Abstract
PURPOSE: To promote responding and operating efficiency by discriminating each cylinder on the basis of a signal issued once on every explosion in the same cylinder among a plurality of cylinders for injecting fuel successively into said plurality of cylinders in accordance with a previously determined order.
CONSTITUTION: A rotation suction-amount signal and other signals corresponding to various operation states of an engine such as engine temperature, atmospheric temperature and pressure, and so on are inputted into a microprocessor M0, and the amount of fuel to be injected corresponding to an operational state of the engine is worked out by a calculation based on a main program and memorized in RAM. When a specific ignition signal and a reference position pulse are given, an interruption is provided. On every interruption, the information of injected fuel amount on the basis of the newest result of calculation is written into output control circuits C1WC6 for actuating one among injection valves J1WJ6.
