摘要： An engine is provided with a variable valve mechanism capable of changing a degree of an operating angle and a phase of a valve-open period of an intake valve. A controller selectively executes at least one of a plurality of knock controls including a phase adjustment of the valve-open period of the intake valve when a knocking is detected by a knock sensor. When the operating angle of the intake valve is smaller than 180 degrees, a knock control is selected and executed such that a valve-open timing IVO of the intake valve does not exceed a predetermined timing (TDC+α) retarded from a top dead center TDC by a predetermined angle α. Specifically, for example, when the operating angle is smaller than 180 degrees and the valve-open timing IVO of the intake valve is after the top dead center TDC, the valve-open timing IVO is advanced.

摘要： There is provided an ignition timing control device for an internal combustion engine capable of appropriately performing knock learning by performing knock learning adapted to an engine combustion phenomenon. The inventor has found the principle of a knock reduction effect due to ignition retard is that “if a combustion period moves toward the retard side, a cylinder volume during the combustion period increases, resulting in curbing of rise in the temperature and pressure of unburned gas”. An ignition timing control device according to the present invention is capable of new knock learning based on the principle, which learns a “cylinder volume rate”. The cylinder volume rate is a parameter determined from the amount of change in cylinder volume. Even when an operational status changes, learned ignition timing obtained from knock control means can be set to an appropriate value by reflecting the learned cylinder volume rate.

摘要： A control pattern corresponding to a ultra high expansion cycle is executed, wherein an actual timing IVCa of an intake valve closing timing is controlled to agree with a steady adapted value IVCt, an actual value εma of a mechanical compression ratio is controlled to agree with a steady adapted value εmt, and an ignition timing SA is controlled to agree with a steady adapted timing SAt. There are four cases that might be generated, including a case in which the IVCa is shifted toward a retard angle side or toward an advance angle side from the IVCt due to a response delay of a variable intake valve timing apparatus, and a case in which εma is shifted to a greater side or to a smaller side from the εmt due to the response delay of a variable compression ratio mechanism.
