Abstract

PURPOSE: To facilitate the decision of replacing time by accumulating the operational information of engine, then comparing said information with the replacing information of mounting parts to decide the replacing time and producing the replacing alarm on the basis of said decision.
CONSTITUTION: The control circuit 70 for driving/controlling the injector 12 and the ignition coil 58 of engine includes an input interface circuit 114 provided with the output signal from various detectors and CPU108, ROM110, RAM112 and EAROM (Alterable ROM) 122 are connected to said circuit. EAROM122 is a memory element for storing the running information of car such as running time, where the running information to be stored and updated in EAROM122 are such as the time information of timer operated at the engine drive, accumulated r.p.m., etc. When said accumulated by values reach to predetermined values, the lamps 224W 230 corresponding to the parts are lighted to alarm that the replacing time has come.
