Abstract: The invention relates to an air cleaner housing for a vehicle, comprising an outer and an inner circumferential wall, and a space therebetween adapted to house at least one filter element for filtering air, wherein the inner circumferential wall is provided with openings to allow filtered air to pass radially inwardly through the inner circumferential wall. The air cleaner housing comprises a first end and an open second end for fluidly connecting the air cleaner housing to a turbo, the open second end being located opposite the first end. The air cleaner housing comprises a resonator, wherein the entire resonator is encircled by the inner circumferential wall such that air entering through the inner circumferential wall passes on the outside of the resonator to and through the open second end.

Abstract: The invention relates to a filter element for mounting in an air cleaner housing of a vehicle. The filter element comprises a circumferential filtering wall through which air is allowed to enter. The filter element also comprises a first end and an open second end for fluidly connecting the filter element to a turbo. The open second end is located opposite the first end. The circumferential filtering wall extends from the first end towards the open second end. The filter element further comprises a resonator. The entire resonator is encircled by the circumferential filtering wall such that air entering through the circumferential filtering wall passes on the outside of the resonator to and through the open second end.

Abstract: The present invention relates to a coated cutting insert with excellent toughness properties particularly useful for toughness demanding short hole drilling in general steel materials and a method of making the same. The inserts comprise a substrate and a coating. The substrate comprises WC, from about 8 to about 11 wt-% Co and from about 0.2 to about 0.5 wt-% Cr with an average WC-grain size of from about 0.5 to about 1.5 ?m and a CW-ratio of from about 0.80 to about 0.90. The coating comprises a first (innermost) layer of TiCxNyOz with a thickness less than about 1.5 ?m, a layer of TiCxNyOz with a thickness of from about 1 to about 8 ?m with columnar grains, a layer of fine-grained grain ?-Al2O3 with a thickness of from about 0.5 to about 5 ?m and a further layer less than about 1 ?m thick of TiCxNyOz whereby at the rake face the outermost TiCxNyOz-layer and Al2O3-layer are fully or partly missing.

Abstract: The present invention relates to a coated cutting insert with excellent toughness properties particularly useful for toughness demanding short hole drilling in low alloy and stainless steels and a method of making the same. The inserts comprise a substrate and a coating. The substrate comprises WC, from about 8 to about 11 wt-% Co and from about 0.2 to about 0.5 wt-% Cr with an average WC-grain size of from about 0.5 to about 1.5 ?m and a CW-ratio of from about 0.80 to about 0.90. The coating comprises a laminar, multilayered structure of TiN+Ti1-xAlxN+TiN+Ti1-xAlxN+TiN . . . in polycrystalline, non-repetitive form, with x being from about 0.4 to about 0.6 with a thickness of the individual TiN—or Ti1-xAlxN-layers of from about 1 to about 30 nm varying essentially at random and with a total thickness of the multilayered coating of from about 1 to about 5 ?m. The layers are deposited using arc evaporation technique.

Abstract: Coated cemented carbide inserts for short hole drilling in steel at high speed and moderate feed is disclosed. The cemented carbide includes WC, about 2-10 wt-% Co, and about 4-12 wt-% cubic carbides of metals from groups IVa, Va or VIa. The Co-binder phase is highly alloyed with W with a CW-ratio of about 0.75-0.90. The insert has a binder phase enriched and essentially cubic carbide free surface zone of a thickness of less than about 20 ?m. Along a line essentially bisecting the edge in the direction from the edge to the centre of the insert, a binder phase content increases essentially monotonously until it reaches the bulk composition. Binder phase content at the edge in vol-% is about 0.65-0.75 times binder phase content of the bulk. The depth of the binder phase depletion is about 100-300 ?m.
