Cylinders and Arrangement In-line six-cylinder

Stroke 157 mm (6.2 inch)
Displacement 12.5 L (763 in3)
Firing Order 1-5-3-6-2-4
Rotation (flywheel end) Counterclockwise The electronic engines that are covered by this manual have the following characteristics: direct fuel injection, electronic unit injection that is mechanically actuated, turbocharged and air-to-air aftercooled (ATAAC).The electronic engine control system provides the following functions: electronic governing, automatic air to fuel ratio control, torque rise shaping, injection timing control and system diagnostics.An electronic governor controls the output of the unit injectors in order to maintain the engine rpm that is desired. The functions of the governor include a programmable low idle and a 20 rpm to 200 rpm governor overrun.Very high injection pressures are produced by electronically controlled, mechanically actuated unit injectors. The injectors combine the pumping and the electronic fuel metering (duration and timing) during injection. The unit injectors accurately control smoke limiting, white smoke, and engine acceleration rates.There is one unit injector per cylinder. Individual unit injectors meter the fuel. The individual unit injectors also pump the fuel. The metering and the pumping is done under high pressure. High injection pressures help to reduce fuel consumption and emissions. The use of this type of unit injector provides total electronic control of injection timing. The injection timing varies with engine operating conditions. The engine performance is optimized in the following areas:
Starting
Emissions
Noise
Fuel consumptionThe timing advance is achieved through precise control of the injector firing. Engine speed is controlled by adjusting the firing duration. The information is provided to the Electronic Control Module (ECM) by an engine speed/timing sensor. The information is for detection of cylinder position and engine speed.The engines have built-in diagnostics in order to ensure that all of the components are functioning and operating properly. If a system component deviates from the programmed limits, the operator is alerted to the condition by a DIAGNOSTIC lamp mounted on the control panel. An electronic service tool that is provided by Cat may be used to read the numerical code of the diagnostic flash code. There are three types of diagnostic codes: ACTIVE, LOGGED and EVENT. These codes are logged and stored in the ECM. Refer to the Operation and Maintenance Manual, "Engine Diagnostics" for additional information.The cooling system consists of the following items: a centrifugal pump that is driven by a gear, water temperature regulator, an oil cooler and a radiator that incorporates a shunt system.The engine lubricating oil is supplied by a gear type pump. The engine lubricating oil is cooled and filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine when the oil viscosity is high and when the oil cooler or the oil filter elements (paper cartridge) become plugged.Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations
