    • A spark plug (10) includes a plug body (51), a center electrode (52), a ground electrode (53) and injection control side poles (61, 62, 63). The ground electrode has an end portion (53a) opposing the end of the center electrode in a direction indicated by arrow A parallel to the axis of the plug body. A tip (53b) of the ground electrode and a tip (60a) of the injection control side poles (61, 62, 63) are positioned in substantially the same plane (71) perpendicular to the axis (C). The ground electrode (53) and the injection control side poles (61, 62, 63) are arranged at substantially regular intervals around the center electrode (52).

    • An electronic control unit (40) for controlling an internal combustion engine drive executes a first operation mode for injecting a fuel in a suction stroke while making an air/fuel ratio feedback control, when a demand for improving output characteristics is made in a medium/high load drive state of the engine. In response to a demand for raising the temperature of a catalyst, moreover, the first operation mode is switched to a second operation mode in which the fuel is injected in a compression stroke while making an air/fuel ratio feedback control performing a predetermined air/fuel ratio in the vicinity of a stoichiometric air/fuel ratio as a target value. At the time of switching to each of these operation modes, moreover, the air/fuel ratio correction coefficient of the air/fuel ratio feedback is increased/decreased to promote a shift of the output turning point of an O2 sensor (22) thereby to prevent such an instability of the air/fuel ratio control as is caused by the shift of the target air/fuel ratio accompanied with the switching to each operation mode. As a result, the temperature of an exhaust purifying catalyst (3) is raised in the second operation mode for performing the compression stroke injection stably in the vicinity of the stoichiometric air/fuel ratio, so that the exhaust cleaning performance can be improved and so that the output characteristics can be improved by executing the first operation mode.
    • 用于控制内燃机驱动的电子控制单元(40)在进行空/燃比反馈控制的同时执行用于在吸入冲程中喷射燃料的第一操作模式,当在介质/ 发动机的高负载驱动状态。 此外,响应于提高催化剂的温度的要求,第一操作模式切换到第二操作模式,其中在压缩冲程中喷射燃料,同时使空燃比反馈控制执行预定的空气/ 作为目标值的化学计量空燃比附近的燃料比。 此外,在切换到这些操作模式的每一个时,空燃比反馈的空燃比校正系数被增加/减小,以促进O2传感器(22)的输出转向点的偏移,从而 防止由于伴随着切换到每个操作模式的目标空气/燃料比的偏移而引起的空气/燃料比控制的这种不稳定性。 结果,在用于在理论空燃比附近稳定地进行压缩冲程喷射的第二操作模式中,排气净化催化剂(3)的温度升高,从而可以提高排气净化性能 可以通过执行第一操作模式来改善输出特性。
