IMPELLER-PUMP 7E3174 - Caterpillar

The Caterpillar 3406C Generator Sets consist of an engine, a generator and control systems.Intended Use
This Power Generator is intended to be used to generate electrical power.Engine Information
The 3406C Generator Set Engine is an in-line six cylinder engine with direct fuel injection.A hydramechanical governor controls the fuel injection pump output. The output maintains the desired engine speed. An automatic timing advance provides the best fuel injection timing over the full range of engine speeds.Inlet air is filtered by an air cleaner. The air is compressed by a turbocharger before the air enters the engine cylinders. The turbocharger is driven by engine exhaust. The standard engine is turbocharged with jacket water aftercooling.The engine is a four cycle engine. Each cylinder head has two inlet valves and two exhaust valves. The rocker arms and the valves are actuated by the camshaft. The action is performed by mechanical lifters and pushrods.Engine Cooling and Lubrication
The cooling system consists of the following components:
A centrifugal pump that is driven by gears
A thermostat which regulates the engine coolant temperature
An oil cooler
A radiator or expansion tank (incorporating a shunt system)The engine lubricating oil, that is supplied by a gear type pump, is cooled. The engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)Engine efficiency, efficiency of emission controls and engine performance depend on adherence to proper operation and maintenance recommendations. Engine performance and efficiency also depend on the following items:
Use of recommended coolant/antifreeze
Use of recommended fuels
Use of recommended lubrication oilsRefer to the recommended Maintenance Interval Schedule in this publication in order to maintain the following emission related components:
Air cleaner
Engine oil
Oil filter
Fuel
Fuel filterGenerator Description
These brushless generators are used with the following loads: mixed loads of motors and lights, SCR-controlled equipment, computer centers, installations of communications and petroleum drilling applications. The elimination of the brushes in the field circuit reduces maintenance. The elimination of the brushes in the field circuit increases reliability. The elimination of brushes provides a higher degree of protection in potentially hazardous atmospheres.The generator set packages can be utilized for prime power generation or standby power generation. The generator set packages can be used in land based applications or marine applications.The generators have four poles. The generators have six or twelve lead configurations. The configuration depends on the frame size. The generators are capable of producing electrical power in either 50 Hz or 60 Hz applications.Specifications
