Abstract
A closed loop fuel control system for an internal combustion engine having in its exhaust system an exhaust composition sensor generating a signal indicative of air-fuel ratio in gases in the exhaust system and an integral controller providing integration on the generated signal for adjusting the ratio of air and fuel supplied to the engine, and a storage device which stores the output from the controller in response to a sensed particular engine operating parameter. The stored signal is later extracted in response to the sensing of the same engine operating parameter to rapidly vary the controller output.
