Revetec made prototypes of engines for sports use, although they were also suggested for use in aviation. They are of original design in crankshaft terms. These engines are "trilobate" (three lobed) pieces, as we will see.

-All of them are in a prototype state at the beginning of the year 2006.

-Several prototypes have been made in various cylinder arrangements.

-We mention first the CCE 2003 model, with four horizontally-opposed cylinders and double ignition.
