(8) Exhaust manifold The Mechanical Electronic Unit Injector (MEUI) fuel system is used on this engine. The MEUI fuel system eliminates many of the mechanical components that are used in a pump and lines. The electronic control and mechanical actuation provides increased control of the timing and increased control of the fuel injection pressure. The timing advance is achieved by precise control of the unit injector timing. Engine speed is controlled by adjusting the injection duration. A special speed-timing wheel provides information to the Electronic Control Module (ECM) for detection of cylinder position and engine speed.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. Caterpillar Electronic Technician (ET) can be used to read the numerical code of the faulty component or condition. Intermittent faults are also logged and stored in memory.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 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 20 °C (68 °F).When the cold start strategy is activated, low idle rpm will be increased and engine power will be limited.Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 20 °C (68 °F).
The engine has been running for 12 minutes.Cold mode operation uses a modified control map, that is stored in the ECM, in order to adjust the fuel injection timing and the injection duration for white smoke cleanup. The engine will usually exit the cold mode operation before the walk-around inspection is completed. During cold mode operation, the engine will remain at the elevated rpm that has been specified for the engine.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.Customer Specified Parameters
The engine can be programmed for several customer specified parameters. For a brief explanation of each of the customer specified parameters, refer to the Operation and Maintenance Manual
