Air cleaner - RA0900KE20010X(09-0010)

The air cleaner is positioned on the mixture control unit. A seal is installed between air cleaner and mixture control unit. Access to the mixture regulating screw is obtained, if necessary, through a recess in the top part of the air cleaner.

Air cleaners trap the dust in the intake air and thus prevent engine wear. Dust levels on paved roads are approx. 1 g of dust over a distance of 1000 kilometers. The dust content may in extreme cases rise by 40 times on unpaved roads.

The intake scoop is positioned next to the radiator in such a way that as little dust as possible is drawn in.

A further task of the air cleaner is to dampen the intake noise so as to satisfy legal requirements in respect of overall vehicle noise.

The intake air temperature sensor (B17/2 or B17/1) is positioned at the air cleaner housing or in the intake scoop, depending on version. This influences the KE injection system or the EZL ignition system, respectively.

The air cleaner housing is made of plastic (except engines 102.961, 116, 117).

The air cleaner is harmonized to the engine in order to optimize engine output, fuel consumption, noise insulation.

The paper air cleaner element should be serviced regularly. The perforated metal sheet in the air filter element acts as a reinforcement so that the filter segments also withstand frequent cleaning (knocking out, blowing clean with compressed air) without damage. The filtering effect is not altered by the perforated metal sheet.
