged EVs

Baua Electric

The 2024 Dodge Charger Daytona is a Detroit anomaly: it’s a passenger car in an age of trucks and SUVs, it’s battery-electric when U.S. The Charger will also have a version with a gasoline engine (the electric one is the “Daytona”)—but every version of the EV will outperform its gasoline counterpart. What about charging rates?
