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. A 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. Operating the engine at a load level that is greater than 30% will also maintain engine efficiency and performance. This action will burn excess carbon from the cylinders.
