The Miniature Internal Combustion Engine (MICE) is otherwise known more commonly known today as a model engine. Although the name has seemed to change the overall concept and design of this type of engine has remained the same thus making it a true MICE. The miniature internal combustion engine in many ways is a copy or model that represents and reproduces regular or standard size true operating and functional internal combustion engine but in a reduced state; on a small scale or in a greatly reduced size. All miniature internal combustion engines follow the same operating principles and behavioral properties as their standard or regular size prototypes; but is done so primarily at reduced sizes and pressures. One main but very important difference that seems to distinguish a MICE between a ICE (internal combustion engine) from which the MICE design was patented on is that the air fuel mixture passes through a hollow crankshaft unlike the ICE which utilizes passageways from the crankcase leading eventually above the piston to finalize the ignition process. This particular design would most likely be a two stroke ICE were a four stroke ICE would use valves to lead its fuel air mixture to its final destination above the piston.
