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 to ensure that all 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 on the dashboard. An electronic service tool can be used to read the numerical code of the faulty component or condition. 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 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 depends 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 enhancementsIt is not recommended to troubleshoot performance-related problems when the Cold Mode flag is active.The Cold Mode flag will activate when the coolant temperature is 35° C (95° F)Once coolant temperature is above 75° C (167° F), the cold mode strategy will not be active.Delayed Engine Shutdown (If Equipped)
The "Delayed Engine Shutdown" strategy allows the engine to run for a time after the engine start switch key is turned to the OFF position to cool the engine and system components. The engine start switch key may be removed.Note: There may be regulations that define the requirements for the operator and/or support personnel to be present when the engine is running.Note: The DEF purge process will run for 2 minutes once the engine is shut down and must
