RM 103.74

As a part of my newest ultimate engine display, the 4-stroke Diesel engine is one of the most common Diesel engines!

This cutaway-style model shows how a 4-stroke Diesel engine works, and features many important parts:

  • Moving valves, and cams
  • Fuel injector, and mechanical pump
  • Moving turbo compressor
  • Light brick, simulating combustion

Plus a mechanical stroke indicator that switches based on what stroke the engine is currently in!

With 918* parts, this MOC will stand out in any collection!

Over 202 pages, and over 380 steps!

Files are in a .ZIP folder. Once extracted, there are three files: PDF instructions, a Bricklink .XML file, and a video detailing how to upload the .XML file to a Bricklink Wanted List.


Only the stroke indicator and nameplates are included. No other parts are included with the purchase of this product.
