The engines are four-stroke, 6 cylinder in-line marine
diesel engines with direct injection. They are
equipped with turbochargers, charge air coolers
(CACs) and heat exchangers for thermostat-control-
led freshwater cooling.
The charge air cooler (CAC), which is seawater-
cooled, lowers the temperature of the inlet air to the
engine after compression in the turbocharger. This
permits a high power output while keeping the com-
bustion and exhaust gas temperatures to appropriate
levels.
TAMD71B: To reduce exhaust emissions when oper-
ating at low load, e.g. after (cold-) starting, there is a
by-pass valve which closes the air passage through
the charge air cooler (CAC) and instead channels the
air directly into the engine’s inlet manifold via the
electrical preheating element.
Introduction
This equipment is not necessary in the TAMD63,
TAMD73 and TAMD74 as they have a different spec-
ification, for example, higher compression, a different
combustion chamber, and a modified injection sys-
tem.
The TAMD73P (“TAMD73EDC”) and TAMD74C/L/P
(“TAMD74EDC”) are equipped with an electronically
controlled governor, Electronic Diesel Control
(“EDC”).* This further reduces exhaust emissions.
The exhaust manifold and turbocharger are fresh-
water-cooled to reduce the radiant heat to the engine
compartment.
For a more detailed description of the engine, its fuel,
lubrication, and cooling systems, etc., see “Techni-
cal descriptions” on pages 43–70.
*Note. EDC = “Electronic Diesel Control”.
