Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances. Click to enlarge.

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.

A study by Ricardo for the Renewable Fuels Association (RFA) concludes that the adoption of E15 as the blend limit for standard US pump grades of gasoline rather than the current E10 should not adversely affect vehicles manufactured between 1994 and 2000 in terms of their performance and durability based on normal specifications and usage profile.

Put another way, even when driving the conventional T6 model and accelerating briskly up a winding road, the driver has no idea that only a 2.0L (1,969 cm 3 ), 4-cylinder gasoline engine is doing the work. 2 Audi is also developing a gasoline-engine version of the Q7 e-tron specifically for the Asian markets China, Singapore and Japan.

A review of 43 studies of the effects of E15 (15% ethanol blends) on Model Year 2001 and newer cars by the National Renewable Energy Laboratory (NREL) found that the studies reviewed showed no meaningful differences between E15 and E10 in any performance category. The NREL report distinguishes between test fuels and test fluids.
