Single grade cylinder
lubricating oil application
In case the engine is specified for operation on liquid fuel with a sulphur content
of up to 0.10 % m/m sulphur (ultra low sulphur), then it is in any case sufficient
to install a single low BN cylinder lubricating oil tank and consequently, no
changeover device is required. The same is valid, if a single grade cylinder lubri-
cating oil, typically in the BN 40 to 60 range, which is capable and approved of
for handling both modes, gas and diesel mode operation.
Figure 4-18 Cylinder lubricating oil system for fuel with ultra low sulphur content
(maximum 0.10 % m/m sulphur) or alternatively, a single grade cylinder lu-
bricating oil is applied for fuel with very low sulphur content (maximum
0.50 % m/m sulphur)
Service tank and storage tank
The arrangement of service tank and storage tank can be changed by locating the
storage tank in place of the service tank. If this arrangement is preferred, the
storage tank must be placed at the same height as the service tank to provide the
necessary head. Furthermore, the storage tank must be of similar design, with a
sloping floor.
Electrical trace heating for system side cylinder lubricating oil piping
To ensure the correct cylinder lubricating oil temperature at engine inlet
(40+10/-5°C), electrical trace heating is recommended to be applied. The ME
provides cabinet control box E86 for heating cable connection and power supply.
The heating cable together with the plug can be directly ordered from the engine
maker. The guided heating cable length is determined by the cylinder LO pipe
length and the engine type (see Table 4-3,  4-31).
