The engine rotation is counterclockwise when the engine is viewed from the flywheel end of the engine. The engine utilizes a turbocharger and an air-to-air aftercooler. The engine has a bore of 115.0 mm (4.53 inch) and a stroke of 149.0 mm (5.87 inch). The displacement is 9.3 L (568 cu in ).The fuel system eliminates many of the mechanical components that are used in a pump-and-line system. The fuel system also provides increased control of the timing and increased control of the fuel air mixture. The timing advance is achieved by precise control of the fuel injector timing. Engine rpm is controlled by adjusting the injection duration. A special pulse wheel provides information to the ECM for detection of cylinder position and engine rpm.The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition via the check engine light located on the dashboard. An electronic service tool can be used to read the numerical code of the faulty component or condition. Also, viewing the flash code through the operator display or the interface may be possible. Viewing the flash code is dependent on the engine application. Refer to the Operation and Maintenance Manual for further information on viewing fault codes through the operator display or interface.Starting The Engine
The engine ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in 20 seconds, release the starting switch. Allow the starting motor to cool for 2 minutes before the starting motor is used again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
Starting the engine and operation in cold weather is dependent on the type of fuel used, the oil viscosity, and other optional starting aids. For more information, refer to the Operation and Maintenance Manual, "Cold Weather Operation".The Cold Mode flag in Caterpillar Electronic Technician (ET) indicates that the engine system is compensating with a cold mode strategy.Some examples of a cold mode strategy may include:
Elevated RPM
Timing enhancements
Fuel injection enhancementsTroubleshooting performance-related problems when the Cold Mode flag is active is not recommended.The Cold Mode flag will activate in the following conditions:
Coolant temperature is less than 35° C (95° F)
Coolant temperature is less than 75° C (167° F) and NRS
