Suspended installation of more than 500 parts from a Cummins NTC‑400 Big Cam III diesel engine

Cummins Corporate Headquarters and Museum

A complex diesel engine becomes a three‑dimensional diagram as more than 500 parts are suspended in space. The installation celebrates engineering clarity and turns industrial design into an object of wonder.

Rudolph de Harak (1924–2002) was a modernist designer who brought precision and legibility to graphics and environments; his collaboration with Cummins exemplifies design as visual communication.
