    摘要： A simple-design device for the measurement of coefficients of friction depending on the relative speed between a sample (8) and a brake disc (13) features a simple-design set-up and is well suited for the measurement of the changes of the coefficient of friction in the starting and in the stopping phases of the friction surface (13). The device operates by pressing the sample (8) with a defined pressing force (K1, K2) onto the friction surface (13) and simultaneously measures that force (K3) with which the samples (8) are dragged by the friction surface (13) transversely to the pressing force (K1, K2) as a function of time and speed. A brake disc can be provided as a friction surface (13). A single source of forces (K1, K2) for the pressing force can also be provided, resulting in a simple-design and sturdy structure for the device.

    摘要： A piston and method of construction are provided. The piston includes an upper crown having a combustion surface with an upper land depending therefrom and a lower crown having a pair of pin bosses that depend to a pair of laterally spaced, axially aligned pin bores. The upper crown is constructed as a monolithic piece of a first material having a thermal conductivity within a range of about 7 to 25 W/m-K. The lower crown is constructed from a low grade steel material having a thermal conductivity higher than the upper crown. The upper crown is joined directly to the lower crown, wherein the upper crown acts as a barrier to thermal conductivity and thus, the heat within a combustion chamber housing the piston for reciprocation therein is maintained and maximized.

    摘要： A piston particularly adapted for heavy-duty diesel engine applications is fabricated from separate parts having circumferentially extending joining surfaces that are heated prior to bonding to an elevated temperature sufficient to enable bonding of the joining surfaces, and thereafter the joining surfaces brought into contact with one another and twisted to attain a permanent metallurgical weld at the interface of the joining surfaces. The piston has radially spaced walls which are both welded simultaneously. The weld joints may lie in the same or different planes. Once joined, and while still hot, the parts may be pulled apart slightly to reduce the wall thicknesses at the weld joint.
