The engine has a firing order of "1-5-3-6-2-4". The engine's 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 engines have a bore of 110 mm (4.3 inch) and a stroke of 127 mm (5.0 inch). The displacement is 7.25 L (442 cubic inch).These engines use the hydraulic electronic unit injector (HEUI) for fuel injection. The HEUI eliminates many of the mechanical components that are used in a pump-and-line system. The HEUI provides increased control of the timing and increased control of the fuel air mixture. The timing advance is achieved by precise control of the unit injector timing. Engine rpm is controlled by adjusting the injection duration. A special pulse wheel provides information to the Electronic Control Module (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 diagnostic lamp that is located on the control panel. An electronic service tool 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 hold the throttle open while the engine is cranking. If the engine fails to start in twenty 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).Under these conditions, low idle rpm will be increased to 1000 rpm. The engine's power will also be limited.Cold mode operation will be deactivated after any one of the following conditions:
The coolant temperature is above 18 °C (64 °F).
Fourteen minutes of runningAfter disabling, cold mode operation may ramp slowly back to 1000 rpm if the temperature conditions still exist.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.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.
