What TEL does and what most anti detonates do, is resist prereaction during compression with in the normal ranges of compression ratios. Just as if you where to use ADI fluid, it "cools" the process, since most would agree that the H2O is not going to burn, especially at a much lower temperature than what disassociation would occure at.
It was very obvious that the cylinder head temperatures were lower with the highly leaded fuel vs the zero leaded fuel.
"lead deposites" Yes mostly lead bromide. If anything maybe its insulating.
And lead in a Catalytic converter, yes as its passing through so the Catalyst must have an affinity for lead.
