Wiseman engine
Biloxi, MS
in development

Wiseman Technologies is marketing a unique engine
that is more efficient than conventional piston types.
Both two and four stroke prototypes have been built
and tested, and a diesel version is under development.
This internal combustion engine utilizes special gear
that allows the crankshaft to operate in an entirely
linear movement and thus reducing friction. Because of
its weight and efficiency, it could have implications for
the UAV industry.
