Caterpillar 3412 Generator Set Engines are 27 liter (1649 cu. in.), 137 mm (5.4 in.) bore and 152.4 mm (6.0 in.) stroke, four cycle, 12 cylinder, 65 degree vee diesel design. The engine is available in twin turbocharged or series turbocharged arrangements with jacket water aftercooling and direct fuel injection.The engine and components are designed for high power output. The reduced size and weight plus increased fuel economy provide maximum performance and lower cost per unit of power. The 3412 Generator Set is offered at 1500 rpm, 50 Hz and 1800 rpm, 60 Hz arrangements with various output power ratings. Contact your Caterpillar dealer for information on these power ratings.Larger diameter plungers and a higher injection rate camshaft are incorporated in the valve train/fuel system. The fuel lines are made of high strength steel and the ends of the lines have collared washers to increase reliability. The cooling system has a gear driven centrifugal water pump, two thermostats (one for each bank) which regulate engine coolant temperature, and an oil cooler.The engine lubricating oil, which is both cooled and filtered, is supplied by a gear driven pump. Bypass valves provide unrestricted flow of lubrication oil to engine parts when oil viscosity is high, or either the oil cooler or oil filter elements should become plugged.The 3412 Generator Set Engine is electronically governed and features an exclusive electronic Engine Control Module (ECM). The ECM is a microprocessor-based system that provides full range isochronous speed governing which can operate in speed droop with a zero to ten percent adjustment range.The ECM also provides a cold mode starting strategy, air to fuel ratio control for transient smoke limiting, automatic turbocharger boost pressure and rack position sensor calibration, engine protection and diagnostics.The 3412 engines are equipped with the Electronic Modular Control Panel (EMCP II). The EMCP II is the next generation of engine/generator controls for more accurate, reliable monitoring of engine operating parameters and generator AC voltage metering.The SR4 generator features single bearing, wye connected, brushless, permanent magnet excited designed to match the output characteristics of the engine. These packaged generator sets are designed, manufactured and tested in accordance with ISO 9001 to ensure the highest possible quality on a worldwide basis.Engine efficiency and engine performance and efficiency of emissions controls depend on adherence to proper operation and maintenance recommendations, and the use of recommended fuels, coolants and lubrication oils. To minimize expenses and provide maximum utilization and performance of your
