Filter element comprising two offset outlets in communication with filter inner space, as well| as corresponding housing
A filter element is provided having a tubular shape defining an inner space, a first outlet in communication with the inner space and a second outlet in communication with the inner space, wherein the second outlet has an offset position in relation to the first outlet in a transversal direction of the filter element. Also provided is a filter housing having an inner housing space adapted to receive a tubular filter element, the filter housing having an inlet, a first outlet located in a first end of the filter housing, and a second outlet located in a second end of the filter housing, wherein the second end is located opposite to the first end in relation to the inner housing space.
1. An air filter element having a tubular shape defining an inner space, the filter element having a first end panel at a first end and a second end panel at a second end located opposite to the first end in relation to a longitudinal direction of the filter element, a first air outlet located in the first end panel and in communication with the inner space and a second air outlet located in the second end panel and in communication with the inner space, wherein the first air outlet has a first centre axis and the second air outlet has a second centre axis, wherein the first centre axis and the second centre axis are parallel to one another, wherein the first centre axis and the second centre axis are arranged at an offset position in relation to one another in a direction perpendicular to the extension of the first and second centre axis, wherein a cross-sectional area of the second air outlet is smaller than a cross-sectional area of the first air outlet, wherein the second air outlet extends axially through the second end panel from the inner space and out from the filter element and, wherein a cross-sectional shape and dimension of the first air outlet is the same as a cross-sectional shape and dimension of the inner space.
2. The air filter element according to claim 1 , wherein the offset position involves a distance-in the transversal direction of the filter element.
3. The air filter element according to claim 1 , wherein the offset position is a distance as seen in the transversal direction of the filter element between a centre point in the first air outlet and a centre point in the second air outlet.
4. The air filter element according to claim 1 , wherein the filter element has a cross-sectional shape with a first extension in a first direction and a second extension in a second direction which is perpendicular to the first direction.
5. The air filter element according to claim 4 , wherein the first extension is greater than the second extension such that the cross-sectional shape is oval.
6. The air filter element according to claim 5 , wherein the offset position of the second air outlet in relation to the first air outlet is along the first extension direction.
7. The air filter element according to claim 1 , wherein the filter element has a maximum available offset position which equals to a length corresponding to an extension in a first direction of the inner space subtracted by half of an extension in a first direction of an outer periphery of the second air outlet and by half of an extension in a first direction of an outer periphery of the first air outlet, wherein the offset position is at least 50% of the maximum available offset position.
8. The air filter element according to claim 1 , wherein the first air outlet and/or the second air outlet has a cylindrical cross-section.
9. The air filter element according to claim 1 , wherein the first air outlet is located coaxially with the filter element.
10. The air filter element according to claim 1 , wherein a cross-sectional area of the second air outlet is smaller than a cross-sectional area of the inner space.
11. An internal combustion engine comprising an air filter element according to claim 1 .
12. A vehicle comprising an internal combustion engine according to claim 11 .
