  • Patent number: 10344886
    Abstract: A method is proposed for operating a metering valve which is realized as a solenoid valve which is actuated by an electromagnet that interacts with an armature which is connected fixedly to a valve needle and, furthermore, is loaded with a pulse-width modulated metering signal which defines the metering of a reagent which is to be introduced into the exhaust-gas region of an internal combustion engine or of a preliminary stage of a reagent, as is an apparatus for carrying out the method. The opening duration of the metering valve is limited to a minimum opening duration, for which the metering valve is opened completely and which is fixed in such a way that a spray mist is always produced during the metering. The procedure according to this invention prevents the reagent from crystallizing and, as a result, firstly ensures exact metering of the reagent and secondly counteracts clogging of the metering valve, in particular if a urea/water solution is provided as preliminary stage of the reagent.

  • Patent number: 9046067
    Abstract: A fuel injector has the ability to inject two fuels that differ in at least one of pressure, chemical identity and matter phase, such as liquid diesel fuel and nature gas. A first direct operated check includes a closing hydraulic surface exposed to fluid pressure in a first control chamber, and is normally biased toward a closed position by a first spring. A second direct operated check has a closing hydraulic surface exposed to fluid pressure in a second control chamber, and is biased toward a closed position with a second spring. The first spring and the second spring are located on opposite sides of a plane oriented perpendicular to a long axis of the injector body, in part to satisfy packaging constraints when the direct operated checks are arranged in a side by side parallel configuration.

  • Patent number: 7819344
    Abstract: An injector used for an internal combustion engine includes a valve needle which closes a fuel passage by contacting a valve seat and opens the fuel passage by separating from the valve seat. A coil and a magnetic core are provided to drive the valve needle, and an anchor is held in a relatively displaceable state with respect to the valve needle. A first biasing device biases the valve needle in a direction opposite to a direction of a drive force, and a second biasing device biases the anchor in the direction of the drive force with a set load smaller than that of the first biasing device. A restricting feature restricts relative displacement of the anchor with respect to the valve needle in the direction of the drive force.

  • Patent number: 7093769
    Abstract: In a dynamic flow rate adjusting method, a press-fitting degree of an adjusting pipe is adjusted to regulate a load applied to a needle by a spring in a direction for closing an injection hole. Thus, a dynamic injection quantity of an injector is adjusted. An injection command signal having one-minute long pulse width is applied to the injector to measure a static flow rate, from which the press-fitting degree is calculated. Thus, the press-fitting degree, in which variation in the static flow rate is taken into consideration, can be calculated. Therefore, variation in the dynamic flow rate of each injector, which is calculated from the press-fitting degree, includes only a dynamic flow rate error, while a static flow rate error is eliminated from the variation in the dynamic flow rate.

  • Patent number: 6959878
    Abstract: A compact fuel injection nozzle includes a unitary nozzle body, a nozzle cap, a valve member and a spring sub assembly. The spring sub assembly provides a biasing force against a valve member that includes an integral lift stop. The biasing force holds the nose of the valve member against the valve seat of the nozzle body until the fuel pressure inside the injector exceeds a minimum opening pressure. The lift stop provides a stop limit, permitting the valve member to move away from the valve seat a predetermined axial distance. The minimum opening pressure and valve opening axial distance may be calibrated by selection and installation of shims.
