The Microcomputer Based Engine Control System for the IIEC-2 Concept Car 790508
The microcomputer based ignition timing, EGR and fuel injection control system for the IIEC-2 concept vehicle is described. The techniques used to compensate the fuel delivery for EGR, to minimize response time and to compensate for engine and injector non-uniformity are emphasized. These measures, in conjunction with limit cycle air/fuel ratio control utilizing feedback from an exhaust gas oxygen sensor, are examined with respect to the effect on three-way catalyst performance.
