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.

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. liter engine running as a full D-EGR engine from idle to full load, delivering more than 42% brake thermal efficiency with ultra-low exhaust emissions.

TARDEC, commented David Johnson, Achates President & CEO, in general has used COTS (Commercial Off-The-Shelf) engines, but is now looking for better fuel efficiency and is funding its own development activity; the solicitation won by Achates and AVL is a big departure for them, Johnson said. “ Earlier post.). We won on our data.

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%

For instance, intake/compression, combustion, expansion/exhaust are occurring simultaneously in separate chambers. Combining the high peak pressures produced during constant volume combustion with Atkinson expansion, which continuously extracts energy as exhaust gases expand to atmospheric pressure, delivers unprecedented fuel efficiency.
