Abstract
Apparatus for simulating the operating characteristics of an automobile engine. The ignition system of the engine is electrically simulated and an electrical signal representative of engine revolutions per minute under various engine operation conditions is generated. A transfer function derived for the engine is implemented to control generation of the electrical signal. Engine acceleration and deceleration is simulated. An oxygen sensor normally positioned in an exhaust system of the engine is simulated with an electrical signal representative of an output signal supplied by the oxygen sensor being generated. Operation of a first electromechanical device controlled by an engine control sysem is simulated as is the operation of a second electromechanical device. The apparatus is useful for testing and calibrating a feedback and automatic idle speed control system for the automobile.
