New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. As cars have become more fuel-efficient, however, they use less energy and the temperature of the exhaust gases is lower, which makes it harder to clean up the pollutants. In addition to high reactivity at low operating temperatures, thermal durability is essential for the catalysts to survive the harsh conditions encountered in automotive exhaust.

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. In modern charged engines, however, exhaust gas aftertreatment (EAT) competes with the turbocharger for heat in the exhaust gas flow. This way, exhaust gas flows through DOC and SCRF before it enters the turbine.
