Abstract

　内燃機関の燃料供給制御装置は、インジェクタと、デリバリパイプと、電磁リリーフ弁と、電子制御装置とを備える。インジェクタは燃料を噴射する。デリバリパイプはインジェクタに燃料を供給する。電磁リリーフ弁はデリバリパイプ内の燃料をリリーフ可能である。電子制御装置は、リリーフ機構の動作状態を、デリバリパイプ内の燃料がリリーフされるのを阻止する閉鎖状態とデリバリパイプ内の燃料がリリーフされるのを許容する開放状態との間で切り替える。電子制御装置は、第１のリリーフ処理と第２のリリーフ処理とを行うように構成される。第１のリリーフ処理は、内燃機関の停止直後に電磁リリーフ弁の動作状態を開放状態に維持してその後に閉鎖状態に維持する。第２のリリーフ処理は、第１のリリーフ処理が終了した後に電磁リリーフ弁を再び開放状態に維持してその後に閉鎖状態に維持する。
