The engine has two turbochargers. The engine arranges the two turbochargers in series. The two turbochargers allow the engine to have boost over the entire engine rpm range. The use of two turbochargers increases the maximum boost pressure to
The Electronic Unit Injector (EUI) provides increased control of the timing and increased control of the fuel air mixture. Engine rpm is controlled by adjusting the injection duration. Engine timing is controlled by the precise control of fuel injection timing.
The Engine Control Module (ECM) monitors the components of the engine during operation. In the event of a component failure, the operator will be alerted to the condition by the use of a amber warning lamp and an event code will be logged in the ECM. Caterpillar Electronic Technician (ET) can be connected to the engine in order to read any logged faults. Also, the cruise control switches can be used to flash the code on the check engine light. Intermittent faults are logged and stored in memory.
The engine's 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 30 seconds, release the starting switch. Allow the starting motor to cool for two minutes before the starting motor is used again.
