5.1.4 Monoblock column
The monoblock column is the middle part of the engine. The monoblock column is installed on
the bedplate and holds the cylinders.
On the exhaust side (ES) the monoblock column has one relief valve (001, Figure 5-4) per
cylinder. The relief valves open, if the pressure in the monoblock increases too much.
On the fuel side (FS) the monoblock column has one door (002) per cylinder. During normal
operation the doors are closed and locked. For maintenance or inspection work the doors can
be opened. Obey the safety rules before you open the doors.
The length of the monoblock column is related to the number of cylinders.
