Volvo Penta Enters New Market
Segment For Workboat Engines
With 16-Liter Marine Diesel
—Literature Offered— Volvo Penta's new TAMD162, 16-liter marine diesel is designed for lowest fuel consumption in the 1,400-1,600 rpm speed range.
Volvo Penta recently introduced
the new TAMD162, a* 16-liter ma-
rine diesel, which marks an upgrad-
ing of the company's marine engine
range and its entry into the market
segment for workboats with engines
of 400-600 hp.
The robust new engine has been
developed primarily for powering
fishing vessels and heavy-duty
workboats or as auxiliary engines in
large boats. It is available in three
standard power output classes: HD,
heavy duty (470 hp/345 kw at 1,800
rpm); MD, medium duty (490 hp/
360 kw); and LD, light duty (550 hp/
405 kw at 1,900 rpm). The engine is
designed for lowest fuel consump-
tion in the 1,400-1,600 rpm speed
range.
Important design advancements,
introduced in the new TAMD162,
16-liter, have also been incorporated
into the company's new 12-liter and
10-liter engines. Features include
new cylinder head and gaskets, new
cylinder liners with flame barriers
and improved sealing. The engine
has a new injection pump with
smoke limiter and new five-hole
nozzles for better combustion and
cleaner emissions.
In the 12-liter turbocharged and
aftercooled category, a new designa-
tion TAMD122 replaces the pre-
vious generation 121 engine. The
TAMD122 has between 4 and 7 per-
cent higher power output than its
predecessor. In the heavy-duty ver-
sion, the engine now rates at 380 hp/
279 kw, with 450 hp/331 kw for plea-
sure craft and light duty applica-
tions. The TAMD122 also features a
new lightweight gearbox.
In the 10-liter category, the tur-
bocharged 100 series of marine die-
sels has been replaced with a model
designated TMD102, also reflecting
an increase in power. Output in
medium-duty operation has been
increased by 5 percent to 272 hp/200
kw at 2,000 rpm.
The 16-liter TAMD162 is turbo-
charged, aftercooled and is fuel effi-
cient, quiet and light. Special char-
acteristics of the new engine include
high-power output in combination
with low fuel consumption, high re-
liability, long service life and low
levels of noise and exhaust emis-
sions.
Volvo Penta's first diesel engine
with four valves per cylinder for
engine efficiency, the six-cylinder
TAMD162 has a variety of other
special features designed to increase
