Systematically reviewed are the fundamentals of Electronic Fuel Management (EFM). Included is a discussion of five EFM areas: 1) air sensing concepts 2) fuel metering concepts 3) fuel delivery to the cylinders 4) fuel preparation with the air 5) calculation hardware (ECM) Presented as a part of the air sensing section is a summary of the physical principles that may be applied to compressible fluid mass air flow rate measurement. Finally, an example of digital computer control of a timed speed density system is reviewed.
