Abstract :
An approach to achieving uniform cylinder-to-cylinder air-fuel ratio control in the face of injector mismatch and unbalanced airflow due to engine geometry is presented. A key, feature of the proposed method is that it functions well with the switching-type exhaust gas oxygen sensor commonly used in today´s automobiles. The controller design from modelling to experimental implementation in a dynamometer test facility is documented.
