Abstract
Overheating of a catalytic converter receiving exhaust gases from an internal combustion engine is minimized by providing an air-fuel mixture leaner than the stoichiometric ratio for combustion in the engine, maintaining the exhaust gases in an exhaust reaction chamber at relatively high temperature for a relatively long time period before conveying them to the catalytic converter, sensing deceleration conditions in the engine as a function of increase in intake vacuum intensity, and retarding the spark ignition timing and introducing supplemental air for combustion upon increase in vacuum intensity.
