ABSTRACT:
In an internal combustion engine intended to be run on a leaner-than-stoichiometric mixture, intake control means which when "enabled" permit introduction of supplementary air under deceleration conditions to prevent over-enriching which would otherwise occur when the fuel film on the induction system wall abruptly evaporates. At various temperatures, the feature is disabled completely or for short periods of time so as not to cause over-leaning of the mixture at excessively cold temperatures, or at start up at cold or merely warm conditions.
