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

Green Car Congress

NO conversion versus ramp-up and ramp-down temperatures for MnCe-7:1 (?), 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. SmMn 2 O 5 (?), GdSrCeMn 7 O 14.83 (?), and Pt (?). Click to enlarge.

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

The US Environmental Protection Agency (EPA) is proposing to make it easier for manufacturers to gain approval to sell fuel conversion systems. The proposed rule would cover conversions of light-duty vehicles and heavy-duty highway vehicles and engines, and would apply to all clean alternative fuels. Exhaust, Evap, and OBD testing 2.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

Southwest Research Institute (SwRI) has built a demonstrator vehicle, based on a 2012 Buick Regal GS, incorporating the latest D-EGR (dedicated EGR) technology ( earlier post ), an outgrowth of SwRI’s HEDGE (High Efficiency Dilute Gasoline Engine) consortium projects ( earlier post ). In 2013, SwRI reported a 2.0-liter

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand.

Achates Power opposed-piston diesel for TARDEC will demonstrate multi-cylinder configuration

Green Car Congress

Achates Power says that its 2-stroke OP engine offers higher best point brake thermal efficiency than diesel or gasoline engines. Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. During blow down, the intake is closed so only exhaust gas leaves the cylinder via the exhaust ports.

SwRI simulations indicate Scuderi split-cycle engine consumes 25% less fuel than comparable conventional engine in Cavalier; 36% reduction with hybrid configuration

Green Car Congress

two split pairs) operating in a 2004 Chevrolet Cavalier would consume 25% less fuel under the FTP (Federal Test Procedure) than the comparable standard gasoline engine, while matching power and torque. A naturally aspirated Scuderi Air-Hybrid configuration consumes 30-36% less fuel under similar drive conditions, the simulations found.
