Air-fuel ratio control device for internal combustion engine |
| abstract |
Even when the control range of the air-fuel ratio of a combustion mixture is limited, it is possible to appropriately control the air-fuel ratio of the exhaust gas downstream of the exhaust purification device, thereby improving the exhaust gas characteristics. An air-fuel ratio control apparatus for an internal combustion engine capable of An air-fuel ratio control apparatus 1 for an internal combustion engine 3 uses a first feedback control algorithm [Expressions (17) to (27)] to converge an output value VO2 of an oxygen concentration sensor 22 to a target output value VO2_TRGT. As described above, the post fuel is controlled so that the output value VO2 of the oxygen concentration detecting means converges to the target output value VO2_TRGT by using the second feedback control algorithm [Equations (32) to (42)] while controlling the intake air amount. Controls the injection amount Gpost. The first feedback control algorithm is configured such that the convergence speed of the output value VO2 to the target output value VO2_TRGT is slower than the convergence speed of the output value VO2 to the target output value VO2_TRGT in the second feedback control algorithm.
