Summary:PROBLEM TO BE SOLVED: To keep lubricant performance and prolong a lubricant life at the maximum.SOLUTION: In an internal combustion engine in which a fuel injection valve directly injecting fuel to a combustion chamber is arranged, when a lubricant dilution ratio is high, a fuel injection time per fuel injection is made shorter than that in a case where the dilution ratio is low. Provided is a control device of an in-cylinder fuel injection type internal combustion engine characterized that an injection number per combustion cycle is increased. 【課題】 本発明は、上記のような実情を鑑みてなされたものであり、潤滑油の性能を保ちつつ、且つ、潤滑油寿命を最大限に伸ばすことを目的としている。【解決手段】本発明では、燃焼室内へ直接燃料を噴射する燃料噴射弁が配置されている内燃機関において、潤滑油希釈割合が高い場合、希釈割合が低い場合と比較して燃料噴射１回あたりの燃料噴射時間を短くする、または１燃焼サイクルあたりの噴射回数を増加させることを特徴とする筒内燃料噴射式内燃機関の制御装置を提供する。【選択図】 図９
