Talk:NOx adsorber

Merger proposal

I just found that the page NOx_Absorber appears to be the same to this page. Are these two different names for the same thing? Probably a merger and/or re-direction is needed? UnknownC (talk) 19:03, 23 June 2009 (UTC)

I've just noticed the time - it's off to bed, will try to get back to this later. UrbanTerrorist 05:41, 21 January 2006 (UTC)

That's a long sleep you've had!--King Hildebrand 12:24, 16 June 2007 (UTC)

They were merged, and a redirect performed, but the Merge was never removed. That has been done now. Consider the issue closed. UrbanTerrorist (talk) 05:12, 2 February 2012 (UTC)

Updated Information

The article suggests that NOx catalysts aren't used on any production vehicles due to their expense and high technology, but the Honda Insight used NOx adsorbers since their introduction (in addition to a conventional 3-way catalyst). To purge the catalyst, rather than spray fuel onto the mesh, the engine ran rich for a while. Through the use of two O2 sensors, the ECU would automatically alter the AFR between lean burn operation and purging. LostCause (talk) 21:28, 15 December 2007 (UTC)

Updated Information

The first Toyota patents came out already early 90s. The first vechicle in production was 1996. All on Lean-burn petol cars —Preceding unsigned comment added by 57.67.17.100 (talk) 06:44, 17 June 2009 (UTC)

commercialization

Plus, the Dodge Ram has had NOX adsorbers since 2007. The Mercedez do now as well (with SCR). Wepling (talk) 01:37, 11 January 2010 (UTC)

Volkswagen emissions scandal

The article mentions a 2008-era introduction of NOx adsorbed technology in VW "clean diesel" engines. These are, apparently, the ones involved in the Volkswagen common-rail TDI diesel engine emissions scandal (cf. Volkswagen#Defeat_device_scandal). — Preceding unsigned comment added by 134.4.251.28 (talk) 18:28, 22 September 2015 (UTC)
