摘要：Internal combustion engine includes spark plug, at least automaticallycontrolled tumble control valve (TCV, 24) and electronic control unit. Electronic controlunit detects the variation of the revolving speed and the from first to the 2nd TCVopening degrees of TCV opening degrees within the scope of control at least TCV ofengine and the revolving speed of engine. Electronic control unit is further configured to:(I) executes lean operation in the first operating area, (II) executes the chemically correctfuel of second operating area of operation, (III) controls air-flow in cylinder, so as to bymeans of at least rate of change of TCV change engine of the speed during igniting ofspark plug surrounding flow revolving speed the first engine speed region be less thanthe first operating area ratio immediately engine speed region in the second operatingarea.
