The Motor 250/400 is the first functional diesel engine. It was designed by Rudolf Diesel, and drawn by Imanuel Lauster. The workshop of the Maschinenfabrik Augsburg built two units, the A-Motor, and the B-Motor. The latter has been on static display at the Deutsches Museum in Munich since testing it came to an end. Throughout the late 1890s, several licensed copies of the Motor 250/400 were made. Most of these copies were very unreliable, which almost caused the diesel engine's demise.
