ABSTRACT:
An arrangement to carry out an enrich delay control operation without fail, start an enrich control operation after an elapse of a predetermined time with certainty, and improve control reliability. For this purpose, control means is provided with functions to (1) store a previous throttle full opening time upon reception of a throttle opening signal from a throttle sensor for detecting a throttle opening of a throttle valve, (2) obtain a new throttle full opening time by integrating a current throttle full opening time under predetermined conditions for identifying continuous full-open acceleration, with a previous throttle full opening time, (3) store the new throttle full opening time as the previous throttle full opening time when the new throttle full opening time is less than the predetermined time, and (4) start the enrich delay control operation of the internal combustion engine when the new throttle opening time is greater than or equal to the predetermined time.
