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.

U. Houston-led project looking for new exhaust treatment catalysts for low-temperature lean-burn combustion engines

Green Car Congress

million project to find new catalytic materials that work at lower exhaust temperatures, allowing automakers to build vehicles that operate more efficiently while retaining the ability to clean emissions before they leave the tailpipe. Catalytic converters clean vehicle exhaust into nitrogen, water and carbon dioxide.

Cummins & Tula demonstrate Diesel Dynamic Skip Fire (dDSF) cylinder deactivation; up to 66% reduction in NOx on CARB LLC #7

Green Car Congress

The collaboration work was carried out on a Cummins X15 Efficiency Series 6-cylinder diesel engine, which already offers class-leading fuel economy. The reduction of tailpipe NO x is achieved primarily by optimized exhaust temperature control, resulting in significantly improved conversion efficiency of the aftertreatment system.

BASF and Lutianhua plan to pilot a new lower CO2 DME production process

Green Car Congress

BASF will supply new, high-performance catalyst systems that enable one-step conversion of syngas to DME while Linde will provide its newly developed process design and engineering for direct DME synthesis. It owns a state level technical center, a Post-Doctoral Research Center and a Class B chemical engineering design institute.
