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. Nanostellar was founded in California in 2004 by scientists from Stanford University and NASA Ames Research Center.

The TEG technology, which converts waste heat from gas exhaust into electric energy and has the potential to improve passenger car fuel efficiency by as much as 5%. TEG & Exhaust System in Lincoln MKT. This follow-on light-duty vehicle project, funded in 2011, has a target of a 5% fuel economy improvement. Click to enlarge.

Achates Power wins $9M from ARPA-E to develop gasoline compression ignition medium-duty multi-cylinder opposed-piston engine

Green Car Congress

The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.

One of the trucks was equipped with exhaust gas recirculation (EGR); three were equipped with EGR and a selective catalytic reduction (SCR) device. EGRs were primarily introduced for on-road heavy-duty diesel engines over a decade ago to meet the tighter MY 2004 NO x standard (2 g/bhp-hr). high purity urea and 67.5%

The infringement covered the entire EEA and lasted 14 years, from 1997 until 2011, when the Commission carried out unannounced inspections of the firms. Between 1997 and 2004, meetings were held at senior manager level, sometimes at the margins of trade fairs or other events. This was complemented by phone conversations.
