Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

The research by the University of Edinburgh measured the impact of diesel exhaust fumes on healthy volunteers at levels that would be found in heavily polluted cities. When assessed in the clinic, we showed that the vascular dysfunction associated with diesel exhaust inhalation is prevented by particle filtration.

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. Oxidation of engine-generated NO to NO 2 is critical in diesel engine emission control for reducing NO x and carbon soot from the tail-pipe exhaust.

New 3.7L V6 for 2011 Mustang Features Ti-VCT System Also Slated for 2.0L EcoBoost

Green Car Congress

Ford is introducing its 2011 Mustang with a new 3.7-liter, With a six-speed manual, the 2011 Mustang delivers 18 mpg city/29 highway, up from 18 mpg city/26 highway on the 2010 model with manual. This overlap control via Ti-VCT helps us eliminate compromises in the induction and exhaust systems. As a DOHC design, the 3.7-liter

SwRI simulations show turbocharged Scuderi Engine could reduce a standard 2011 Nissan Sentras fuel consumption by up to 35% on FTP cycle

Green Car Congress

Modelled results of fuel consumption in 2011 Nissan Sentra. The Sentra model was simulated through a standardized Federal Test Procedure-75 (FTP-75) drive cycle for each SSC engine design. Source: Scuderi. Click to enlarge. Preliminary results showed up to a 25% decrease in fuel consumption (i.e.,

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

In addition, the inhomogeneity of the fuel mixture under stratified operation in GDI engines during the compression stroke tends to contribute to higher particulate emissions compared to the exhaust emissions from traditional PFI engines. The midsize sedans were a 2011 2.4L —Chan et al. Volvo S40 PFI vehicle (PFI#1).

FEV to show 2nd generation diesel High Efficiency Combustion System at 2011 SAE World Congress

Green Car Congress

will exhibit its High Efficiency Combustion System (HECS) diesel engine at the 2011 SAE World Congress, 12-14 April at Cobo Center in Detroit. HECS is designed and tailored for high EGR tolerance and combines low nitrogen oxide emissions with superior fuel efficiency, even under high part load conditions.
