摘要： A closed loop control system is disclosed for controlling the air-fuel ratio of an internal combustion engine. An oxygen sensor is connected into the control loop after engine warm up when the temperature has reached its operating temperature to maintain the air-fuel ratio close to the stoichiometric value. An engine roughness detector is connected into the control loop before the oxygen sensor has reached its operating temperature to maintain the air-fuel ratio close to a predetermined lean limit. A temperature sensor and switching means controlled thereby are provided to alternately connect the roughness detector and the oxygen sensor in the control loop.

摘要： An acceleration enrichment feature for a closed loop fuel management system controlling the air/fuel mixture delivered to an internal combustion engine to regulate the roughness of the engine at a predetermined level. The enrichment feature provides increased fuel to the engine for operator induced transient conditions proportionately by sensing the rate of change of throttle angle. A throttle angle position signal is modified by circuitry providing a transfer function that introduces a lag term into the throttle angle position signal which differentiating the signal to determine the rate of change of throttle angle. The modified throttle angle position signal is additionally corrected by the amount of roughness sensed by the closed loop control and enriched for rough operations of the engine beyond a threshold and leaned for smooth operations of the engine. Acceleration enrichment pulses of a frequency dependent on the magnitude of the corrected throttle position signal are then combined with the basic fuel injection pulses of the closed loop fuel management system to provide a desired A/F ratio during operator induced transients.
