摘要： In an engine controller capable of carrying out spark ignition type combustion and compressed self-ignition type combustion, in order to suppress operation performance deterioration and exhaust performance deterioration at the time of switching a combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion, intake pipe pressure downstream a throttle is quickly reduced by making the throttle opening degree smaller than a target throttle opening degree of the spark ignition type combustion immediately after switching for a certain period during the combustion mode is switched from the compressed self-ignition type combustion to the spark ignition type combustion. As a result, responsiveness of an intake amount at the time of switching the combustion mode from the compressed self-ignition type combustion to the spark ignition type combustion is enhanced, and combustion switching without exhaust deterioration and torque variation is realized.

摘要： In a homogeneous charge compression-ignited internal-combustion engine, based on information regarding the operational state of the engine, a combustion mode switching discriminator selects a homogeneous charge compression-ignited combustion mode if engine operating conditions allow homogeneous charge compression-ignited combustion. If not, the combustion mode switching discriminator selects a spark-ignited combustion mode. Immediately after switching from spark-ignited combustion to homogeneous charge compression-ignited combustion, a combustion mode switching corrector outputs switching correction values for operating quantities for homogeneous charge compression-ignited combustion. The correction values are used to adjust the operating quantities for homogeneous charge compression-ignited combustion, and new operating quantities obtained from the adjustments are output as control quantities from a combustion mode selector.
