Closed loop air/fuel ratio control system |
摘要 |
A closed loop fuel controller for a vehicle internal combustion engine is responsive to the oxidizing/reducing conditions in the exhaust gases from the engine to provide a control signal for adjusting an air and fuel supply means and which varies in a sense tending to produce a predetermined air/fuel ratio. When the engine operation changes from one condition to another condition representing an acceleration or deceleration transient, the value of the air/fuel supply adjustment is preset to a value from a memory location addressed by the engine condition determined to produce the predetermined air/fuel ratio when the engine is accelerating and to a value from another memory location addressed by the engine condition determined to produce the predetermined air/fuel ratio when the engine is decelerating so that the air/fuel ratio adjustment is substantially instantaneously preset to the value determined to produce the predetermined ratio during engine accelerating and decelerating transient conditions.
