Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.

PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. NO oxidation products such as nitrogen dioxide (NO 2 ) have a higher trapping efficiency on LNT materials. Graham, Burtron H. doi: 10.1126/science.1225091.

Volvo Car Corporation Confirms Introduction of PHEV Diesel in 2012; C30 BEV Production in 2011

Green Car Congress

Volvo Cars confirmed that it will introduce a series-produced plug-in hybrid diesel as early as 2012. Volvo had first suggested the 2012 date for a diesel PHEV in September 2009. Volvo’s BEV, the C30 DRIVe Electric ( earlier post ), will go into production in early 2011 and run in test fleets in Europe, China and the US.
