Preventative Diagnostics: Oil Consumption as an Overhaul Indicator

Oil consumption, fuel consumption and maintenance information can be used to estimate the total operating cost for your generator's engine. Oil consumption can also be used to estimate the required capacity of a makeup oil tank that is suitable for the maintenance intervals.

Oil consumption is in proportion to the percentage of the rated engine load. As the percentage of the engine load is increased, the amount of oil that is consumed per hour also increases. The oil consumption rate (brake specific oil consumption) is measured in grams per kW/h (lb per bhp). Consult your USP&E technician for assistance in determining the typical oil consumption rate for your engine.

When a generator engine's oil consumption has risen to three times the original oil consumption rate due to normal wear, an engine overhaul should be scheduled. There may be a corresponding increase in vibration and a slight increase in fuel consumption.

USP&E performs daily preventative diagnostic testing to ensure your assets are being maintained at the highest possible standards.

Preventative Diagnostics: Severe Operation

One of the biggest advantages of outsourcing your power plant's maintenance to USP&E is our unceasing effort to maximize the life of your assets. One of the central ways your asset life is diminished is through unforeseen or undetected Severe Operation exposure. Severe operation is the use of an engine that exceeds current published standards for that engine. Severe operation can accelerate component wear. Engines that are operating under severe conditions may need more frequent maintenance intervals for the following reasons:

  • Maximum reliability
  • Retention of full service life

USP&E performs a thorough diagnostic evaluation to ensure that the proper maintenance strategies required for your specific engines are initiated. Some of the factors that contribute to severe operation are environment and improper maintenance practices. USP&E makes every effort to maximize asset life through avoiding all possible severe operation factors.

Preventative Diagnostics: Factors That Decrease Asset Life 

Extreme Ambient Temperatures

Extended operation in environments that are extremely cold or hot can damage components. Valve components can be damaged by carbon buildup if the engine is frequently started and stopped in very cold temperatures. Extremely hot inlet air reduces the performance capabilities of the engine.

Dust, Dirt and Airborne Chemicals

Unless equipment is cleaned regularly, extended operation in a dirty environment can damage your equipment. Built up mud, dirt and dust can encase components, making maintenance difficult. This buildup can contain corrosive chemicals and salt. Corrosive chemicals and salt can damage some components. USP&E believes strongly in maintaining the cleanest possible power plants in the industry.

Improper Maintenance Practices
  • Extension of maintenance intervals
  • Not using recommended fuel, lubricants and coolant/antifreeze

As a driving force behind your daily power plant maintenance regimen, USP&E will work to minimize these Severe Operation factors, maximizing fuel efficiency and optimizing asset life.
