ABSTRACT:
A spark ignited internal combustion engine includes a counter which counts a predetermined number of the initial ignition signals during engine start and suppresses those ignition signals to prevent reverse torque due to excessive cylinder pressure before top dead center at the extra-low engine speed of initial start and thus assist engine start, especially in a warm engine. The counter is reset by detection of the closure of the ignition switch through the electric power supply line so that no separate wire from the start switch or motor is required.
