?, sensor just monitors the exhuast so that it goes it can be a C/L system.
Mantains AFR as things wear.

If the EPA had been not so pro oil, and wanted to save resources then we'd
be using WBs and saving resources.   They relied on a report writting by
jerks, IMO.  The 14.7 works for the perfect fuel molecule, which exists only
on blackboards,  I've never seen the formula work out with Sulfur in the
equation....

Closed loop is a modern marvel, just they picked the wrong numbers.
