Abstract

PURPOSE: To perform accurate operation through simple circuits, by providing an electronic controller with a first and a second groups of registers for retaining the results of comparison by a comparator.
CONSTITUTION: An input/output unit is provided to receive the signals of a plurality of engine running condition sensors and control actuators for an injection valve, and EGR unit, a fuel pump and an ignition coil depending on data calculated by a microprocessor on the ground of said sigbals. A pulse output circuit 126, which is a part of the input/output unit, has a stage counter 570 for controlling the processing stage, an incrementer 478 for correcting the data of a group of instantaneous registers 472 for regaining the instantaneous conditions of the engine, and the first and the second groups of registers 502, 504 for retaining the results of comparison by the comparator 480
