38 SEBU7901-01 Operation Section Engine Operation Engine Operation i01196062 Engaging the Driven Equipment i02176671 Engine Operation SMCS Code: 1000 SMCS Code: 1000 If the load varies, or if the load is cyclic, the governor will adjust the engine rpm, as needed. Correct operation and maintenance are key factors in obtaining the maximum life and economy of the engine. If the directions in the Operation and Maintenance Manual are followed, costs can be minimized and engine service life can be maximized. Extended operation at low idle or extended operation at a reduced load may cause increased oil consumption and carbon buildup in the cylinders.
This carbon buildup results in a loss of power and/or poor performance. When the engine is operated at a reduced load, the engine should be fully loaded at every four hours in order to burn excess carbon from the cylinders. The engine can be operated at the rated rpm after the engine reaches operating temperature. The engine will reach normal operating temperature sooner during a low engine speed (rpm) and during a low power demand. This procedure is more effective than idling the engine at no load. The engine should reach operating temperature in a few minutes. Industrial Engines Gauge readings should be observed and the data should be recorded frequently while the engine is operating.
Comparing the data over time will help to determine normal readings for each gauge. Comparing data over time will also help detect abnormal operating developments. Significant changes in the readings should be investigated. 1. When the engine is operating, check the engine gauges. The engine gauges should be in the normal range before you engage the driven equipment. 2. Engage the driven equipment. Begin operating the engine at low load. Check the gauges and check the equipment for proper operation. Check the gauges and check the equipment frequently while the engine is operating under load. i00808595 Engine Warm-up i01878039 Fuel Conservation Practices SMCS Code: 1000 1.
Run the engine at low idle for three to five minutes, or run the engine at low idle until the jacket water temperature starts to rise. SMCS Code: 1000; 1250 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. More time may be necessary when the temperature is below н 18° C (0° F). 2. Check all of the gauges during the warm-up period. Avoid spilling fuel. 3. Perform another walk-around inspection. Check the engine for fluid leaks and air leaks.
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. 4. Increase the rpm to the rated rpm. Check for fluid leaks and air leaks. The engine may be operated at full rated rpm and at full load when the engine oil temperature reaches 60° C (140° F). Be aware of the properties of the different fuels. Use only the recommended fuels. Avoid unnecessary operation at no load. Shut off the engine instead of operating the engine at no load for long periods of time.
