For specifications, refer to the Specifications For 3176C & 3196 Marine Engines, RENR1231. If the Specifications in RENR1231 are not the same as in the Systems Operation, Testing & Adjusting, look at the printing date on the back cover of each book. Use the Specifications given in the book with the latest date.The engines are electronically controlled mechanically actuated unit injector diesel engines. The engine is an inline 6 cylinder arrangement with a bore of 130.0 mm (5.12 in) and a stroke of 150.0 mm (5.91 in) giving a total displacement of 11.95 L (747 cu in). The engine as configured is a low profile arrangement with the exhaust and inlet manifolds on the right hand side.The electronic unit injector system provides increased control of timing and fuel/air ratio control. Timing advance is achieved by precise control of injector timing. Engine rpm is controlled by adjusting the injection duration. A special pulse wheel provides information to the electronic control module for detection of cylinder position and engine rpm.The engine has built-in diagnostics to insure that all components are operating properly. In the event of a system component failure, the operator will be alerted to the condition via the dashboard mounted "check engine" light. A Caterpillar service tool can be used to read the numerical code of the faulty component or condition, or the flash code can be annunciated with a diagnostic lamp. Intermittent faults are "logged" and stored in memory.Starting The Engine
The ECM will automatically provide the correct amount of fuel to start the engine. Do not hold the throttle down while cranking the engine. At temperatures
