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.

摘要： In a variable compression ratio internal combustion engine in which the compression ratio is changed by changing the combustion chamber volume, the present invention enables to inhibit irregularities in the air-fuel ratio involved by changing of the combustion chamber volume. In a transition period during which the compression ratio is changed, the actual volume of the combustion chamber realized by a compression ratio changing mechanism is detected. A factor that influences the air-fuel ratio (for example, fuel injection quantity, cylinder intake air quantity or amount of EGR) is controlled based on the actual volume of the combustion chamber thus detected to make the air-fuel ratio substantially equal to that before and after the change of the compression ratio.

摘要： When knocking occurs, a control apparatus for an internal combustion engine increases the rotational speed of a pump to increase the flow rate of a coolant supplied to an area near a combustion chamber wall surface, and controls an actual mechanical compression ratio to a low mechanical compression ratio lower than a mechanical compression ratio set based on the load of the engine. Thus, the pressure of end gas is decreased, and occurrence of knocking is suppressed. Then, the actual mechanical compression ratio is returned to the mechanical compression ratio at a time point at which the temperature of the combustion chamber wall surface has been sufficiently decreased due to the increase in the rotational speed. Thus, occurrence of knocking is suppressed while avoiding the situation where the actual mechanical compression ratio continues to be controlled to the low mechanical compression ratio that is lower than the mechanical compression ratio.

摘要翻译： 当发生爆震时，用于内燃机的控制装置增加泵的旋转速度，以增加供应到燃烧室壁表面附近的区域的冷却剂的流量，并将实际机械压缩比控制到低机械压缩 比低于基于发动机负载设定的机械压缩比。 因此，末端气体的压力降低，并且抑制了爆震的发生。 然后，由于转速的增加，在燃烧室壁面的温度已经充分降低的时间点，实际的机械压缩比返回到机械压缩比。 因此，抑制了发生爆震，同时避免了实际的机械压缩比继续控制在低于机械压缩比的低机械压缩比的情况。

摘要： A spark ignition type internal combustion engine comprises a variable compression ratio mechanism able to change a mechanical compression ratio, a variable valve timing mechanism able to control a closing timing of an intake valve, and an air flow control valve controlling an air flow in a cylinder and able to control the amount of intake air fed into a combustion chamber. The mechanical compression ratio is made maximum so as to obtain the maximum expansion ratio at the time of engine low load operation and the actual compression ratio at the time of engine low load operation is made an actual compression ratio substantially the same as that at the time of engine medium and high load operation. When the engine load is in an extremely low load region, the air flow control valve is used to control an amount of intake air fed into the combustion chamber. Due to this, a high heat efficiency can be realized even in a region where the amount of intake air is difficult to control by changing the closing timing of the intake valve.
