Operating the Engine and the Driven Equipment
Check the gauges and the driven equipment frequently while the engine is operating under a load. The engine can be operated for extended periods of time at full load.Partial Load Operation
Extended operation at reduced load (less than 30%) may cause increased oil consumption and carbon buildup in the cylinders. Extended operation at reduced load may also cause fuel to slobber through the exhaust system. Loss of power and/or poor performance may result.To maintain engine efficiency and performance, apply a full load to the engine on an hourly basis. The engine can also be operated at a load level that is greater than 30 percent. These conditions will burn excess carbon from the cylinders.When possible, before shutting down the engine after running the engine for extended periods at low load, apply a full load for approximately 30 minutes. Running the engine at full load allows excess carbon to burn from the following components: cylinders, pistons and valves. Partial Load Operation In Cold Weather
Operation of the jacket water heater is recommended if the engine is operating at a low load in extreme cold.
