  • Patent number: 10119492
    Abstract: A fuel injection control unit (engine controller 100) performs a main injection (72) over a period ranging from a last stage of a compression stroke to an initial stage of an expansion stroke, and also performs a preceding injection (71), injecting a smaller amount of a fuel than the main injection, over a period ranging from an intake stroke to a first half of the compression stroke, and also determines whether or not the fuel injected by the preceding injection causes a partial oxidation reaction during a second half of the compression stroke, and on determining that the fuel causes the partial oxidation reaction, performs a middle-stage injection (73). The middle-stage injection is performed at such a timing that allows the fuel injected by the middle-stage injection to ignite spontaneously on or after the fuel injected by the main injection has spontaneously ignited and before the partial oxidation reaction occurs.
