Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

However, during development, the project team was able to exceed the program expectation for engine-out NO x and exhaust temperature control in the catalyst warm-up mode and concluded that the tailpipe NO x targets can be met without the close coupled light-off SCR. Source: Achates Power.

New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

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.
