When talking to decline users more or less their filter choices, we often hear, I have used XXX brand filter for years and never had any issues. And, if wein symbol to talking very more or less older fuel systems, its actually not a surprising recognition, because those systems were inherently more obliging of contamination. As demands for degrade emissions, bigger be in, and shortened fuel consumption have intensified, fuel injection system designs have distorted.
Heavy Equipment Filtration Choices
The most prominent design trend is a steady enhancement in maximum injection pressure in newer diesel engines. (Jskelinen, 2015). Where just 10 years ago injection pressures were in the sub 10,000 PSI (70 MPa) range; today they are more than 30,000 PSI (200 MPa).
Tier 4 Fuel Systems Require Great Filtration
So the ask is, how attain increased injection pressures ultimately play-court battle you and your equipment from a filtration viewpoint of view? The immediate agreementTier 4 fuel systems are highly goal to contamination and so require difficult filtration. As injector pressures amassed, maximum injector simulation is competent by limiting the size and number of particles that profit through the fuel filter. All fuel filters cut off some abrasive particles but many competitive filters are for that defense not supple at capturing and retaining the particles that are most damaging to fuel system components. In engineer-speak, fuel systems require filtration gifted of removing particles in the sub-four micron range.
To put this into position, imagine your hand full of sand. You be of the same mind to that sand and throw it neighboring-door-door to a painted surface, make known a car right of access. Not much happens right? Perhaps some minute scratches, but nothing overly noticeable. Now if you pronounce you will that united handful of sand and apply extra pressure from an environment compressor, it will speedily and effortlessly cut off the paint from that car right to use. In some scenarios it can actually make holes in the metal surface. This scenario is what takes place inside a fuel system as soon as contaminates interact as soon as the internal components at high pressure. They speedily erode away at various mating surfaces that ultimately have a negative impact concerning equipment perform and fuel economy.
Caterpillar Puts Hi-tech Efficiency Fuel Filters To The Test
Caterpillar has completed psychoanalysis upon injector cartoon in a Cat C9 engine fuel system. The test rig consisted of a factory cylinder head, fuel injectors, fuel pump, lines, and electronics. Highly distorted fuel was circulated through the system at rated and high idle to simulate an totally barbed vigorous feel. The test was terminated if the injector exhibited a leakage rate 3X that of accumulation or achieved 50 hours in duration. The Cat 1R-0749 Advanced High Efficiency Fuel Filter was pitted adjacent four same competitive filter brands to compare injector cartoon. Two filters for each brand were tested and the results averaged together to function the exploit for each brand. The injectors once Cat filtration lasted 45% longer than the nearest competitor.
How Can Inadequate Filtration Affect Your Back Line ?
Its challenging to determine the definite cost of inadequate filtration because rarely can you attraction a lecture to cause and effect lineage from a catastrophic failure to your option of filters. However, if you monitor in calm hour failures across components in the system you can begin to calculate a bottom pedigree cost. As portion of Caterpillars injector psychotherapy, we monitored to the lead-hour failures across the energy of the injectors as soon as using swap brands of filters.
When comparing the five peak brands of fuel filters, you could do a cost savings at the filter get ranging from 33 to 44% (upon a $20 filter, thats in this area $6.60 - $8.80 USD). And even though you may begin out ahead by a few dollars, the exam data simply shows you will unexpectedly experience the effects of premature, forward-hour injector failures. This could ensue less taking place costing you thousands of dollars. Why take on board to the risk?
How Do You Know If You Have a Fuel Filtration Damage ?
To admission this investigate, we have to examine other one what realize you drive by filtration agonized? A common illness we hear from users is that Cat Filters clog occurring too fast! So they switch to another brand of filter and the filter no longer clogs. Lets think approximately that: If the Cat filter is plugging and the non-Cat filter is not, what does that make known you? It tells you the hardship is that the non-Cat filter is NOT capturing and holding contaminates and allowing them to appendix freely through the fuel system. That is a concrete fuel filtration problem.
So, how realize you know later a filter is clogged? Most newer machines will manage to pay for a malformation code that basically is an indicator that differential pressure (Delta P) has increased to the narrowing that the bypass valve is flexibility. Once this occurs the filter should be changed out suddenly. If you dont, the robot will eventually de-rate to a low gift pay for leave to enter leading to decreased productivity and eventual downtime.
The trend for higher injection pressures is likely to continue. Youll acquire the maximum recompense in play in and fuel system wear simulation by investing a few auxiliary dollars in environment filters.
