Abstract: | This papa-presents an ongoing project of developing a micro reciprocating internal combustion engine. The engine is
designed on the basis of a hvo stroke piston engine, but heavy modifications have been made to suit the 2D MEMS
fabrication. All the engine parts are located in two layers. Piston seals are not used and leakage is prevented by the
introduction ofmicrogrooves on the piston, tight tolerance control and an extended contact area hehveen the piston and
the cylinder. With the assistance of a film of lubrication oil, these measures prove effective in preventing leakage. A new
approach has been developed to fabricate high temperature resistant engine components at low cost. The approach
relies on the UltraThick SU-8 Process (UTSP) to make micromoulds: then ceramic and metallic engine components can
be produced based on the moulds. The UTSP is a UV lithography process for producing up to 1000 ?m thick SU-8 layers
and the quality of the fabrication results can be compared with those made by using X ray exposure process in the same
Ihichiess. A complete microengine has been fabricated in SU-8 using the UTSP for test drive. High quality ceramic and
metallic components have been produced based on the SU-8 moulds, proving the new approach is feasible for {wilding
durable micro hot engines at a low cost. |
