An engine air cleaner includes a cleaner element unit is housed within the upper cover body, and a skirt wall of the upper cover body extends further downward than the suction opening. A seal packing and the cleaner element unit are superimposed and fitted onto an outer periphery of an intake passage within the cleaner cover body. The seal packing is provided with a retaining projection that is tightly engaged with the intake passage. An air cleaner is disposed to be side by side with one side of the engine, a lower part of the cleaner cover body is joined integrally to and supported on the engine together with a carburetor via a pair of connecting bolts, and a reinforcing vertical wall portion of the cleaner cover body facing the engine across a gap is joined integrally to and supported on the engine via another connecting bolt.

Engine air cleaner and device for mounting air cleaner on engine

An air-cooled engine () has a fan cover () for covering a cooling fan (). The cover () is composed of a fan-cover peripheral wall () for covering the outside of the cooling fan (), and a top board () for closing off one end of the fan-cover peripheral wall (). The fan-cover peripheral wall () has an internally disposed guiding duct () for guiding cooling air (Wi) from the cooling fan () to an engine main body (). A first fastening member () secures a portion of the external part of the fan-cover peripheral wall () that is proximal to the guiding duct () to a casing () of the engine main body (). A second fastening member () extends from the casing () and through the fan-cover peripheral wall (), and secures a top board () in a portion that is at a distance from the guiding duct ().

Air-cooled engine

The invention provides an air-cleaner filter material for an internal combustion engine, which comprises a dust-collecting layer comprising a melt-blown nonwoven fabric having a maximum pore size of 100 &#x3bc;m or less and a dust-retaining layer arranged upstream of the dust-collecting layer and laminated integrally by heat fusion with, the dust-collecting layer, comprising a thermal-bond nonwoven fabric having fibers with two or more fiber diameters arranged in the order of increasing the proportion of smaller fiber diameter in the direction from the upstream to downstream side, wherein the in-plane of the filter material has a portion of high fiber density and a portion of low fiber density, and the portion of high fiber density occurs in a lattice pattern.
