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.

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

In a recent simulation study reported in Porsche Engineering Magazine , Porsche Engineering examined the potential of hydrogen combustion engines. We have therefore developed a hydrogen combustion engine that aims to match the power and torque of current high-performance gasoline engines as a concept study. Source: Porsche.

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%. The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. The patented concept is the subject of an open-access paper published in Frontiers in Energy Research.

Siemens researching thermoelectric waste heat recovery for lower grade exhaust; industrial and mobile application

Green Car Congress

To date, exhaust gas has generally only been used if it was hundreds of degrees Celsius hot. For example, the gas turbines in natural gas power plants produce exhaust gas that is used to generate steam for the operation of a steam turbine. A lab demonstration model is currently under construction at CT.

New split-cycle concept to control diesel HCCI combustion

Green Car Congress

A team from Universita degli Studi di Pisa (Italy) and Rolf Reitz at the University of Wisconsin-Madison are proposing a novel combustion concept—Homogenous Charge Progressive Combustion (HCPC)—based on a split-cycle principle to control HCCI combustion in diesel-fueled engines. —Musu et al., SAE 2010-01-2107.
