TURBOCHARGER SYSTEM SUBASSEMBLIES AND ASSOCIATED ASSEMBLY METHODS

摘要

A subassembly of a system including an exhaust gas turbocharger system coupled with an internal combustion engine exhaust system, comprises first and second components secured to each other, wherein the components are heated to an operational temperature by engine exhaust gases during engine operation. The components are secured to each other by or with a 'low-melt material', i.e., a material whose melting temperature is less than the operational temperature, such that the low-melt material melts or at least loses its securing and/or positioning functionality upon operation of the engine and turbocharger system, and thus no longer performs any fastening or positioning function for the components. In some embodiment, temporary fasteners made of or including the low-melt material are employed for temporarily securing and positioning the components.
