| description | PROBLEM TO BE SOLVED: To suppress the blowout of discharge spark generated between electrodes of an ignition plug in a spark ignition internal combustion engine including the ignition plug provided generally in a central portion of the upper wall surface of a combustion chamber and generating a tumble flow in the combustion chamber.SOLUTION: If an operating state of an internal combustion engine 10 is in a predetermined blowout range, partial lift is performed for reducing a lift amount of a needle 30 from a lift amount of full lift (left in FIG. 3(ii)). Since the partial lift can intensify a central portion of an intake air flow (left in FIG. 3(iii)), a tumble flow (ω tumble flow) different in shape from a normal tumble flow can be generated (left in FIG. 3(iv)). As a result, in an ignition period by an ignition plug 18, a gas flow velocity near the ignition plug 18 can fall within an ignitable flow velocity range (left in FIG. 3(v)).
【課題】燃焼室の上壁面の略中央部に設けられた点火プラグを備え、該燃焼室内にタンブル流が生成される火花点火式の内燃機関において、点火プラグの電極間に生じさせた放電火花の吹き消えを抑制する。【解決手段】内燃機関１０の運転状態が所定の吹き消え領域内にある場合、ニードル３０のリフト量をフルリフト時よりも小さくするパーシャルリフトを行う（図３(ii)左側）。パーシャルリフトを行うことで吸気流の中央部が強化されるため（図３(iii)左側）、通常のタンブル流とは異なる形状のタンブル流（ωタンブル流）を生成できる（図３(iv)左側）。よって、点火プラグ１８による点火時期において、点火プラグ１８近傍のガス流速を点火可能な流速範囲内に収めることができる（図３(v)左側）。【選択図】図３ |
