Abstract
A target homogeneous mode throttle opening TA that is suitable for homogeneous stoichiometric combustion without EGR is computed regardless of the current combustion mode. During homogeneous stoichiometric combustion without EGR, the opening of a throttle valve is controlled based on the target opening TA . During homogeneous stoichiometric combustion with EGR, an opening adjustment value TAo is added to the target opening TA and the resultant is set as a target EGR throttle opening TA . The opening of the throttle valve is controlled based on the target opening TA . During stratified lean combustion, the fuel injection amount is controlled based on a hypothetical throttle opening TA , which corresponds to the target opening TA . In either combustion mode, the engine torque is adjusted based on a common control value, which is the target opening TA . Therefore, the engine torque is not abruptly changed when the combustion mode is switched.
