Efficient MAN D08 light-duty Diesel engines series for a wide range of applications

The use cases of light and medium-duty utility vehicles are various. MAN vehicles in the TGL and TGM classes (7.5 tonnes to 26 tonnes) are used both in long-distance and distribution operations, as well as in tractor units. The key focus of this development was therefore directed towards a high degree of modularity, whilst simultaneously providing an increased variability of the four and six-cylinder engines. Thereby it was possible to realize not only the already known existing option packages, such as a rear PTO on the flywheel housing or hydraulic pumps, but it also enabled to provide new equipment, like a preparation for retarder usage, a FRIGOBLOCK generator or an arctic package across all performance levels.To achieve this high level of modularity, variability and simplicity the basis of the emission concept of the new MAN D08 is SCR only. By omitting exhaust gas recirculation and thereby reducing the level of boost pressure that is required to operate the engine, it was possible to reconfigure the engine completely and to utilize single-stage turbocharging, without sacrificing performance. Due to the single stage turbocharging and exhaust after treatment concept, also the number of engine components and therefore the weight of the engine itself could be reduced significantly.
