To suppress increase of NOx in a case of performing combustion switching from homogeneous combustion to stratified combustion.SOLUTION: An ENG 1 includes a spark plug 16 and a fuel injection valve 17. A method for controlling the ENG 1 comprises: upon switching from homogeneous combustion to stratified combustion, retarding ignition timing IGT from ignition timing IGT1' when the magnitude of torque change ΔTq of the ENG 1 at the time of the combustion switching is equal to or less than a predetermined value ΔTq1; and advancing the ignition timing IGT so that a NOx change amount ΔN corresponding to the increase in an intake air amount Q of the ENG 1 after the combustion switching is equal to or less than a predetermined amount ΔN1.SELECTED DRAWING: Figure 5A

    【課題】均質燃焼から成層燃焼への燃焼切替を行う場合に、NOxの増加を抑制する。【解決手段】ENG1は、点火プラグ16と燃料噴射弁17とを備える。ENG1の制御方法は、均質燃焼から成層燃焼への燃焼切替の際に、当該燃焼切替の際のENG1のトルク変化の大きさΔTqが所定値ΔTq1以下になる点火時期IGT1´よりも点火時期IGTを遅角させ、且つ当該燃焼切替後のENG1の吸入空気量Qの増加に応じたNOx変化量ΔNが所定量ΔN1以下になるように点火時期IGTを進角させること、を含む。【選択図】図5A
