    摘要: 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).

    摘要: 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.
