    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： 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： 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.

    摘要： Provided is a spark ignition type internal combustion engine comprising a variable compression ratio mechanism (A) capable of changing a mechanical compression ratio, and a variable valve timing mechanism (B) capable of controlling the closing timing of an intake valve. At an engine low-load running time, the mechanical compression ratio is made so higher than that at an engine high-load running time that the expansion ratio may be 20 or higher. In case the vacuum in an engine intake passage is lower than the required vacuum, the opening of a throttle valve (17) is reduced, and the valve closing timing of the intake valve is controlled so that the intake air in a quantity according to the engine load may be fed to the inside of a combustion chamber in accordance with the opening of the throttle valve. As a result, a brake booster or the like can be properly activated in the internal combustion engine having its mechanical compression ratio enlarged at the engine low-load running time.

    摘要： In a variable compression ratio internal combustion engine that controls the compression of an internal combustion engine by changing the volume of the combustion chamber of the internal combustion engine in an axial direction of the cylinder, when a target compression ratio (εt) based on an operating condition of the internal combustion engine is at a reference compression ratio (ε0) or greater (S102), the compression ratio is changed to the target compression ratio (S103). When the target compression ratio (εt) is lower than the reference compression ratio (ε0) (S102), a control is executed to change the compression ratio and also to strength the tumble flow in the combustion chamber (S104).
