    Abstract: In a fuel injection valve used for an internal combustion engine, a valve closing lag time due to fluid resistance in a fuel path is shortened to decrease a minimum injection limit. More specifically, in the fuel injection valve in which an anchor is attracted to an end face part of a stationary core having a fuel path formed at a center part thereof by means of electromagnetic force, and in which a fuel injection hole is opened and closed by controlling a valve disc driven in conjunction with the anchor, there are provided a fuel reservoir part at a center part of an upper end face part of the anchor, a through hole extending axially in a fashion that an end part thereof is open to the fuel reservoir part, and a fuel path extending radially outward from the fuel reservoir part so that fuel is fed to a magnetic attraction gap between an upper end face part of the anchor and a lower end face part of the stationary core. Further, an opening part of a through hole that is open to an upper end face part of the anchor is at least partially opposed to a fuel introduction bore formed in the stationary core, and on the opening part of the through hole, a fuel introduction part is provided for capturing fuel running radially outward from a center side part of the anchor and for guiding the fuel thus captured to the through hole.

    Abstract: An electromagnetic fuel injection valve device for an internal combustion engine is configured to carry out an energization to an electromagnetic coil of an injection valve actuator for a valve opening motion and additionally carry out a mid-term energization at a time interval between both an energization for valve opening of a previous fuel injection and an energization for valve opening of a subsequent fuel injection. A current of the mid-term energization is smaller than a current of the energization for valve opening motion and has the same direction as a direction of the current of the energization for valve opening motion.

    Abstract: An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.

    Abstract: An electrically-controlled throttle valve apparatus includes a motor, a speed reducing mechanism for reducing rotation speed transmitted from the motor, a throttle valve connected to the speed reducing mechanism, and a force applying device applying force to the throttle valve in the direction of returning the valve to its initial position and adjusting the opening of the throttle valve by driving the motor. Parameters of the motor, the speed reducing mechanism, and the force applying device have values such that the operation time t from the minimum to the maximum throttle valve opening, which is determined by an evaluation equation obtained from equations of throttle valve motion, is less than a prescribed target throttle valve operation time t*. Furthermore, resistance and an induction voltage constant of the motor are determined to satisfy a constraint equation obtained based on Ohm's law.

    Abstract: In a fuel injection valve, it is intended to enhance valve-closing responsivity while maintaining durability (anti wear property) of a collision portion between a stationary core and a movable core and valve-opening responsivity.An annular end face 106A of the movable core 106 in the fuel injection valve is provided with a collision portion 106C that collides to a stationary core 107 when the movable core is magnetically attracted toward the stationary core side and a non-collision portion that keeps a fluid gap between both cores at an area of an outer side or an inner side from the collision portion. The annular end faces of the stationary core and the movable core are coated with platings 30, 31 having anti wear property, and at least one of the platings of the stationary core and the movable core is formed in such a manner that the thickness thereof at the collision portion 106C is to be thicker and the thickness thereof at the non-collision portion is to be thinner.
