VOLVO PENTA INDUSTRIAL DIESEL
TAD731GE
148 kW (201 hp) at 1500 rpm, 154 kW (210 hp) at 1800 rpm
The TAD731GE 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
operation 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 dura-
bility 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 TAD731GE complies with EU Stage
2 and TA-Luft exhaust emission regula-
tions.
