In four campaigns over the year-long study, the team from the University of Toronto measured emissions 15 meters from the roadway, then converted the measurements to fuel-based emission factors (EFs). Hence, GDI PM mass loadings and chemical composition may vary depending on the measurement environment or exhaust conditioning.

The study follows another recent ICCT report showing that the gap between official and real-world fuel-economy figures in Europe has risen to about 38%. The testing of the US-spec vehicles certified to the US Tier 2 Bin 5/California LEV II standard was commissioned to West Virginia University (WVU) by the ICCT.). Earlier post.).

The project researches key innovative technologies that will improve fuel economy and reduce exhaust gas and noise emissions by having a distributed propulsion system architecture. This will give a noise reduction and allows the filtering of particles in the long exhaust duct at the back of the engine.

In a policy analysis in the ACS journal Environmental Science & Technology , researchers from the Universities of Cambridge, Exeter and Oxford argue that, due to the increased emphasis on alternative fuels with drastically differing energy densities, vehicle efficiency should be evaluated based on energy rather than volume.
