Abstract: A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism integrates a deposition amount of deposits per unit time, and estimates a deposition amount of deposits on an injection hole of the fuel injection valve. The controller causes the fuel pressure adjustment mechanism to increase a fuel pressure, when the estimated deposition amount exceeds a predetermined value, and corrects the unit deposition amount acquired by the deposition amount estimation according to the set fuel injection timing of the fuel injection valve. The controller corrects such that as compared with the unit deposition amount when the fuel injection timing is set to a first timing away from a top dead center of the piston by a first period, the unit deposition amount decreases when the fuel injection timing is set to a second timing away by a second period longer than the first period.

Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism sets an air-fuel ratio of a fuel-air mixture to be generated within a combustion chamber to be equal to or leaner than a theoretical air-fuel ratio, based on an operating condition of an engine; drives the fuel injection valve, based on the set air-fuel ratio; estimates a deposition amount of deposits on an injection hole of the fuel injection valve, based on an operating condition of the engine; causes the fuel pressure adjustment mechanism to increase the fuel pressure, when the estimated deposition amount of deposits exceeds a predetermined value; and restricts the fuel pressure from increasing, even when the estimated deposition amount of deposits exceeds the predetermined value, as long as the fuel-air ratio is set to an air-fuel ratio leaner than the theoretical fuel-air ratio.

Abstract: An inkjet printing apparatus includes: a roller configured to rotate in synchronization with the print medium being conveyed; an encoder configured to output a pulse signal depending on a rotation angle of the roller; and a controller. The controller is configured to: perform an off-center information obtaining processing of driving the inkjet head to print a test pattern including dots arranged in a conveyance direction of the print medium and calculating an off-center information of the roller based on positions of the dots in the printed test pattern; and in the printing operation, correct the ejection timing of the ink by the inkjet head determined based on the pulse signal outputted from the encoder, based on the off-center information calculated in the off-center information obtaining processing.

Abstract: Disclosed is a control device for a multi-cylinder engine having a combustion chamber (19) to which an intake port (16) and an exhaust port (17) are connected. The control device comprises: an intake-side variable valve operating mechanism (71) for controlling a lift timing of two intake valves (21a, 21b) of the intake port (16); an exhaust-side variable valve operating mechanism (72) for controlling a lift timing of an exhaust valve (22a); and an exhaust-side valve operating mechanism (73) for driving an exhaust valve (22b) at a fixed timing. The control device is operable, when executing cylinder deactivation in a low engine load and low engine speed operating range, to cause the exhaust-side variable valve operating mechanism (72) to open the exhaust valve (22a) during downward movement of a piston (14) in a cylinder (18) being subjected to the cylinder deactivation.
