Volvo Penta TAD941GE Operator's Manual

VOLVO PENTA INDUSTRIAL DIESEL
TAD941GE
323 kW (439 bhp) at 1500 rpm, 344 kW (468 bhp) at 1800 rpm, acc. to ISO 3046
The TAD941GE is a powerful, reliable
and economical Generating Set Diesel
Engine built on the dependable Volvo in-
line six design.
Durability & low noise
Designed for the easiest, fastest and
most economical installation. Well bal-
anced to produce smooth and vibration-
free operation with low noise level, fea-
tured with high torque.
To maintain a controlled working tem-
perature in cylinders and combustion
chambers, the engine is equipped with
piston cooling. The engine is also fitted
with replaceable cylinder liners and valve
seats / guides to ensure maximum dura-
bility and service life of the engine.
Operational economy and
Low exhaust emission
The state of the art, high-tech injection
and air charging system with low internal
losses contributes to excellent combus-
tion and low fuel consumption.
The TAD941GE complies with EU
stage 2 and TA-luft exhaust emission
regulations.
Easy service & maintenance
Easily accessible service and mainte-
nance points contribute to the ease of
service of the engine.
Technical description
Engine and block
– Optimized cast iron cylinder block with opti-
mum distribution of forces without the block
being unnecessary heavy.
– Wet, replaceable cylinder liners
– Piston cooling for low thermal load on pis-
tons and reduced ring temperature
– Tapered connecting rods to reduce risk of
piston cracking
– Crankshaft induction hardened bearing
surfaces and fillets with seven main bear-
ings for moderate load on main and big-end
bearings
– Nitrocarburized transmission gears for heavy
duty operation
– Keystone top compression rings for long
service life
– Viscous type crankshaft vibration damper
– Replaceable valve guides and valve seats
– Over head camshaft and four valves per
cylinder equipped with camshaft damper to
reduce noise and vibrations.
Lubrication system
– Full flow oil cooler
– Full flow disposable spin-on oil filters, for
extra high filtration
– The lubricating oil level can be measured
during operation (Standard dipstick only)
– Gear type lubricating oil pump, gear driven
by the transmission
Fuel system
– Non-return fuel valve
– Electronic Unit Injectors
– Fuel pre-filter with water separator and
water-in-fuel indicator / alarm
– Gear driven low-pressure fuel pump
– Fuel pressure switch
– Self de-aerating system. When replacing
filters all fuel stays in the engine.
Turbo charger
– Efficient and reliable turbo charger
– Extra oil filter for the turbo charger
Cooling system
– Air to air intercooler
– Belt driven, maintenance-free coolant pump
with high degree of efficiency
– Fan hub
– Fan & belt guard
– Efficient cooling with accurate coolant con-
trol through a water distribution duct in the
cylinder block. Reliable sleeve thermostat
with minimum pressure drop
– Radiator
– Radiator guard
– Pusher type fan
Electrical system
– Engine Management System 2 (EMS 2), an
electronically controlled processing system
which optimizes engine performance. It also
includes advanced facilities for diagnostics
and fault tracing
– The instruments and controls connects to
the engine via the CAN SAE J1939 inter-
face and the Control Interface Unit (CIU).
The CIU converts the digital CAN bus signal
to an anolog signal, making it possible to
connect a variety of instruments.
– Sensors for oil pressure, oil temp, boost
pressure, boost temp, coolant temp, fuel
temp, water in fuel, fuel pressure and two
speed sensors. Crank case pressure, oil
level and air filter pressure droop sensors
– Alternator 24V / 80A
