The Caterpillar 3054E and the 3056E Industrial Engines are designed with electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine and auxiliary monitoring
Engine speed governing
Cold start strategy
Automatic air/fuel ratio control
Integrated ether start
Torque rise shaping
Automatic altitude compensation
Fuel temperature compensation
Injection timing control
System diagnosticsFor more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Diagnostics
The engine has built-in diagnostics in order to ensure that all of the components are functioning properly. In the event of a deviation from the programmed limits, the operator will be alerted to the condition by a "DIAGNOSTIC" lamp that is mounted on the dashboard. Under certain conditions, the engine horsepower and the vehicle speed may be limited. A Caterpillar Electronic Technician (Cat ET) may be used to display the diagnostic codes.There are three types of diagnostic codes: active, logged and event.Most of the diagnostic codes are logged and stored in the ECM. For additional information, refer to the Operation and Maintenance Manual, "Engine Diagnostics" topic (Operation Section).The ECM provides an electronic governor that controls the injector output in order to maintain the desired engine rpm. The functionality of electronic governor is similar to the Caterpillar mechanical governor, but the electronic governor includes additional features.Engine Cooling and Lubrication
The cooling system consists of the following components:
Gear-driven centrifugal water pump
Water temperature regulators which regulate the engine coolant temperature
Gear-driven oil pump (gear type)
Oil coolerThe engine lubricating oil is supplied by a gear type pump. The engine lubricating oil is cooled and the engine lubricating oil is filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high. Bypass valves can also provide unrestricted flow of lubrication oil to the engine parts if the oil cooler should become plugged or if the oil
