Combustion engines require clean intake air for optimal performance. Dirt is aggressive; if pollutants such as soot or dust get into the combustion chamber, pitting may occur. Pitting on the cylinder heads, for example, causes premature wear on the engine. Pitting could also impair the function of electronic parts located between the suction and the combustion chamber.MANN+HUMMEL core activities in the development of air filter systems:• Filtration• Flow optimisation with regard to pressure loss• Acoustics including sound design• Styling• Integration of various functions.We are constantly setting new standards with continuous development in these areas. We offer expert solutions forwide-ranging requirements in the passenger car, HGV and in the industrial sectors. Examples include construction and agricultural machinery.
