The TAD1242GE is a powerful, reliable and economical Generating Set Diesel Engine built on the dependable in-line six design.

Durability & low noiseDesigned 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 emissionThe state of the art, high-tech injection and charging system with low internal losses contributes to excellent combus-tion and low fuel consumption. The TAD1242GE complies with EU Stage 2 and TA-Luft -50% exhaust emis-sion regulations.

Easy service & maintenanceEasily accessible service and mainte-nance 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 unnessarily heavy.

Wet, replaceable cylinder liners Piston cooling for low piston temperature

and reduced ring temperature Tapered connecting rods for reduce risk of

piston cracking Crankshaft induction hardened bearing

surfaces and fillets with seven bearings for moderate load on main and high-end bear-ings

Case hardened and Nitrocarburized trans-mission gears for heavy duty operation

Keystone top compression rings for long service life

Viscous type crankshaft vibration dampers to withstand single bearing alternator tor-sional vibrations

Replaceable valve guides and valve seats Over head camshaft and four valves per cyl-

inder

Lubrication system Full flow oil cooler Full flow disposable spin-on oil filter, for ex-

tra high filtration The lubricating oil level can be measured

during operation Gear type lubricating oil pump, gear driven

by the transmission

Fuel system Non-return fuel valve Electronic Unit Injectors Fuel prefilter with water separator and wa-

ter-in-fuel indicator / alarm Gear driven low-pressure fuel pump Fine fuel filter with manual feed pump and

fuel pressure switch Fuel shut-off valve, electrically operated

Cooling system Efficient cooling with accurate coolant con-

trol through a water distribution duct in the cylinder block. Reliable sleeve thermostat with minimum pressure drop

Gear driven, maintenance-free coolant pump with high degree of efficiency

Coolant filter as standard

Turbo charger Efficient and reliable turbo charger Extra oil filter for the turbo charger

Electrical system Electronical Diesel Control III (EDCIII), an

electronically controlled processing system which optimizes engine performance. It also includes advanced facilities for diagnostics and fault tracing

Three different ways for the customer to connect his controls and instrument to the engine. CAN SAE J1939 interface, CIU (Control interface unit) and Stand alone connections.

Sensors for oil pressure, oil temp, boost pressure, boost temp, coolant temp, fuel temp, water in fuel, fuel pressure and two speed sensors.

Features Maintained performance, air temp 40C Tropical cooling system (55C) Fully electronic with Volvo Penta EDC III Dual frequency switch (between 1500 rpm and 1800 rpm) High power density Emission compliant Low noise levels Gen Pac configuration

Power StandardsThe engine performance corresponds to ISO 3046, BS 5514 and DIN 6271. The technical data applies to an engine without cooling fan and operating on a fuel with calorific value of 42.7 MJ /kg (18360 BTU/lb) and a density of 0.84 kg/liter (7.01 lb/US gal), also where this involves a deviation from the standards. Power output guaranteed within 0 to +2% att rated ambient conditions at delivery. Ratings are based on ISO 8528. Engine speed governing in accordance with ISO 3046/IV, class A1 and ISO 8528-5 class G3Exhaust emissionsThe engine complies with EU stage 2 emission legislation according to the Non Road Directive EU 97/68/EEC. The engine also complies with TA-luft -50% exhaust emission regulations.

Rating GuidelinesPRIME POWER rating corresponds to ISO Standard Power for continuous operation. It is applicable for supplying electrical power at variable load for an unlimited number of hours instead of com-mercially purchased power. A10 % overload capability for govering purpose is available for this rating. MAXIMUM STANDBY POWER rating corresponds to ISO Standard Fuel Stop Power. It is applicable for supplying standby electrical power at variable load in areas with well established electrical networks in the event of normal utility power failure. No overload capability is available for this rating.1 hp = 1 kW x 1.36InformationFor more technical data and information, please look in the Gener-ating Set Engines Sales Guide.
