ELECTRONIC FUEL INJECTION SYSTEMS UTILIZING CORONA DISCHARGE AIR MASS FLOW TRANSPORTATION

Accurate control of electronic fuel injection systems primarily requires a knowledge of the mass flow of air into the engine under all circumstances. The corona discharge air flow meter is one of the few transducers capable of measuring this quantity directly and this paper describes the application of such transducers to EFI control utilizing both digital and analogue electronic techniques. Problems of transducer accuracy and vehicle driveability encountered during extensive operating tests are also discussed. /GMRL/
