    Abstract: A thin-walled double pipe exhaust manifold comprises a double pipe consisting of a comparatively thin inner tube and a comparatively thick outer tube, both spaced apart from each other adiabatically through an aperture defined between these tubes. The inner tube is formed with at least one bead portion for relieving thermal stresses induced in the inner tube. To effectively reduce thermal stresses by way of thermal expansion or contraction, the bead portion is provided around each heat spot similarly to the temperature distribution of each heat spot.

    Abstract: Longitudinal end portions of an elongated twenty-cylinder engine are disassembled to remove a cylinder location from each end of each cylinder bank for converting a crankcase from a twenty-cylinder, two-cycle, V-type diesel engine to a sixteen-cylinder configuration for use in a diesel electric locomotive. Peripheral air box access windows are provided at each longitudinal end of the crankcase. Portions of the exhaust deck, water jacket side wall and internal cylinder retainer support framing from the disassembled end portions are return welded to the remaining structure after separation of each endplate. Distal edges of longitudinally-extending remaining crankcase framework are machined to provide for receiving a new planar endplate of increased thickness gage at each end. Vibration and thermal stress-relief are applied before external surfaces of the new endplates are machined. The power deck for each cylinder bank is machined uniformly to relocate each camshaft with uniform downward displacement; the crankshaft relationship is predetermined accordingly, and openings for endplate support drive openings maintain their same angular and dimensional relationships to the camshafts and crankshaft.

    Abstract: A component subjected to zonally differential thermal stress for engines, machinery or other devices, in particular a component for combustion engines. In these components, in order to arrange more favourably the stress variation as a function of temperature in the thermally highly stressed parts or regions, so that the adjoining colder regions do not reduce or hinder its expansion, in the material of the component, for example a piston of a combustion engine, in the neighbourhood of the zones of higher thermal loading, at least one closed hollow chamber is provided which is completely filled with a substance which has a higher coefficient of thermal expansion than that of the material of the component surrouding the chamber.

    Abstract: The invention provides a cast part which is cast from a casting material and into which a channel is formed which gas flows through in operation, wherein the channel is at least in sections delimited by a separately prefabricated metal insert which is cast into the cast part. In order that such a cast part can withstand the highest thermal and mechanical stresses in the area of its gas-conveying channel, the invention proposes that the insert on its inner surface assigned to the gas and on its outer surface assigned to the casting material is in each case at least in sections coated in each case with a glaze or enamel coat.
