Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 本発明は直接燃料噴射内燃機関に関し、成層 燃焼方式で運転しているときのみならず予混合方式で運 転しているときにも理想的な点火作動を実現することを 目的とする。 【解決手段】 高回転・高負荷域では予混合方式で運転 し、低回転・低負荷運転域では成層燃焼方式で運転し、 予混合方式で運転すべきときは(ステップS2でYes)1回 点火式が採用され(ステップS3) 、成層燃焼方式で運転 すべきときは(ステップS2でNo) 多重点火式が採用され る(ステップS4)。 (57) Abstract: The present invention relates to a direct fuel injection internal combustion engine, and realizes an ideal ignition operation not only when operating in a stratified combustion mode but also when operating in a premixing mode. The purpose is to: SOLUTION: The engine is operated by a premixing method in a high rotation speed / high load range, and is operated by a stratified combustion method in a low rotation speed / low load operation range. When the operation is to be performed by the premixing method (Yes in step S2), the single ignition method is employed (step S3). When the operation is to be performed by the stratified combustion method (No in step S2), the multiple ignition method is employed. (Step S4).
