Notes:
In recent years, there is an effort to develop a portable, autonomous micro powergeneration system to obtain an order of magnitude improvement in energy density over generalalkaline or lithium ion batteries. As hydrocarbon fuels have much higher energy to weight ratiosthan general batteries, researches to realize micro-engines fueled by such hydrocarbon fuels arecarried out in some universities or institutes. The first key problem of the researches is how to get amicro-engine structure suitable for MEMS (Micro-Electro Mechanical Systems) fabrication. Thismicro-engine structure needs characteristics such as planar geometry, self-valving operation and aminimal number of moving parts and so on. In this paper, a micro sliding rotary type combustionengine structure is presented and described. The intrinsic characteristics of the engine housing curvenamed of “kindred cardioids curve” are described in details. The structural scheme and cycleprocess of the micro-engine are discussed. Some performance parameters of the micro engine aretheoretically calculated with H2-Air mixture and specified geometry parameters. The primitivecalculated results indicate that the sliding rotary combustion engine is workable and effective
