Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

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. A high octane fuel was injected late on the compression stroke of a boosted diesel engine operating with high EGR. Very low fuel consumption, NO x , and PM emissions were measured.

ICCT: 2025 target average of 70 g/km CO2 for new cars in EU feasible and economical; more so with electric drive

Green Car Congress

The FEV data are combined with supplemental data to generate CO 2 cost curves for ten EU vehicle classes (diesel B, C, D, E, SUV, and LCV classes and gasoline B, C, D, and E classes). Switching sooner from conventional gasoline and diesel vehicles to plug-in or battery electric vehicles would reduce compliance costs. Source: The ICCT.
