Technical description

Engine

These engines are four-stroke, straight six marine diesel engines with overhead valves. They are fluid-cooled
and equipped with turbochargers. The inlet air to the engine is cooled by a seawater-cooled charge air cooler
(CAC) after compression in the turbo.

The engines have piston cooling (oil-cooled pistons). The lubrication system has a full flow oil filter, and the
TAMD63, TAMD73 and TAMD74 engines also have a partial flow (by-pass) filter. This by-pass filter is an
accessory on the TAMD71 engines.

The cooling system is divided into a freshwater and a seawater system. The seawater cools the freshwater
system via a heat exchanger (TAMD71 has double heat exchangers).

Cylinder heads

The engines have two cylinder heads, each of which
covers three cylinders. A special alloy cast iron
material is used for the cylinder heads. The cylinder
head gaskets are made of solid sheet steel and have
special rubber sealing rings inside for oil and coolant
channels.

The journal at the front of the crankshaft has been
ground to a polygonal shape. A polygon joint can
withstand the stresses from the vibration damper
(extra pulley or disengageable clutch) considerably
better than a keyed joint.

Piston cooling

Valve system

The camshaft is journalled in seven bearings and is
driven by the timing gears. The camshaft actuates
the inlet and outlet valves in the cylinder heads via
lifters, push rods and rockers.

In the TAMD71, TAMD73 and TAMD74, these valves
have double valve springs.

Cylinder block

The cylinder block is made of special alloy cast iron
and cast in one piece. The cylinder liners are of the
wet type and are replaceable. The liners have a
flame guard bevel which considerably increases the
service life of the cylinder head gaskets.

Crankshaft

The heavy-duty crankshaft is extremely strong and is
journalled in seven main bearings. This shaft is
statically and dynamically balanced and tempered
according to a special method (nitrocarburization).
This increases the fatigue strength and gives the
bearing journals an extremely hard surface.

Pistons

The pistons, which are made of an aluminum alloy,
have two compression rings and one oil ring. The
compression rings are coated (upper compression
ring in the TAMD63), which helps reduce oil con-
sumption and the risk of ring seizing.

To reduce carbonization at high engine loads the
pistons are oil cooled. Piston cooling increases the
service life of pistons, piston rings and cylinder liners
and reduces oil consumption.

The engine’s combustion chambers are entirely
confined to the piston crowns.
