The M 25 C, part of the MaK long-stroke engine generation, is based on the proven design characteristics of the M 20 C, M 32 C and M 43 C engine series. In the development of this new engine generation, the objective was to achieve a high benefit level for the customer. In all design and development considera- tions, therefore, three criteria had maximum priority-reliability, economy and environmental compatibility. Other important points of great significance in the engine's design and development work were ease of maintenance, long maintenance intervals, long component life and ease of instal-...

All MaK engine series have the same nomenclature with the design status “C”. The power output of the M 25 C increased slightly. The engine development also considers a possible Caterpillar Common Rail introduction. The design changes of the new M 25 C cylinder block result in an improved way of founding with an increased dimensional accuracy. The new governor drive is of simple and robust design. The design...
