摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine control device for effectively suppressing the progress of the deterioration of a catalyst accompanied by fuel cut while stably maintaining intake negative pressure.
SOLUTION: The control device comprises an exhaust valve train for varying valve timing for an exhaust valve, and an intake valve train for varying valve timing for an intake valve. During fuel cut in an internal combustion engine, an intake valve lift curve is changed from a normal lift curve 32 into a lift curve 36 where a maximum lift point is an intake TDC. By retarding the valve timing for the exhaust valve, the exhaust valve lift curve is changed so that closing timing for the intake valve is prior to closing timing for the exhaust valve (a lift curve 38).

摘要： PROBLEM TO BE SOLVED: To provide an intake control device for an internal combustion engine for controlling the opened/closed condition of an on/off valve in an intake passage cross section varying mechanism to mainly improve the response of a supercharger.
SOLUTION: In this device, the target condition of the on-off valve is set to be the opened condition in regions 1, 2 corresponding to a partial load operation region. Thus, pump loss is reduced in the partial load operation region to improve fuel consumption. On the other hand, the target condition of the on-off valve is set to be the closed condition in a region 3 as a high-load operation low-rotation region and to be opened condition in a region 4 as a high-load operation high-rotation region. Thus, torque in a low-rotation region and torque in a high-rotation region are both improved. When sudden acceleration is required in the case that the target condition is the opened condition (particularly in the regions 1, 2), the target condition is changed from the opened condition into the closed condition and then the target condition is fixed into the closed condition until predetermined conditions are established. Thus, the response of the supercharger is improved to increase the rising speed of supercharging pressure Pch during sudden acceleration.
