LEGO Educational Engines

A LEGO Educational engine displays the mechanisms of engines for the purpose of educating the viewer about how engines work. They often do not run under their own power (may use LEGO Power Functions, etc. to turn) and feature transparent or cutaway sections.

Notable example of educational engine models have appeared on the LEGO Ideas platform and are often constructed with the intent of making each component of the engine look and mechanically move similarly to how a real steam or internal combustion engine does.
