    摘要: Removal of fine particles by oxidation or/and sulfur poisoning recovery control may be required when an internal combustion engine has been in an extremely low load state for a predetermined period or more. In this case, the engine speed of the internal combustion engine (1) is adjusted to a range where the temperature of a filter (20) can be raised by heat-up control. The heat-up control is then executed by a filter temperature control means to raise the temperature of the filter (20) to a predetermined value. When the filter (20) reaches the predetermined temperature by means of low-temperature combustion, post-injection, VIGOM-injection, addition of 10 fuel to an exhaust system and the like, removal of fine particles by oxidation or/and sulfur poisoning recovery control for eliminating sulfur poisoning of a NOx absorbent are conducted. Removal of PMs captured by the filter and sulfur poisoning recovery control of the NOx absorbent can thus be conducted even if the internal combustion engine is left in an extremely low load operational state.

    摘要: In a device for controlling an engine, comprising combustion noise suppressor for suppressing combustion noise of a combustion chamber and controller for controlling the combustion noise suppressor, the device further includes control amount setter for setting a control amount of the combustion noise suppressor so that target combustion noise characteristics corresponding to a required amount of acceleration or deceleration exhibit a slower change in combustion noise than combustion noise characteristics corresponding to output characteristics of the engine over before and after acceleration or deceleration, wherein the controller controls the combustion noise suppressor according to the control amount set by the control amount setter. On the event of a rapid acceleration, a rapid change in the combustion noise in the initial stage of the acceleration is prevented to improve driving comfort.

    摘要: According to the present invention, each of the cylinders of an engine is provided with a first and a second swirl ports for generating a swirl of intake air in the cylinder. The second swirl port is located at the position downstream of the first swirl port with respect to the direction of swirl generated by the first intake port. The helical air passages of the first and the second intake port have a bottom which opens to the cylinder and an upper wall facing the bottom and an end wall defining the end of the helical air passage. The angle .theta..sub.1 between the upper wall and the end wall of the helical air passage of the first (upstream) intake port is formed smaller than the same (the angle .theta..sub.2) of the helical air passage of the second (downstream) intake port. By forming the angle .theta..sub.1 small, intake air flowing through the first intake port rotates a large amount before it flows into the cylinder and a strong swirl is formed by the intake air from the first intake port. On the other hand, since the angle .theta..sub.2 is relatively large, intake air flowing through the second intake port flows into the cylinder before it rotates sufficiently. Therefore, the intake air from the second intake port flows into the cylinder without interfering with the swirl in the cylinder. Thus, the flow resistance of the second intake port decreases.
