RIVET 6N2011 - Caterpillar

The engine can be turbocharged and jacket water aftercooled (TA), or turbocharged and air-to-air aftercooled (ATAAC) with direct fuel injection.A full range hydramechanical governor controls the fuel injection pump output to maintain the engine rpm selected by the operator.Individual injection pumps, one for each cylinder, meter and pump fuel under high pressure to an injection valve for each cylinder. Automatic timing advance provides the best fuel injection timing over the full range of engine speed.The cooling system consists of a gear driven centrifugal pump, with one thermostat which regulates the engine coolant temperature, an oil cooler and a radiator incorporating a shunt system.The engine lubricating oil, which is both cooled and filtered, is supplied by a gear-type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high, or if either the oil cooler or the oil filter elements should become plugged.Engine efficiency, efficiency of emission controls and engine performance depend on adherence to proper operation and maintenance recommendations, and the use of recommended fuels and lubrication oils.Follow the recommended Maintenance Management Schedule with emphasis on emission related components, air cleaner, oil, oil filter, fuel and fuel filter maintenance found in this publication.Engine Identification
Caterpillar engines are identified with serial numbers, OT (fuel system settings) numbers and arrangement numbers. In some cases modification numbers are also used. These numbers are shown on the serial number plate mounted on the engine.Caterpillar dealers need all of these numbers to determine which components were included on the engine when it was assembled at the factory. This permits accurate identification of replacement part numbers.
