Their study is publishedin the ACS journal Environmental Science & Technology. The found that using a GPF did not show any fuel economy and CO 2 emission penalties, while the emissions of total hydrocarbons (THC), carbon monoxide (CO), and nitrogen oxides (NOx) were generally reduced.

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. Finally, partial hybridization using the 48V powertrain may be integrated to improve fuel economy. —Abdellahi et al.

Based on the results of the study, CAR believes the economic risk to the auto industry connected to mandating permanent fuel economy standards in the long run is “ very serious ” The group recommends periodic review to assess the rate of technology development and cost reduction of advanced technologies leading up to 2025.

The EU has already set a standard for 6 × 10 12 number/km limits between 2014 and 2017, tightening to 6 × 10 11 number/km.). Homogeneous GDI provides fuel efficiency benefits from charge air cooling, more facile turbocharging, and the downsizing that these permit. —Maricq et al. The PM is predominantly (?80?90%)

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.
