Magnetic Oil Filters
The
importance of oil filtration systems and equipment has increased vastly over
the years. To aid the conventional oil filter systems, engine oil additive
is a typical choice, but as petroleum has become more and more expensive,
the option of oil additives has become a less attractive option. And
although additive lubricity is highly desirable, it does not compensate for
the various shortcomings of today's spin on oil filter. Motorcycle oil
filters that are even more smaller require more help keeping re-circulating
the engine oil to its cleanest.
The use of magnetic oil filters at each oil change plays an important role
for the complete removal of all steel particulate from the engine oil. These
filters remove even the smallest steel particles (as small as 2-micron size)
as well as the other destructive debris from the engine oil.
Design
The design of a magnetic oil filter utilizes a focused magnetic force
field, which amplifies its powerful magnets, to generate a strong force
required to forcibly remove the smallest particles below 20-micron from the
oil flow, and hold increasingly smaller particles against the pressure of
oil flow velocity. In order to remove the smallest particles of steel from
the oil system, the magnets of a magnetic oil filter must have sufficient
energy to hold extremely fine particles against the oil flow velocity.
These filters employ a technology, which redirects the magnetic energy
typically present on the far side of the magnet towards the inner side of
the filter canister. The flux amplifier has to be of a precise thickness to
maximize the magnetic field and the circumference must be adjusted to
provide for the manufacturing variances to effect in a perfect fit & the
alignment of series of magnets to the filter canister. This centers the
utmost amount of magnetic energy within the flow of oil.
In general, the magnetic oil filters operate by simply placing it onto the
outer side of filter housing where the magnetic force mechanically snaps it
into place. After this the ultra strong magnetic force come into play that
forcibly trap the unwanted particles "locked" against the inside
walls of the conventional filter.
Advantages of Magnetic Oil Filter
- Extend engine life
- Provides more horse power for the drive train
- Superior filter function
- Improved oil lubricity and additive lubricity
- Lower temperatures
- Improved emissions
- Improve mileage
- Reduce spark plug fouling
Filter Magnets
Though
the use of magnets to collect the particles of iron from engine oil looks
simple, just placing a magnet in the oil pan does not deliver sufficient
effect. Due to the features and characteristics of motor oil, the metallic
particles in circulating oil will not be attracted by the magnet except in
the case there is a direct contact with the surface of magnet.
When oil is stationary, only the particles, which immediately surround the
magnet are attracted. A magnet, which is placed in the differential gear box
will be more effective and strong in attracting metal particles. In
automatic transmission fluids, iron particles are absorbed more efficiently
in case the magnet is placed close to the oil cooler intake instead of
placing it merely on the oil pan. There is an existing device that is
developed to remove particles from the automatic transmission fluid.
The route, which the engine oil drives through an oil filter, forms the
perfect position for a particle-attracting magnet. The most effective
magnets in particle removal are those that have alternating opposing poles
(N=North and S=South).
