Background
| Eaton
has been mass producing helical roots type superchargers for
automobiles since 1989 when Ford requested a supercharger for
their Thunderbird SC. Today Eaton superchargers are used in
a variety of applications, including vehicles by General Motors,
Ford, and Nissan. |
| We obtained
two Eaton superchargers, a second generation M62 and a third
generation M90. Some aspects of the superchargers vary between
applications, including the mating surface between the supercharger
and engine block, the length of the snout, and the configuration
of the throttle body inlet. Our examples are specific to General
Motors applications, namely the 1995 and 1997 L67 engines respectively.
Please see Appendix A for specifications on these two superchargers. |
(Eaton MP90, CAPA) |
Our
objective was to generate 1mm or better accuracy CAD models
of the two superchargers using SDRC I-DEAS computer aided design
software. These superchargers have multiple parts which we planned
to assemble and animate using the software package. The final
goal was to perform a thermal analysis of the two housings,
find the likely routes of heat flow from the engine block, and
suggest methods to keep the housing cool.
