Transducers for Engine Management 730576

The particular difficulties encountered in designing fuel and ignition control in today's automobiles have led to consideration of electronic systems. These are totally dependent upon the transducers used to provide the information they require, and frequently the success of a given system depends upon the solution of some transducer problem. This paper discusses some of the alternative choices of input parameters to a control system intended to manage the fuel and ignition of an internal combustion engine. The requirements for, and designs for, transducers to measure throttle angle, crankshaft speed and position, air mass flow, engine component position, and exhaust quality are discussed.
