Dynamically tuning the structure of platinum in catalytic converters to enhance performance under different conditions

Green Car Congress

Researchers from France and Germany are proposing a new concept for the dynamic tuning of the structure of platinum nanoparticles on catalytic converters to enhance their performance—especially after cold starts and in urban traffic—and to reduce the consumption of expensive noble metal.

Audi introduces new CNG A3 Sportback

Green Car Congress

Its turbocharger with variable turbine geometry makes optimal use of the exhaust gas energy for early and harmonious torque development. The cylinder head, injection system, turbocharger and catalytic converter were modified accordingly for the CNG engine. The A3 Sportback 30 g-tron 1.5 lb-ft) of torque between 1,400 and 4,000 rpm.

MAHLE developing portfolio of solutions for fuel cell drives in commercial vehicles

Green Car Congress

The water balance of a polymer electrolyte fuel cell significantly affects efficiency and service life. If the diaphragm dries out, this will lead to a gas breakthrough, while surplus water has the undesired effect of allowing the gases to freely enter the catalytic converter. Exhaust pathway. Humidifier.

ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

Theoretically, cars operating on higher ethanol blends than the design point could emit greater concentrations of pollutants in exhaust gas. In the cylinder where combustion takes place, the fuel evaporates before it is burned, and this evaporation helps cool off the air/fuel mixture and exhaust gas.

Mærsk, Wallenius Wilhelmsen, BMW Group and others partner to explore blend of lignin and ethanol for sustainable shipping fuel

Green Car Congress

Lignin is a structural bio-polymer which contributes to the rigidity of plants. While bioethanol is not a drop-in fuel, the residual lignin can be converted to a drop-in fuel via thermal treatments such as gasification or solvolysis. Initiatives such as the LEO Coalition are an important catalyst in this process.

US Air Force Office of Scientific Research Makes Two Awards for Thermoelectric Waste Heat Recovery Technology

Green Car Congress

Such devices can recover some of the energy embedded in waste heat, such as that produced by exhaust gas from an engine. All currently used thermoelectrics are semiconductors, so our development of polymer-based materials is novel. Earlier post.). Jaime Grunlan. Of particular interest is the use of these devices in military operations.
