Zusammenfassung:PROBLEM TO BE SOLVED: To provide an internal combustion engine control system that can efficiently prevent an engine part from corroding due to corrosive condensate water without changing a hardware configuration.SOLUTION: An internal combustion engine control system 100 includes: a condition determination part 301 for determining whether it is a condition where corrosive condensate water is likely to be generated in a combustion chamber, at engine stoppage; and a scavenging control part 302 for scavenging inside the combustion chamber by controlling a starter motor 110 to operate to crank an engine 200 at engine stoppage when the condition determination part 301 determines that it is a condition where corrosive condensate water is likely to be generated.SELECTED DRAWING: Figure 1 【課題】ハードウェア構成を変更することなくかつ効率的に、腐食性凝縮水によるエンジン部品の腐食を防止できる内燃機関の制御システムを提供すること。【解決手段】内燃機関の制御システム100は、エンジン停止時に、燃焼室内に腐食性凝縮水が生じ易い条件か否かを判定する条件判定部301と、条件判定部301によって腐食性凝縮水が生じ易い条件であると判定された場合、エンジン停止時にスターターモーター110を稼動させてエンジン200のクランキングを行わせることにより、燃焼室内を掃気する掃気制御部302と、を有する。【選択図】図1
