The TAD734GE is a powerful, reliable
and economical Generating Set Diesel
Engine built on the dependable in-line six
design.
Durability & low noise
Designed for easiest, fastest and most
economical installation. Well-balanced to
produce smooth and vibration-free opera-
tion with low noise level.
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 durabil-
ity and service life of the engine.
Low exhaust emission
The state of the art, high-tech injection
and charging system with low internal
losses contributes to excellent combus-
tion and low fuel consumption.
The TAD734GE complies with EU Stage
2 exhaust emission regulations.
Easy service & maintenance
Easily accessible service and mainte-
nance points contribute to the ease of
service of the engine.

Cooling system
– Belt driven, maintenance-free coolant pump
with high degree of efficiency
– Efficient cooling with accurate coolant con-
trol through a water distribution duct in the
cylinder block
– Reliable thermostat with minimum pressure
drop
– Pusher 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 connect to the
engine via the CAN SAE J1939 interface,
either through the Control Interface Unit
(CIU) or the Display Control Unit (DCU).
The CIU converts the digital CAN bus signal
to an anolog signal, making it possible to
connect a variety of instruments. The DCU is
a control panel with display, engine control,
monitoring, alarm, parameter setting and di-
agnostic functions. The DCU also presents
error codes in clear text.
– Sensors for oil pressure, boost pressure,
boost temp, exhaust temp, coolant temp,
water in fuel, fuel pressure and two speed
sensors.
Features
– Electronic governing, EMS2
– CAN bus communication
– Compact design for the power class
– High power to weight ratio
– Emission compliant
– Noise optimized engine design
– Dual speed
