PURPOSE: To simplify construction of a device further form the device in a small size so as to reduce its cost, by generating injection start signals from outputs of a distributor circuit, which generates distributive signals from an engine speed reference signal and a rotary angle signal, and from an injection timing pulse.
CONSTITUTION: When a distributor relating to the present invention is applied to a six-cylinder engine, this distributor has a distributor circuit 50, which generates distributive signals (cWh) by an engine speed reference signal (a) and a rotary angle signal (b), and AND circuits 511W516 which operate a logic function between these distributive signals (cWh) and an injection timing pulse (i) generated by a microcomputer in the preceding stage. Further this distributor has delay switching circuits 521W526, which input injection start signals being outputs of these AND circuits 511W516, and a serial receiver circuit 53 which inputs serial data assigning the injection timing generated by the microcomputer. Then an injector, in accordance with parallel data converted in this receiver circuit 53, is operated to be controlled by the delay switching circuits 521W526 through drivers 541W546.
