<P>PROBLEM TO BE SOLVED: To provide an apparatus and method for controlling a compression self-ignited internal combustion engine, adapted to reduce combustion noise as well as fluctuations in torque during switching from spark-ignited combustion to compression self-ignited combustion. <P>SOLUTION: In accordance with information on an operational state of an internal combustion engine, a combustion mode switching discriminator 21 selects a compression self-ignited combustion mode if the engine is operating under the conditions that allow the compression self-ignited combustion. If the engine is operating under the conditions that do not allow the compression self-ignited combustion, the combustion mode switching discriminator 21 selects a spark-ignited combustion mode. Immediately after the combustion mode is switched from the spark-ignited combustion to the compression self-ignited combustion, a combustion mode switching corrector 28 outputs switching correction quantities with respect to operating quantities for the compression self-ignited combustion. The operating quantities for the compression self-ignited combustion are adjusted using the switching correction quantities that the combustion mode switching corrector 28 has output with respect to the operating quantities for the compression self-ignited combustion immediately after switching to the compression self-ignited combustion mode. The corrected operating quantities obtained from the adjustments are output as control quantities from a combustion mode selector 27. <P>COPYRIGHT: (C)2009,JPO&INPIT |
