    • PROBLEM TO BE SOLVED: To accurately detect pre-ignition without being affected by seating of fuel injection valve.SOLUTION: An ECU 50 detects a state where pre-ignition is likely to occur as a state to be monitored, on the basis of history data of an operation region and a crank angle. When the state to be monitored is detected, a fuel injection period is limited so that the fuel injection periods of fuel injection valves 26 and 28 in an individual cylinder are not overlapped with the second half of a compression stroke of another cylinder. Specifically, in multi-injection control, the number of times and/or intervals of the divided injection are reduced, and it is limited so that the divided injection of the plurality of times is completed until the second half of the compression stroke of the other cylinder. Accordingly, upon the occurrence of pre-ignition, the fuel injection valves 26 and 28 are prevented from being seated, and the pre-ignition can be accurately detected on the basis of an output of a vibration sensor 44.
    • 要解决的问题:准确检测预燃点,不受燃油喷射阀座的影响。 解决方案:ECU50基于操作区域和曲柄角度的历史数据来检测可能发生预点火的状态作为要监视的状态。 当检测到要监视的状态时,限制燃料喷射周期,使得单个气缸中的燃料喷射阀26和28的燃料喷射周期不与另一个气缸的压缩行程的后半部重叠。 具体而言,在多次喷射控制中,分割喷射的次数和/或间隔减少,并且被限制,使得多次的分割喷射完成,直到另一个的压缩冲程的后半部分 圆筒。 因此,在发生预点火时,防止了燃料喷射阀26,28的就座,并且可以基于振动传感器44的输出来准确地检测出点火。
