Engine type classification
5
All the engines dealt with here are related in terms of their design and make up a family.
The type classification, which is made up of a series of letters and numbers, reveals some of the features
of the engine in question provided the reader is familiar with the underlying nomenclature.
We will explain the system using model D 2866 LUE 602 / 605:
D The “D” at the start of the type classification stands for “diesel”.
28 The numbers “28” indicates that the power plant in question has a bore of 128 mm.
6 The “6” means 160 mm stroke. This figure is, however, only approximate for this model.
The actual stroke is 155 mm.
6 The “6” indicates the number of cylinders 6
L This letter stands for “charge-air cooling” (German: Ladeluftkühlung)
U The “U” stands for “Underfloor”
E The “E” stands for “fitted engine” (German: Einbaumotor) and is intended to distinguish MAN
vehicle engines
