Toroidal engine that is also known as MYT or Massive Yet Tiny.

"The MYT Angel Labs engine"

-In 2006 this engine was presented by its inventor R. Morgado. His engine creates 32 combustion chambers. With only 14 inches in diameter, about 75 Kgs. of weight and the incredible power that is the same as of an engine with a displacement of 850 cubic inches.

-From the outside it looks like a "barrel" type engine.  It consists of two main parts: One is a toroidal cylinder with its oscillating pistons inside and the other part the connecting rod assembly.

-Because there are formed multiple combustion chambers and effective strokes, the power is high taken in account their relatively small size.

"Compairing"

-Morgado is proud of his engine when comparing it with another classic 850 cu in  Cummins truck engine.
