Engine type classification All the engines dealt with here are related by design and together form a family. The sequence of letters and numbers which make up the model designation reveal a number of character- istic properties of the engine in question to those familiar with the basic nomenclature. We will explain the system using model D 2842 LE 201 as an example: D The “D” at the beginning of the model designation stands for “Diesel” 28 The number “28” indicates that the engine has a 1 28 mm bore 4 The “4” means 1 4 2 mm stroke 2 The “2” shows that the engine has 12 cylinders.
If there is a 0 here instead, the engine is a 10-cylinder model L This letter stands for the German word “Ladeluftkьhlung”, meaning “intercooling” E “E” stands for the German word “Einbaumotor”, meaning “installation engine” , and distinguishes these engines from MAN vehicle engines 201/2.. This is a Works internal development number. This engine generation was introduced early 1994 with modified turbocharger, high-pressure injection and, fitted as standard, an electronically con- trolled quantity regulator. 6
