VOLVO PENTA INDUSTRIAL DIESEL TAD942VE 250 kW (340 hp) crankshaft power acc. to ISO 3046 The TAD942VE is a powerful, reliable and economical Versatile Diesel Engine built on the dependable Volvo in-line six design. 7743936 - Downloaded from www.volvopenta.com 05/02/2013 13:15:39 Durability & low noise Designed for the easiest, fastest and most economical installation. Well balanced to produce smooth and vibrationfree operation with low noise level, featured with 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. 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 combustion and low fuel consumption. The TAD942VE complies with EU stage II exhaust emission regulations. Easy service & maintenance Easily accessible service and maintenance points contribute to the ease of service of the engine. Technical description Engine and block – Optimized cast iron cylinder block with optimum distribution of forces without the block being unnecessary heavy. – Wet, replaceable cylinder liners – Piston cooling for low thermal load on pistons and reduced ring temperature – Tapered connecting rods to reduce risk of piston cracking – Crankshaft induction hardened bearing surfaces and fillets with seven main bearings 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 control through a water distribution duct in the cylinder block. Reliable sleeve thermostat with minimum pressure drop – Tropical radiator – Radiator guard – Suction type fan, 750 mm or 890 mm 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 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. Crankcase pressure, piston cooling pressure, oil level and air filter pressure droop sensors – Alternator 24V / 80A
