2.7.4 Fuel recommendation
The diesel fuel must meet the requirements of EN 590 and ASTM D975 respectively.
According to these standards a specific portion of bio diesel is permitted in the fuel.
Depending on the country of origin, bio diesel can be produced from different plant materials and
thus have different properties.
Affected by temperature, atmospheric oxygen and time, these bio diesel components in the fuel
may decompose in the fuel and thus cause damages within the fuel system.
The use of other fuels as well as the mixing with additives is only permitted after consultation
with the engine manufacturer.
2.7.5 Engine coolant recommendation
In fluid-cooled engines, the cooling fluid must be treated and monitored to prevent engine damage.
Water quality:
An important factor for treating the cooling fluid is the correct water quality.
As a rule, clear and clean fresh water, as soft as possible, complying with the following analysis
values must be used:

Tab. 38 Water quality specification
Contact the local water utilities for information regarding water quality. If the water does not meet
the parameters above, it must be treated.
If no suitable water is available, distilled or demineralised water shall be used for preparing the
coolant. Seawater, brackish water, brines and industrial wastewater are not suitable. Salts may
promote corrosion or disruptive deposits.
Coolant quality:
Within the scope of further technical development, new corrosion inhibitors/antifreeze have been
approved by the engine manufacturer.
