To provide a controller of an internal combustion engine capable of further suppressing discharge of unburned HC.SOLUTION: A phase adjustment mechanism comprises a bypass passage 18 configured to, in a predetermined period, set a relative rotational phase so that an exhaust valve closes after an upper dead center position, to overlap valve opening timing of a suction valve and valve opening timing of the exhaust valve, to thereby connect an exhaust passage 12 of any cylinder K1 in an exhaust stroke, and an exhaust passage 12 of another cylinder K2 in a suction stroke at the same timing as the exhaust stroke.SELECTED DRAWING: Figure 5 【課題】未燃ＨＣの排出を一層抑制することができる内燃機関の制御装置を提供する。【解決手段】位相調節機構は、所定の期間において、上死点位置よりも後に排気弁が閉弁するように相対回転位相を設定することにより、吸気弁の開放時期と排気弁の開放時期とをオーバーラップさせ、排気行程にある何れかの気筒Ｋ１の排気通路１２と、排気行程と同時期に吸気行程にある他の気筒Ｋ２の排気通路１２と、を接続するバイパス通路１８が設けられている。【選択図】図５
