00. Contents, Instructions, Terminology
00.1 Contents of the Manual
This Manual contains data and instructions for operation and mainte-
nance of the engine as well as instruction for handling, personal
protection and first aid when fuel-, lubricating oils and cooling water
additives are handled during normal operation and maintenance work.
Basic general knowledge has not been entered. Consequently,
it is assumed that the engine operation and maintenance staff is
well informed of the care of diesel engines.
Wärtsilä reserves for itself the right to minor alterations and
improvements owing to engine development without being
obliged to enter the corresponding changes in this Manual.
The diesel engines will be equipped as agreed upon in the sales
documents. No claim can be made on the basis of this Manual as
here are described also components not included in every delivery.
The system diagram plans (fuel, oil, cooling etc.) are just indica-
tive and thus do not cover all installations. See installation
specific system drawings for more details.
Exact engine build-up in all details is defined by the specification
number on the name plate located on the engine. In all correspon-
dence or when ordering spare parts, be careful to state
engine type, specification number and engine number.
This Manual is supplemented by the Spare Parts Catalogue
including sectional drawings or exterior views of all components
(partial assemblies).
00.2 General rules
1 Read the corresponding item carefully in this Manual
before any steps are taken.
2 Keep an engine log book for every engine.
3 Observe the utmost cleanliness and order at all main-
tenance work.
4 Before dismantling, check that all systems concerned are
drained or the pressure released. After dismantling, immedi-
ately cover holes for lubricating oil, fuel oil and air with tape,
plugs, clean cloth or the like.

5 When replacing a worn-out or damaged part provided
with an identification mark stating cylinder or bearing num-
ber, mark the new part with the same number on the same
spot. Every exchange should be entered in the engine log and
the reason should be clearly stated.
6 After reassembling, check that all screws and nuts are
tightened and locked, if necessary.
7 Check that all shields and covers are fully functional
and in place.
Note! Predictive maintenance is important when it comes to fire
protection. Regular inspection of fuel oil lines, lubricating oil
lines and connections must be done.
00.3 Terminology
The most important terms used in this manual are defined as
follows, see also Fig 00-1:
Operating side. The longitudinal side of the engine where the
operating devices are located (start and stop, instrument panel,
speed governor).
Rear side. The longitudinal side of the engine opposite the
manoeuvering side.
Driving end. The end of the engine where the flywheel is located.
Free end. The end opposite the driving end.
Designation of cylinders. According to ISO 1204 and DIN 6265
the designation of cylinders begins at the driving end. In a
V-engine the cylinders in the left bank, seen from the driving end,
are termed A1, A2 etc. and in the right bank B1, B2 etc., see below:

Designation of bearings.
·Main bearings. The shield bearing (nearest the flywheel) is No.
0, the first standard main bearing is No. 1, the second No. 2 etc.
·The thrust bearing rails are located at the shield bearing.
The outer rails close to the flywheel are marked with 00 and
the inner rails with 0.
·The camshaft bearings are designated as the main bearings,
the thrust bearing bushes being designated 00 (outer) and 0.
·Camshaft gear bearings. The bearing bushes are designated
00 (outer) and 0.
·Upper and lower bearings shells. In bearings where both the
shells are identical, the upper one is marked with “UP”.
Designation of bearings
Operating side and rear side. Details located at the operating
side may be marked with “M” (Manoeuvering) and correspond-
ingly “B” for the back of the engine (B-bank on a V-engine).
Clockwise rotating engine. When looking at the engine from
the driving end the shaft rotates clockwise.
Counter-clockwise rotating engine. When looking at the
engine from the driving end the shaft rotates counter-clockwise.
Bottom dead centre, abbreviated BDC, is the bottom turning
point of the piston in the cylinder.
Top dead centre, abbreviated TDC, is the top turning point of
the piston in the cylinder. TDC for every cylinder is marked on
the graduation of the flywheel. During a complete working cycle,
comprising in a four-stroke engine two crankshaft rotations, the
piston reaches TDC twice:

a) For the first time when the exhaust stroke of the previous
working cycle ends and the suction stroke of the following one
begins. Exhaust valves as well as inlet valves are then somewhat
open and scavenging takes place. If the crankshaft is turned to
and fro near this TDC, both exhaust and inlet valves will move,
a fact that indicates that the crankshaft is near the position which
can be named TDC at scavenging.
b) The second time is after the compression stroke and before the
working stroke. Slightly before this TDC the fuel injection takes
place (on an engine in operation) and this TDC can therefore be
defined TDC at firing. Characteristic is that all valves are closed
and do not move if the crankshaft is turned. When watching the
camshaft and the injection pump it is possible to note that the
pump tappet roller is on the lifting side of the fuel cam.
Marking of the flywheel. The flywheel is divided in 360°, starting
from TDC at firing for cylinder 1. TDC at firing for every cylinder
is marked on the flywheel. There is a common marking for the
cylinders in engines with even cylinder numbers, one cylinder is
at TDC at firing and the other is at TDC at scavenging. There are
separate scales for A- and B-bank in a V-engine. See also the firing
order in chapter 01. Firing interval, in crank angles, can be
determined by dividing 720° with the number of cylinder.
Example of reading the flywheel
Example: On a 12V32 engine, the fuel timing is read to 10° for
cylinder A2 when the flywheel is in the position shown in the above
figure.
