AUTOMOTIVE AIR FILTERS

AUTOMOTIVE   AIR   FILTERS

Abstract

All Modern cars are fitted with an Air cleaner on the Carburetor intake. It’s Most Important function to prevent dust and other particles from getting in to the carburetor and engine cylinder.
A normal car engine uses about 100-200 Cu.ft of air a minute , and a filter is essential to prevent particles of dust or dirt blocking air jets and causing wear to pistons and cylinder and bores.
Filter offers a resistance to airflow and will affect carburetor performance as they become blocked with dirt. They should be replaced or cleaned at regular intervals -say every 12,000 Miles.
The Air filter also acts as a silencer. The filter itself muffles the hissing noise from the carburetor air intake. The intake tube are Designed to damp out the resonance of pressure fluctuations in the inlet manifold.
There are several types of air filters their shapes and sizes are generally directed by engine-compartment space and air flow. A good air filter reduces the noise considerably.
Generally air filter in use today have paper element which can be discarded and replaced when no longer serviceable.
The latest designs have plastic units which are light, corrosion free and less resonant than pressed steel units.
Some air filters incorporate temperature control to supply an engine with air at constant temperature.
Both air flow and dirt protection are critical to engine performance.  For this reason a consumer should always evaluate an air filter based on both its filtration efficiency and air flow capabilities. It is very easy to design an air filter that exhibits high airflow simply by reducing its filtration to unacceptable levels.  As the “look” of a  air filter has become popular.
