Abstract: An imbedded control system is disclosed for use with an engine having a cylinder liner and a seal. The control system may have at least one sensor configured to generate a signal indicative of a combustion process occurring inside the cylinder liner, and a controller in communication with the sensor. The controller may be configured to determine an amount of heat generated inside the cylinder liner based on the signal and a combustion model of the engine, to determine a heat flux through the engine based on the amount of heat and a heat flux model of the engine, and to determine a temperature at the seal based on the heat flux and a thermal model of the cylinder liner. The controller may also be configured to track a time at the temperature, and to determine a damage count of the seal based on the time at the temperature.

Abstract: A composition for additive manufacturing is provided. The composition comprises a solvent and a rubber dissolved in the solvent, wherein the ratio of rubber to solvent is in a range of 1:10 to 3:5. A method of manufacturing an object is also provided. The method includes forming a first layer of the object by dispensing a printable composition comprising rubber dissolved in a solvent, in a ratio of 1:10 to 3:5 allowing at least a portion of the solvent in the first layer to evaporate, adding a second layer to the first layer by dispending a printable composition comprising a rubber dissolved in a solvent in a ratio of 1:10 to 3:5 and allowing at least a portion of the solvent in the second layer to evaporate.

Abstract: A seal assembly that includes a substantially annular cylindrical configuration that defines an aperture that defines a cylindrical axis and a radial direction is provided. The seal assembly comprises a spring member that includes two arm portions that extend substantially in a direction that is parallel to the cylindrical axis and that meet forming a flex point, and a sealing member that at least partially encapsulates the spring member and that includes: a first sealing feature, and a second sealing feature that is positioned axially and radially adjacent the flex point of the spring member and that faces in a direction that is diametrically opposite the direction that the first sealing feature faces along the radial direction, and an elastomeric material that includes a base resistant type 5 fluoroleastomer made from a copolymer of propylene and tetrafluoroethylene.

Abstract: A system for determining diameter of a seal is provided. The system includes a frame. The system includes a first member mounted on the frame. The first member includes a first surface configured to receive a portion of the seal thereon. The system includes a hub movably mounted on the frame. The system includes a second member mounted on the hub. The second member includes a second surface configured to receive another portion of the seal thereon. The seal is removably disposed around the first and second members. The second member is moved with respect to the first member to retain the circular member in a tensioned configuration. The system includes a measuring device disposed on the frame. The measuring device is configured to measure a distance between the first member and the second member to determine the diameter of the seal.

Abstract: A method for testing a performance of a plurality of sealing members includes providing a testing fixture including at least two blocks in a contacting relationship with a plurality of fixtures. Each of the plurality of fixtures defines a groove portion for receiving a sealing member. The method further includes connecting each of the plurality of fixtures with a fluid manifold. The method also includes controlling a temperature of each of the at least two blocks and the groove portion using a thermal device. Each of the at least two blocks and the groove portions are at temperatures different from each other. The method also includes passing a fluid through each of the plurality of fixtures so as to flow through a channel provided adjacent to and surrounding the groove portion. The method further includes monitoring a response of the sealing members to determine at least one performance parameter.

Abstract: An idler wheel assembly for a track-type machine includes a circular body. The circular body includes a central hub portion, an annular flange portion integral with the central hub portion, and a circumferential rim portion to define an annular cavity along with the central hub portion and the annular flange portion. A sound dampening coating provided on the circular body.
