Audi S6 Avant 2002-2004, Audi RS6 2003-2004 – 4.2 Liter V8 5V Engine Mechanical,
Secondary air system The secondary air system is designed to enable catalytic converter to heat up and reach its operating temperature more quickly after a cold start. Principle of operation
Due to extra mixture enrichment during cold-start phase, an increased amount of unburnt hydrocarbons is carried in exhaust gas. The secondary air system improves the afterburning(oxidation) process in the catalytic converter, and in this way reduces toxic emissions. Heat generated by oxidation accelerates “light off” of catalytic converter and significantly improves
exhaust gas quality during warm-up
