<p>A closed loop engine control system for internal combustion engines is described. The control system is responsive to signals indicative of the presence or absence of oxygen in the exhaust gas of the engine and is operative to generate an output signal for receipt by a fuel delivery controller which will cause that fuel delivery controller to increase fuel delivery in the presence of oxygen molecules in the exhaust gas and to decrease fuel delivery in the absence of oxygen molecules in the exhaust gas in order to maintain the fuel delivery at the predetermined, and preferably the stoichiometric, air/fuel ratio mixture point.</p> |
