    摘要: A fuel rail assembly of an internal combustion engine includes an axially extending non-round fuel conduit and at least one axially extending stiffening feature integral with said conduit. Integration of the stiffening features in the conduit enables reduction or elimination of the objectionable frequency noise radiated by the fuel rail assembly. By aligning the stiffening features axially relative to the conduit, panels having a relatively small surface area are formed and, thus, the noise radiating surface area is significantly reduced. The axial orientation of the added stiffening features allows the length of the stiffening features to be relatively large, which increases the stiffening effects to provide increased resistance to flexing, thus, reducing the noise radiated by the fuel system of the internal combustion engine.

    摘要: An analog angle encoder having a simply constructed magnet assembly, wherein rotation of a magnetic field relative to a magnetosensitive device provides a varying output of the magnetosensitive device that varies sinusoidally with the angle of relative rotation. The simply constructed magnet assembly is of a closed-path geometry composed of a single piece of magnetic material wherein only a first portion thereof is magnetized for providing the aforesaid magnetic field for the sensor. The remaining portion of the magnet material (the second portion) remains unmagnetized and does not substantially influence the magnetic field produced by the first portion any more than, for example, air would cause.

    摘要: A target wheel sensor assembly includes a sensor that is placed near a target wheel. The sensor includes a magnet to create a flux and a sensing element to sense changes in the flux as the target wheel rotates. The target wheel is alternatingly formed with multiple teeth and multiple slots. Each tooth includes a flat portion that is parallel to the bottom of the sensor and a chamfered portion contiguous to the flat portion. The chamfered portion forms an angle, &agr;, with the bottom of the sensor. As the target wheel rotates, the shape of the teeth in conjunction with the slots cause the sensor to output an asymmetric signal. The shape of the signal is used to determine the direction of motion of the target wheel.
