The 3176C 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 in3). The 3196 Engine has a bore of 130.0 mm (5.12 inch) and a stroke of 150.0 mm (5.91 inch). The displacement is 12 L (732 in3). Both engines have a firing order sequence:1, 5, 3, 6, 2 and 4. The rotation of these engines is counterclockwise when the engine is viewed from the flywheel end of the engine. These engines utilize a turbocharger and an air-to-air aftercooler.The 3176C and the 3196 Engines incorporate several major improvements. These components included a high pressure electronic unit injector system and an improved electronic control system. The new features enhance engine speed control and cold starting capabilities. The new features also 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. 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 by a check engine light. The check engine light is located on the dashboard. An electronic service tool can be used to read the numerical code of the faulty component or condition. 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.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 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 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 17 °C (63 °F).When the cold start strategy is activated, low idle rpm will be increased to 800 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 28 °C (82 °F).
The engine has been running for twelve 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 idle at the programmed low idle rpm in order to be put in gear.
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.Customer Specified Parameters
The engine is capable of being programmed for several customer specified parameters. For a brief explanation of each of the customer specified parameters, see the Operation and Maintenance Manual.
