대표청구항 ▼

1. A cylinder bore having a longitudinal axis and a cylindrical wall extending along the longitudinal axis, the cylindrical wall comprising: a first end portions having a first diameter; anda middle portion axially adjacent to the first end portion, the middle portion having a second diameter greater than the first diameter and a plurality of parallel, alternating teeth and grooves formed therein to provide a surface roughness of the middle portion greater than a surface roughness of the first end portion. 2. The cylinder bore of claim 1, further comprising a second end portion axially adjacent to the middle portion at an end opposite from the first end portion and having a third diameter smaller than the second diameter. 3. The cylinder bore of claim 1, wherein an axial length ratio of the middle portion to the first end portions is of 10:1 to 50:1. 4. The cylinder bore of claim 2, wherein the first end portion has a different axial length than the second end portion. 5. The cylinder bore of claim 2, wherein at least one of the first and second end portions has an axial length that is 2 to 15 percent of a length of the middle portion. 6. The cylinder bore of claim 1, wherein each groove of the plurality of teeth and grooves includes a rectangular cross-section. 7. The cylinder bore of claim 1, wherein each groove of the plurality of teeth and grooves includes a trapezoid cross-section. 8. The cylinder bore of claim 1, wherein the middle portion further comprises a metal coating covering the plurality of teeth and grooves. 9. A cylinder bore having a longitudinal axis and a cylindrical wall extending along the longitudinal axis, the cylindrical wall including first and second end portions having a first diameter and a middle portion positioned between the first and second end portions and having a second diameter greater than the first diameter, the middle portion having a plurality of parallel, alternating teeth and grooves formed therein. 10. The cylinder bore of claim 9, wherein the first end portion has a different axial length relative to the second end portion. 11. A method of forming a cylinder bore having a longitudinal axis and a cylindrical wall extending along the longitudinal axis, the cylindrical wall including first and second end portions and a middle portion positioned between the first and second end portions, the method comprising: forming the middle portion to have a diameter greater than a diameter of the first portion and a diameter the second portion and having a plurality of parallel, alternating teeth and grooves formed therein. 12. The method of claim 11, wherein the alternating grooves and teeth are formed with a rectangular cross-section. 13. The method of claim 11, further comprising wiper blading the teeth with an angular force at an angle to the longitudinal axis of the cylinder bore, the angle being greater than zero and smaller than 90 degrees. 14. The method of claim 11, further comprising applying a coating layer to the alternating teeth and grooves of the middle portion.
