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. Click to enlarge.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

Regulatory regimes seeking to reduce emissions from transport have largely focused on tailpipe emissions—i.e., the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. earlier post ). Background.
