The effect of EGR adopting different air filters on diesel engines

Every internal combustion engine needs supply of air. This air is required to be dirt free dry clean and cool. Unfiltered air can speedily wear out an engine. In a short period of time can drop the engine compression and power and begin to emit heavy smoke. As the air filter dust builds a film the holes in the filter medium becomes smaller and the filter becomes more efficient at trapping dirt. As the filter traps dirt it is difficult for the air to pass through the filter and restrictions increase in the air intake system. Restriction of air through filter usually remains low for most of the filter's service life but increases rapidly at the end. The value of air filter restriction is the key parameter to be used considering filter replacement. The present book is focused on the engine filter technologies and their effect on its performance emissions and fuel economy.
