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). These individual class curves are then sales weighted to estimate fleet average compliance costs for a range of potential CO 2 standards.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. Finally, we analyze the potential climate effects of switching a PFI to a GDI fleet. —Saliba et al.

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. Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. Click to enlarge.
