摘要： PROBLEM TO BE SOLVED: To achieve favorable main combustion during an air-fuel ratio switching period, so that torque shock is prevented.SOLUTION: A control device of an internal combustion engine switches the air-fuel ratio of in-cylinder gas from a lean first air-fuel ratio for normal operation to a rich second air-fuel ratio, and carries out intake air restriction during a switching period from the start t1 to the end t2 of the switching. A main injection M is performed at or around a compression top dead center, prior to the start of switching, and the main injection M and a first after injection A1 that results in incomplete combustion of injected fuel are performed after the end of switching. During the switching period, the main injection M is performed, and a second after injection A2 that results in incomplete combustion of injected fuel is performed at a time earlier than the first after injection A1.

摘要： After changing the required values of controlled variables of an inlet system and an EGR system (an air-fuel ratio, an EGR rate, and an intake air amount) into values of a combustion mode after switching with updating a required combustion mode mdcb, the present invention updates a combustion mode mdcbd for injection after waiting for the expiration of a delay period. Besides the update, the present invention updates the required values of a target injection pressure pc and a main injection timing ainjm, and the required values of a torque correction amount qdm, the waviness correction amount qdi, and the cylinder internal pressure correction amount qdp for a main injection amount command value qfinm into the values in a combustion mode after switching. The present invention gradually changes the target injection pressure pc, the main injection timing ainjm, the torque correction amount qdm, the waviness correction amount qdi, and the cylinder internal pressure correction amount qdp towards respective required values in the combustion mode after switching with keeping the gradual change extent of those uniform until a gradual-change period elapses.

摘要： 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. 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. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a premixed compression-ignition engine capable of suppressing a difference in a level of torque developed when switched from spark ignition combustion to premixed compression ignition combustion without using a complicated and expensive mechanism such as an in-cylinder injection system. SOLUTION: This premixed compression-ignition engine 1 performs operation by switching the spark ignition combustion and the premixed compression ignition combustion, and has a negative overlap period during a premixed compression-ignition combustion operation. The premixed compression-ignition engine 1 includes: an intake valve 11v and an exhaust valve 12v controlled by a variable valve mechanism; and a control means performing control in order to switch the exhaust valve 12v to take in internal EGR so that the valve closing timing of the exhaust valve 12v is delayed relative to required timing during the premixed compression-ignition combustion, after the intake valve 11v is switched before the exhaust valve 12v is switched so that the valve opening timing of the intake valve 11v is delayed relative to a top dead center, when switched from the spark ignition combustion to the premixed compression ignition combustion.
