Advanced Automotive Fault Diagnosis, Second Edition

Engine management is a general term that describes the control of engine operation. This can range from a simple carburettor to control or manage the fuel, with an ignition distributor with contact breakers to control the ignition to a very sophisticated electronic control system. The fundamental tasks of an engine management system are to manage the ignition and fuelling, as well as other aspects, and to refine the basic control of an engine.
Many of the procedures and explanations in this chapter are generic. In other words the ignition system explained in the next sections may be the same as the system used by a combined ignition and fuel control system.
