Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

Their study is publishedin the ACS journal Environmental Science & Technology. Polycyclic aromatic hydrocarbons (PAHs) and nitrated PAHs were quantified in both the vapor and particle phases of the PM, with the GPF-equipped vehicles practically eliminating most of these species in the exhaust. —Yang et al.

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR

Green Car Congress

Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK).

ETH Zürich Developing Pneumatic Hybrid Engine; Approaches Hybrid-Electric Performance at Lower Cost

Green Car Congress

The pneumatic hybrid engine, which follows the downsizing and supercharging paradigm, offers a fuel-saving potential that is almost equal to that of hybrid electric powertrains while inducing much lower additional mass and cost penalties, according to the ETH Zürich researchers. The compressed air supply also allows extreme downsizing.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

Researchers in an unrelated study of direct injection natural gasoline engines (dual-fuel combustion in CI-engines using RCCI as well as conventional duel-fuel combustion) at Chalmers University (Sweden) noted that methane’s very high octane number allows the use of high compression ratios in spark ignition engines.

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

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.,
