  • Patent number: 11024476
    Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, a transmission mechanism, a movement regulating portion, a contact mechanism, and a first biasing portion. The movement regulating portion enables movement of a lever body to a second position when an end of the operation unit on a housing portion side is positioned at an initial position, and disables movement of the lever body to the second position when the end of the operation unit on the housing portion side is positioned closer to an operation surface than the initial position in a movable direction. The first biasing portion biases the plunger from an operating position toward a return position.

  • Patent number: 11008970
    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.

  • Patent number: 11011325
    Abstract: A push button switch may include a housing, an operation unit, and, a lock lever unit. A lever body of the lock lever unit may have a locking portion capable of locking one end of a long jig in an extending direction. The housing may have a fulcrum projection that contacts an intermediate portion of the jig having the one end locked to a locking portion when the lever body is moved using the jig, and serves as a rotation fulcrum of the jig.

  • Patent number: 11002215
    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.

  • Patent number: 10910174
    Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, and a biasing portion.

  • Patent number: 10876490
    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.

  • Patent number: 10612474
    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.
