Cadillac's New Electric V-Series Concept is Far From a Silent EV

The Truth About Cars

It was easy to make fun of Dodge and the “fake” exhaust it chose to employ on the new Charger EV, but it’s no longer the only one trying to capture the thrill of a performance gas engine with a silent electric powertrain underneath. The brand doesn’t currently offer a performance EV, but hot sedans are nothing new to the company.

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.

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.

LiquidPiston To Unveil Compact High Efficiency Engine at 2010 SAE World Congress

Green Car Congress

The thermodynamic efficiency of the HEHC cycle offers a 20% to 50% improvement over the best diesel engines, according to the company. For instance, intake/compression, combustion, expansion/exhaust are occurring simultaneously in separate chambers. This combination separates the working mixture into three separate volumes.

All companies acknowledged their involvement and agreed to settle the case. This is also a clear message to companies that cartels are not accepted. Between 1997 and 2004, meetings were held at senior manager level, sometimes at the margins of trade fairs or other events. —Commissioner for competition, Margrethe Vestager.

Michigan State University Receives $2.5M ARPA-E Award to Build Wave Disc Engine/Generator for Series Hybrid Applications

Green Car Congress

Wave rotor technology has been explored since 1906, although its first significant application was in 1940 by Brown Boveri Company (BBC, today ABB) which used it as a high pressure stage for a gas turbine locomotive engine. In axial-flow configurations, noted Müller and co-authors in a 2004 paper, pure scavenging is a challenging task.
