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). LEVIII will begin a four year phase-in of a tighter 1 mg/mile starting in 2025. Yang et al.

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 —Zimmerman. Naomi Zimmerman, Jonathan M. Wang, Cheol-Heon Jeong, James S. 6b01800.

The US Environmental Protection Agency (EPA) and the US Department of Transportation (DOT) formally unveiled their joint proposal to set stronger fuel economy and greenhouse gas pollution standards for Model Year 2017-2025 passenger cars and light trucks. The 163 g/mile limit would be equivalent to 54.5 mpg US (5.87 improvements.

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.

In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) With this charge it can travel an average daily distance of about 30 miles (50 km), which is often enough to serve most consumers’ needs. Both owners drove an average of 12,000 total miles in the year.
