MAN diesel engines - Technical data

A well-known example is the MAN D2842 engine. The designation can be decoded as follows: “28” stands for the bore diameter, which equals 128 mm (by adding 100 to the type number). The “4” stands for the stroke – calculated by multiplying the type number by 10 and then adding 100 – resulting in 140 mm. The “2” indicates the number of cylinders – in this case, 12. Different numbers of cylinders result in varying performance characteristics and application areas.

The importance of engine mounts

Engine mounts play an important role in securing the engine to the chassis while absorbing vibrations and shocks during operation. High-quality mounts help reduce noise, improve ride comfort and protect surrounding components from excessive wear. Worn or damaged engine mounts can lead to misalignment, increased vibration, and even damage to other parts, so timely replacement is essential for maintaining performance and reliability.
