Fuel injection valve

The fuel valve is uncooled and placed in a sleeve in
the centre of the cylinder head.
O-rings around the fuel valve body prevent fuel and
lubricating oil from mixing. From the side of the cyl-
inder head, a lance for fuel supply is screwed into
the fuel valve (L16/24 is mounted by means of 3
leaf springs). The lance is sealed with a bushing and
two o-rings where the lance goes into the cylinder
head. A double-walled high pressure pipe connects
the fuel pump with the lance.
Leak oil from the fuel valve or from a possible
defective high pressure pipe is led to the bore for
the lance in the cylinder head. From here a pipe will
drain the fuel to the leakage alarm and further to the
leak oil connection. From here the HFO can be led
to leak oil tank and MDO/MGO to the day tank.
