Air-Fuel Ratio Control Using a Simple Micro-Processor 770006

A control system is described which uses a simple micro-processor in conjunction with a control algorithm which utilizes engine speed and mass air flow to result in air/fuel ratio control of ±.5 A/F for the federal driving schedule.
A comparison is made to the conventional speed/density approach and the described micro-processor complexity is reduced; the memory requirements are halved; and the execution time is faster resulting in the possibility of assigning additional control task.
