Engine-X is a free interactive 3D atlas of real machines. You can rotate each machine, explode it into its parts, cut it in section, switch on X-ray mode and watch it run with true kinematic motion, right in your browser.

Yes. The atlas, the machine guides and the 3D model downloads are free. There is no app to install and no account to create.

Ten machines so far: a turbocharger, a centrifugal pump, a V-belt pulley drive, a helical gear reducer, a planetary gearbox, a reciprocating air compressor, a plate heat exchanger, an inline-6 marine diesel engine, a turbofan jet engine and a gate valve, with more added regularly.

Yes. Every machine can be downloaded as GLB or STL, with each part available on its own, under the CC BY-NC 4.0 licence with credit to Engine-X. On a phone you can also place the model in augmented reality (AR).

Mechanical engineering students, ITI and diploma learners, teachers and trainers, marine and plant engineers, and anyone curious about how machines work inside.

Engine-X is built by Parth Parmar, a mechanical engineer from Jamnagar, India, who models every machine part by part.
