    摘要: A control apparatus for a direct-injection, spark-ignition engine including a temperature-condition detector for detecting a temperature condition of the engine catalyst, and a controller for controlling a fuel-injection operation. The controller controls the fuel injector to perform divided fuel injections of at least a leading fuel injection and a trailing fuel injection during a compression stroke prior to the ignition timing based upon a detection of the temperature condition in an inactivated state of the catalyst, the trailing fuel injection being performed at such a timing that its mixture concentrates adjacent to the spark plug at the ignition timing by way of high cylinder pressure during a late-stage of the compression stroke, the leading fuel injection being performed at such a timing that its mixture distributes around a mixture layer by the trailing fuel injection at the ignition timing, and a midpoint between an initiation of the leading fuel injection and an initiation of the trailing fuel injection being positioned within a period during a latter half of a compression stroke.

    摘要: A control device for a direct injection engine having a catalyst provided in an exhaust passage for converting exhaust gases and an injector for injecting fuel directly into a combustion chamber, includes a temperature state identifier for judging the temperature state of the catalyst, a load condition detector for sensing engine load conditions, and a fuel injection controller for controlling fuel injection from the injector. The fuel injection controller performs quick light-off control operation by causing the injector to inject fuel in one-time injection mode during a compression stroke in a specific low-load operating range of the engine when the catalyst is in its unheated state where its temperature is below its activation temperature, and switching the mode of fuel injection to intake-compression stroke split injection mode in a specific high-load operating range of the engine.

    摘要: A line head type liquid discharge apparatus includes a treatment liquid applying device, a first discharging device, a heating device, and a second discharging device. The treatment liquid applying device applies a treatment liquid to a non-permeable base material. The first discharging device discharges a first ink containing an organic solvent onto the non-permeable base material to which the treatment liquid has been applied. The heating device heats, with an infrared ray, the non-permeable base material onto which the first ink has been discharged. The second discharging device discharges a second ink containing an organic solvent onto the non-permeable base material heated by the heating device. A content ratio of the organic solvent contained in the first ink is higher than a content ratio of the organic solvent contained in the second ink.
