ABSTRACT:
An engine is equipped with an EGR system in which the amount of recirculated exhaust gases is controlled in response to an intake vacuum in an intake passage. The spark timing of the engine is controlled to advance in accordance with the increase of the amount of the recirculated exhaust gases so as to maintain stable engine running even under a considerably high EGR rate.
