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

Green Car Congress

Bottom: Total particle-phase PAH emissions, expressed in ng/mile, for both test vehicles over the LA92 cycle. 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.

Porsche unveils 2017 version of 919 Hybrid Le Mans prototype

Green Car Congress

The engine combines downsizing turbo technology with efficient direct fuel injection; it delivers just under 500 hp (368 kW) and is the most efficient combustion engine from Porsche to date. The remaining 40% is generated by the exhaust energy recovery system. To recover exhaust energy, a small turbine is fitted in the exhaust tract.

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 significant fraction of the GDI PM 2.5 The extent of fuel-air mixing can be affected by injection system design. —Zimmerman.

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. engine calibration (spark timing, valve timing, etc.),
