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

Green Car Congress

Using a diesel oxidation catalytic converter (DOC), the scientists of Karlsruhe Institute of Technology (KIT) and their partners found that the particle size and oxidation state of the platinum component during operation can be modified specifically and dynamically during operation. The project is funded with €960,000 (US$1.1 201707842.

VW introduces new, more efficient TSI engine generation; Miller cycle with higher compression and electric VTG turbo

Green Car Congress

The proven concept of the exhaust manifold integrated into the cylinder head has been retained. Increase in charge density through efficient exhaust gas turbocharging. A world-first for the TSI evo is the use of an exhaust gas turbocharger with electrically actuated variable turbine geometry (VTG).

Study finds noble metal clusters can enhance performance of catalysts and save resources

Green Car Congress

Researchers at the Karlsruhe Institute of Technology (KIT) have demonstrated that noble metal atoms may assemble to form clusters under certain conditions. These clusters are more reactive than the single atoms and, hence, exhaust gases can be much better removed. Graphics: Florian Maurer, KIT). —Jan-Dierk Grunwaldt.

VW introducing 1.8L EA888 Gen 3 engine in 2014 Jetta, Passat and Beetle; driving impressions

Green Car Congress

Key advances for Gen 3 are in weight reduction, friction reduction, and the internal exhaust cooling system. Like its predecessor, the engine has a cast-iron cylinder block and an aluminum-alloy cylinder head which now has the exhaust headers cast integrally. Integrated exhaust manifold with cooling.
