New Mercedes-AMG SL 43 features engine with electric exhaust gas turbocharger derived directly from Formula 1

Green Car Congress

liter turbocharged M139 engine featuring an electric exhaust gas turbocharger. The turbocharger is operated via the 48-volt electrical system, which also feeds the belt-driven starter-generator (RSG). An electric motor around 1.6 Under the hood of the open-top 2+2-seater is an AMG-enhanced 2.0-liter

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. A key contribution to this performance must come from the exhaust gas aftertreatment system—across the entire speed and load range. This way, exhaust gas flows through DOC and SCRF before it enters the turbine.

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. With its abbreviated compression phase and long expansion phase, it was designed specifically for operation at partial load. Operation with the knock-resistant fuel CNG enables a higher 12.5:1
