AIR FILTERS
Our broad range of FRAMŽ Air Filters helps our customers to meet their specific
application requirements providing a superior level of protection from dust and
dirt, preventing damage to valves, cylinders, rings, rockers and bearings. It
is recommended that air filters should be checked with every oil change.
What does it do?
The engine air filter could be compared to the automobile's lungs. It is
designed to eliminate the dust contained in the ambient air taken in by the
engine. Simplistically an Internal Combustion Engine functions by drawing in
air to be mixed with fuel in the right proportions and at the right instant
this mixture is ignited providing the power to drive the engine, vehicle or
equipment attached.
The air is drawn in from the atmosphere that contains abrasive dirt and sooty
exhaust particles. If not filtered these particles will cause rapid wear on
internal engine components and ultimately considerably shorten engine life. It
takes a very small amount of road dust to ruin an engine, only a cupful,
approx. 220 grams would do the job. As a rough measure, for every gallon of
fuel burned in the combustion process 10 to 12,000 litres of air are consumed.
This gives an idea of the magnitude of the job to be done by the Air Filter or
Air cleaner as it is sometimes called.
Although the principal reason for the Air Filter is to reduce intake of harmful
and contaminant (abrasive dust, airborne exhaust soot, etc.) it often has other
roles. In nearly all cases a properly designed Air Filter housing not only
carries the filtration cartridge but by careful design of the intake system can
reduce intake noise, which is considerable. Air Filter housings also play a
large part in reducing water ingress, which can cause considerable engine
damage, by allowing the designer to place the air intake at the most
advantageous position. In Heavy Duty Commercial Vehicles in particular Air
Filter Housings are designed to cause precipitation of excess water prior to
the air stream arriving at the filtering element. Another role of the Air
Filter is to provide a carrier for Air Intake Temperature Control sensors and
diverted valves, particularly important in controlling emissions as well as
assisting in optimising combustion efficiency. As part of the air intake system
on a car, for example, the Air Filter and in particular the intake tube can
often be tuned to minimise power loss.
If the air filter is dirty, three things can happen, all of them bad: reduced
engine power (a key to peak engine performance is the flow of clean air to the
ignition point), decreased throttle response and increased engine wear.
