3512B Marine Auxiliary Engine Caterpillar

The efficiency of the engine can affect the fuel economy. Caterpillar's design and technology in manufacturing provides maximum fuel efficiency in all applications. Follow the recommended procedures in order to attain optimum performance for the life of the engine.

• Avoid spilling fuel.

Fuel expands when the fuel is warmed up. The fuel may overflow from the fuel tank. Inspect fuel lines for leaks. Repair the fuel lines, as needed.

• Be aware of the properties of the different fuels. Use only the recommended fuels.

• Avoid unnecessary idling.

Shut off the engine rather than idle for long periods of time.

• Keep the screens for the inlet air clean.

• Ensure that the turbochargers are operating correctly so that the proper air/fuel ratio is maintained. Clean exhaust indicates proper functioning.

• Maintain a good electrical system.

• Ensure that all of the connections of the hoses are secure.

• Ensure that the driven equipment is in good working order.

• Cold engines consume excess fuel. Utilize heat from the jacket water system and the exhaust system, when possible. Keep cooling system components clean and keep cooling system components in good repair. Never operate the engine without water temperature regulators. All of these items will help maintain operating temperatures.
