PROBLEM TO BE SOLVED: To provide a technology effective to realize proper engine ignition without increasing the number of timers of setting a current supply time to ignition coils assigned to an engine.SOLUTION: An engine ignition control device 1 includes: one current supply start timer TA and one current supply termination timer TB disposed to determine current supply times of ignition coils 41-43 respectively assigned to each of cylinders of an engine 30; and a microcomputer 10 as a control portion for continuously bringing the current supply start time Ta into an underflow state several times when current supply conditions of the ignition coils 41-43 are satisfied, starting timer count by the current supply termination timer TB in the underflow of the prescribed time excluding the last one, among several times, terminating the timer count by the current supply start timer TA in the underflow of several times of the current supply start timer Ta to start current supply to the ignition coils 41-43, and further terminating the timer count by the current supply termination timer TB to stop the current supply to the ignition coils 41-43 in the underflow of the current supply termination timer TB. |
