As works K&N the filter. Myths and a reality.
At external survey of the filter the big apertures in a filter material are visible is the main reason of high throughput of a stream of air. The filter is executed by layers from a surgical cotton gauze with the oil impregnation clamped between an aluminum grid. The special oil structure which is in a cotton gauze doesn't limit throughput and during too time provides a qualitative filtration of an air stream. It is a basis of unique system of a filtration! Dust particles in the air stream, drawn to the filter, have a negative charge and passing through filtering element (like magnet action) are drawn and join the impregnated cotton gauze having a positive charge. At the big congestion of the detained particles on outer side of the filter of an aperture in a gauze fabric remain opened. This external level of a dust and sand becomes a secondary element of a filtration of entering particles and high throughput is thus provided. This simple, but very effective secondary filter – a basis of long service of the filter, in many cases to 10 times longer, than the usual filter. 12000 kilometers the filter don't demand service and it ‘ norm ’. Clearing is spent on run or if, the saved up layer of pollution makes 2mm – 3mm.
Myths about air filters K&N
Exists чень popularly judgement about unsatisfactory ability of a filtration of sports filters at the expense of the reduced resistance to an air stream. It in a root incorrectly. Efficiency of a filtration of regular air filters depends on porosity of a material from which they are made. The porosity, the better filtering ability of an element is less. The problem of the big resistance consists in it to an air stream.
The greased cotton filters used in K&N function absolutely on another, than regular air system. In manufacture of filters K&N the proved scientific principles which define how the air filter deletes particles of a dirt from an air current are applied. The first of these principles is known as "interception" which is applied to the particles of a dirt traveling with an air current. The air stream will always find the shortest path and as air passes through the fibres of the filter some of particles will contact with fibres and will be grasped". These particles will be kept in fibres of a filtering element at the expense of application of special impregnation.
Other principle is known as impaction which mainly influences the big or heavier particles of a dirt. Impaction is when inertia or an impulse force a particle to deviate the general air stream. In other words, heavy particles don't follow an air current by filter fibres, and instead they get directly to fibres.
The most important principle for filter K&N working out are laws of physics which operate movement of very small particles of a dirt. Small particles are influenced by forces in an air current. For example, forces of high-speed changes, pressure changes, a storm caused by other particles and interaction with air molecules force very small particles to move casually and chaotically, contrary to the basic air stream. As result these particles don't follow an air current, and their random motion forces to face filter fibres.
The usual paper filter is capable to filter an air stream directly one surface. Unlike usual filters Element K&N has большее advantage, thanks to the multilayered impregnated surface and the best configuration of an element. The given feature allows air filter K&N to detain большее quantity of a dust.
What do air filters? Filters clear air before it gets to the engine. The more cold air you can tire out in the engine, the it is more than capacity will give out, provided that топливовоздушная the mix is optimum. It follows from this that if you replace the standard air filter that can pass большее quantity of air through itself, at you capacity of the motor, and a miracle in it any will raise isn't present!
Proof in relation to a moisture and a dirt – the Air stream will pass (the filter will breathe) even if the filtering element completely will become soiled or will become wet that it is impossible to tell about polluting particles and a moisture they won't pass further buttered impregnation.
Capacity – Even on the standard engine not subjected to completion filter replacement on K&N with the minimum aerodynamic resistance of air will give the chance to it is high-grade to breathe. You will get a rise in capacity from 5 to 10 h.p. depending on degree of completion of the motor and improve a purge of your engine. For forced and not only engines it is additional possibility ~ on 1 сек to improve result of dispersal to 100.
Durability – Buying the filter, you are released from necessity to change its everyone 15000 so, buy it on all life. The filter has a guarantee on 1 600 000 km, washes special structure in case of pollution after 75,000-160,000 and again as new can be used without loss of the initial properties. Besides filters K&N prolong also life to your motor, after all one of the main qualities of the good filter it not to admit hit of the smallest particles in the engine, thanks to the impregnation and a filtering element the filter detains all smallest particles at the greatest possible low aerodynamic resistance, thereby preserves system from засора and piston against possible destructions.
Induction noise is that costs, if you the real fan, and for you possibility to listen as your motor – equivalently music breathes.
K&N These are sports air filters requirements to which by manufacture are very high, after all except макс protection of the engine against hit in it of the smallest particles, sand and a dust, you receive also advantage in capacity and dynamics and as possibility to make your bike not similar to others!
