The C-10 Engine has a bore of 125.0 mm (4.92 inch) and a stroke of 140.0 mm (5.51 inch). The displacement is 10.3 L (629 cu in). The engine has the following firing order sequence: 1, 5, 3, 6, 2, 4. The engine rotation is counterclockwise when the engine is viewed from the flywheel end. The engine utilizes a turbocharger.The C-10 Engine incorporates several major improvements. These components include an improved electronic control system. The new features lower the smoke level for emissions under all operating conditions.The Electronic Unit Injector system eliminates many of the mechanical components that are traditionally used in the fuel injector assembly. The Electronic Unit Injector (EUI) also provides increased control of the timing and the fuel air mixture. The timing advance is achieved by precise control of the fuel injection timing. Engine rpm is controlled by adjusting the injection duration. 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 by a warning lamp or a diagnostic lamp. Caterpillar Electronic Technician (ET) can be used to read the numerical code of the faulty component or condition. Intermittent faults are logged and stored in memory.Starting The Engine
The engine's ECM will automatically provide the correct amount of fuel in order to start the engine. Do not advance the throttle downward while the engine is cranking. If the engine fails to start in 30 seconds, release the starting switch. Allow the starting motor to cool for two minutes before using the starting motor again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
The ECM will set the cold start strategy when the coolant temperature is below 18 °C (64 °F).When the cold start strategy is activated, low idle rpm will be increased to 1000 rpm and the engine's power will be limited.Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 18 °C (64 °F).
The engine has been running for fourteen minutes.Cold mode operation varies the fuel injection amount for white smoke cleanup. Cold mode operation also varies the timing for white smoke cleanup. The engine operating temperature is usually reached before the walk-around inspection is completed. The engine will then idle at the programmed low idle rpm.
A machine equipped with this electronically controlled engine should not be moved until it is out of Cold Mode operation.If the machine is operated while in Cold Mode operation power will be noticeably reduced.
After the cold mode is completed, the engine should be operated at low rpm until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low rpm and low power demand.Programmable Parameters
The engine is capable of being programmed for several parameters. For a brief explanation of each of the programmable parameters, see the Operation and Maintenance Manual.
