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

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). liter downsized turbocharged centrally-mounted direct injection engine.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

Green Car Congress

This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today. Regional highlights include: In North America, more engine downsizing is expected. The current average engine size is a 3.0-liter

Calls for an international 48V electrical standard for vehicles; looming WLTP implementation

Green Car Congress

the Worldwide harmonized Light vehicles Test Procedures (WLTP). The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone.

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. Organic gas emissions were the most sensitive to cold-start compared to the other pollutants tested.
