VOLVO PENTA INDUSTRIAL DIESEL The TAD731GE is a powerful, reliable and economical Generating Set Diesel Engine built on the dependable in-line six design. 7748766 - Downloaded from www.volvopenta.com 29/08/2013 08:35:27 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 temperature 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 durability and service life of the engine. The state of the art, high-tech injection and charging system with low internal losses contributes to excellent combustion and low fuel consumption. The TAD731GE complies with EU Stage 2 and TA-Luft exhaust emission regulations. Easy service & maintenance Easily accessible service and maintenance points contribute to the ease of service of the engine.
