Rethinking the way we fuel up

New technologies can make your aggregate operations more efficient, safer and even environmentally friendly, but they often come with a learning curve, requiring us to break old habits and rethink the way we do things. Tier 4 engine technology is one such new technology. Operators of Tier 4 engines have transitioned to quite different maintenance routines, including the way to properly handle fuel.

The Association of Equipment Manufacturers (AEM) has released a graphic to encourage equipment owners to “get CLEAN on fuel” to protect their Tier 4 engines. AEM says a committee of experts from member companies developed the graphic to help build awareness of the importance of diesel fuel quality. Some of the important takeaways from the graphic include:

• Buy your fuel from someone who maintains best practices throughout the storage and distribution process.
• Be aware that today’s diesel has an average shelf life of about six months.
• Ensure that your fuel handling systems are clean and use proper filtration.
• Refill fuel tanks at the end of a work shift to reduce condensation.

Today’s fuel is Ultra-Low Sulfur Diesel (ULSD) and it is very different from the diesel of just a few years ago. Among other things, it is subject to change and contamination as it moves from the refinery to the engine, making storage, temperature, age and filtration critical factors. AEM says, “Because fuel pressure in Tier 4 engines is as high as 45,000 psi, any contaminants can create erosion that negatively impacts engine performance, fuel economy and component life.”

Refueling safely
The removal of sulfur and other compounds in ULSD fuel decreases its conductivity and increases its ability to store static charge. Static electricity discharge when combustible vapors are present could result in a fire or explosion. Therefore, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, etc.) is properly bonded and grounded.

A properly bonded fuel delivery system has an electrically conductive and unbroken connection between all components. A properly grounded system has an electrically conductive connection from the fuel delivery system tank to earth ground to allow static and electrical charge dissipation.

Be sure your employees know how to fuel up safely.
