Fuel metering control system for internal combustion engine |
摘要 |
A fuel metering control system for an internal combustion engine including a feedback loop having an adaptive controller and an adaptation mechanism that estimates controller parameters ¸ . The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The adaptation mechanism is input with the controlled variable once per prescribed crank angle such as a TDC of a certain cylinder and estimates the controller parameters. Since, however, the input is limited to a specific cylinder¹s air/fuel ratio, the air/fuel ratio is averaged for all cylinders and used in the calculation. Similar averaging is made for the other parameters input to the mechanism or output from the controller.
