Abstract: Additive manufacturing creates, repairs, or upgrades parts. Conventional manufacturing processes are used to prepare a body of the part and additive manufacturing processes are used to prepare intricate geometries of the part. A support structure is used to support the intricate features during the additive manufacturing processes. Particularly, laser sintering is used to create entire parts or to create a repaired or upgraded part by casting the body of the part and integrating the body with a build plate and using laser sintering to develop the intricate features necessary.

Abstract: A method for repairing a cylinder liner includes: placing a cylinder liner having a first inner diameter and a first outer diameter into a cavity of a confinement, the cavity including a cavity inner diameter that is substantially the same as the first outer diameter of the cylinder liner; heating the cylinder liner to a temperature at which the cylinder liner undergoes plastic deformation, causing the first inner diameter of the cylinder liner to decrease; and cooling the cylinder liner. The cooled cylinder liner has a second inner diameter that is less than the first inner diameter. An apparatus for repairing a cylinder liner includes a confinement having a cavity and a fluid passageway for controlling the temperature of the confinement, and a heating block for heating the cylinder liner when the cylinder liner is inserted into the cavity.

Abstract: A cylinder liner is provided that can prevent a band seal from being damaged during installation. The cylinder liner includes a pilot portion having a larger outer diameter than an outer diameter of the band seal. The pilot portion contacts an insert and a seal positioned on a recess of the engine block so that the cylinder liner lateral movement during operation of the engine block is prevented. In order to accommodate a larger outer diameter of the pilot portion, the inner diameters of the seal and insert can be correspondingly increased through a machining process. The machining process also creates uniform inner diameters of the seal and insert.

Abstract translation: 提供了可以防止带状密封件在安装过程中损坏的气缸套。 气缸套包括具有比带密封的外径更大的外径的先导部分。 先导部分接触插入件和位于发动机缸体的凹部上的密封件，从而防止发动机缸体运行期间气缸套横向移动。 为了适应导向部分的较大的外径，通过机械加工可以相应地增加密封件和插入件的内径。 加工过程也产生了均匀的密封和插入内径。
