Locomotive Fuel Filtration Application Explained

Improved Reliability Through Cleaner Fuel: 

The Power Drives (PDI) /Schroeder Fuel Filtration Solution

The driving force in Diesel Fuel Filtration are the requirements that Tier 3 and 4 engines will need to meet to lower particulate entrainment levels, as well as reduced tolerance for entrained water. Non Tier 4 locomotives will also benefit by removing particulates that cause wear and tear and malfunctions of critical components, enhancing the life of the locomotive.

Three Key Characteristics of any Filter 

• Dirt Holding Capacity:  Amount of debris the elements can hold.  This dictates service life of the elements between change-outs.
• Efficiency:  How effective is the element at removing particulate (ISO Code 4406 looks at three specific particle size ranges < 4 micron, < 6 micron and < 14 micron)
• Pressure Drop:  Amount of resistance in PSI the fuel must overcome to travel through the element.  Lower pressure drops equal improved fuel flow
