PURPOSE: To convert time data computed by means of a digital computer into actual time signals by a simple constitution and without false operation, about an energy transformation process synchronized with an engine-mainly, fuel injection or ignition timing setting.
CONSTITUTION: The computing data of a digital computer 1 are temporarily memorized to a latch port 2 while the data of the latch port are loaded to a down- counter 3 in synchronous with the angles of the revolution of an output shaft of an engine, and number is subtracted by clock signals with fixed frequency. Even when there happen troubles in the computer during control, engine can continuously be controlled on the basis of computing data already memorized to the latch port temporarily and in synchronous with the revolution of the engine, and the computer 1 can be returned to normalcy during that time.
