    摘要： A spark ignition type internal combustion engine comprises a variable compression ratio mechanism able to change a mechanical compression ratio, an actual compression action start timing changing mechanism able to change a start timing of an actual compression action, and an exhaust valve. At the time of engine low load operation, the mechanical compression ratio is maximized to obtain a maximum expansion ratio, and the actual compression ratio is set so that no knocking occurs. The maximum expansion ratio is 20 or more. The closing timing of the exhaust valve at the time of engine low load operation is made substantially intake top dead center. Due to this, even if operating the internal combustion engine in a state of a large expansion ratio, the temperature of the exhaust purification catalyst can be maintained at a relatively high temperature.

    摘要： An internal combustion engine provided with a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control a closing timing of an intake valve. An actual compression ratio and ignition timing in a predetermined standard state after completion of engine warm-up are stored in advance as a reference actual compression ratio and a reference ignition timing. When the engine temperature is low or the intake air temperature is low, at the time of engine high speed operation, the actual compression ratio is made to increase over the reference actual compression ratio, while at the time of engine low speed operation, the ignition timing is made to advance over the reference ignition timing.

    摘要： A spark ignition-type internal combustion wherein a first mechanical compression ratio control and a second mechanical compression ratio control are alternatively carried out, the first mechanical compression ratio control makes the mechanical compression ratio in the low engine load side operation area higher than that in the high engine load side operation area to increase the expansion ratio in the low engine load side operation area, the second mechanical ratio control makes the expansion ratio in the low engine load side operation area lower than that in the low engine load side operation area made by the first mechanical compression ratio control and a boost pressure control increases the boost pressure like a step change when the engine load becomes a set engine load in the low engine load side operation area or higher, is provided. The set engine load of the boost pressure control when the second mechanical compression ratio control is carried out is set higher than that when the first mechanical compression ratio control is carried out.

    摘要： In an internal combustion engine, a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control the closing timing of an intake valve are provided. The mechanical compression ratio is held at a maximum mechanical compression ratio at the engine low load operation side and gradually made to decrease as the engine load increases at the engine high load operation side. The actual compression ratio is held nearly constant at the engine high load operation side and is made to decrease as the engine load decreases at the engine low load operation side.
