Aeromotive Relies on Cat Fuel Filters

Aeromotive is the world’s leading manufacturer of high-performance fuel pumps.  The company was a runner up for Best  New Engineered Product at the recent Specialty Equipment Manufacturers Association (SEMA) show in Las Vegas.  The diesel fuel pump utilizes a Cat filter, testament to the quality of filtration found in all Cat filters.

This level of filtration is equally important in today’s Tier IV engines because more advanced engines demand cleaner systems.

When you talk to end users about their filter choices, it’s not uncommon to hear "I’ve used Brand X filters for years and never had any issues."  This is not surprising and, in fact, fuel systems in older equipment were more tolerant of contamination.

But as demands for lower emissions, improved performance and reduced fuel consumption have intensified, fuel injection system designs have changed.  The most prominent design trend is a steady increase in maximum injection pressure in newer diesel engines.  Ten years ago injection pressures were in the sub-10,000 PSI range, today they are exceeding 30,000 PSI.

How do increased injection pressures ultimately affect you and your equipment from a filtration perspective? Tier 4 fuel systems are highly sensitive to contamination and, as such, require superior filtration.  As injector pressures increase, maximum injector life is accomplished by limiting the size and number of particles that get through the fuel filter.  All fuel filters remove some abrasive particles, but many competitive filters are simply not effective at capturing and retaining the particles that are most damaging to fuel system components.  We’re not talking about boulder-sized particles.  Today’s fuel systems require filtration capable of removing particles in the sub-four micron range.  (A human hair is 100 microns in diameter!)

Under fuel these high fuel system pressures, poorly filtered fuel can cause some serious damage.  Think of it this way.  Imagine you have a hand full of sand and you throw it against a painted surface, say a car door.  Not much happens, maybe some minute scratches, but nothing especially noticeable.  Now, take that same handful of sand and apply added pressure from an air compressor.  It will quickly and effortlessly remove the paint from that car door.  In some scenarios it can actually create holes in the metal surface.  This scenario is what takes place inside a fuel system when contaminants interact with the internal components at high pressure.  They quickly erode away at various mating surfaces that ultimately have a negative impact on equipment performance and fuel economy.
