VOLVO PENTA INDUSTRIAL DIESEL TAD1344VE 352 kW (479 hp) at 2100 rpm acc. to ISO 3046 The TAD1344VE is a powerful, reliable and economical Versatile Diesel Engine built on the dependable Volvo in-line six concept. 7749499 - Downloaded from www.volvopenta.com 05/02/2013 13:32:24 Durability & low noise Designed for easy, fast and economical installation. Field tested to ensure highest standard of durability and long life. Well-balanced to produce smooth and vibration-free operation with low noise levels and high torque. 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. Low exhaust & noise emission The state of the art, high-tech injection and highly efficient charge air system with low internal losses contributes to excellent combustion and low fuel consumption. The TAD1344 VE complies with EU Stage 2 / EPA Tier 2 emissions. An electronically controlled viscous fan drive is available giving substantially lower noise and fuel consumption. Features – – – – – – Easy service & maintenance Easily accessible service and maintenance points contribute to the ease of service of the engine. Technical description Engine and block – Cast iron cylinder block with optimum distribution of forces without the block being unnessarily heavy. – Wet, replaceable cylinder liners – Piston cooling for low piston temperature and reduced ring temperature – Tapered connecting rods for increased piston lifetime – Crankshaft induction hardened bearing surfaces and fillets with seven bearings for moderate load on main and high-end bearings – Case hardened and Nitrocarburized transmission gears for heavy duty operation – Keystone top compression rings for long service life – Viscous type crankshaft vibration dampers – Replaceable valve guides and valve seats – Over head camshaft and four valves per cylinder High torque Highly efficient cooling system with Air to Air Intercooler High power density Fully electronic with EMS 2 Complies with EU Stage 2 / EPA Tier 2 emissions Wide range of optional equipment including visco fan. Lubrication system – Full flow oil cooler – Full flow disposable spin-on oil filter, for extra high filtration – The lubricating oil level can be measured during operation – Gear type lubricating oil pump, gear driven by the transmission – Oil level sensor at startup Fuel system – Electronic high pressure unit injectors – Fuel prefilter with water separator and waterin-fuel indicator / alarm – Gear driven low-pressure fuel pump – Fine fuel filter with manual feed pump and fuel pressure switch Cooling system – Efficient cooling with accurate coolant control through a water distribution duct in the cylinder block. Reliable sleeve thermostat with minimum pressure drop – Belt driven coolant pump with high degree of efficiency – Electronically controlled viscous fan drive provides lower noise and fuel consumption (optional). Turbo charger – Efficient and reliable turbo charger – Electronically controlled Waste-gate – Extra oil filter for the turbo charger 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. – Possibility to perform a start battery test according to the NCPA requirements via CAN bus signals. – The instruments and controls connect to the engine via the CAN SAE J1939 interface, either through the Control Interface Unit (CIU) or the Digital 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 diagnostic functions. The DCU also presents error codes in clear text. – Sensors for oil pressure, oil temp, boost pressure, boost temp, coolant temp, fuel temp, water in fuel, fuel pressure and two speed sensors.
