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 cylindersCylinders are the individual power units of an engine that work together to generate energy. More cylinders mean greater output and faster acceleration. In addition, systems with more cylinders generally operate more smoothly than those with fewer – a clear advantage in operation and performance. Therefore, it’s essential to ensure the correct number of cylinders to achieve the desired power output.
