This technology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Automotive alternator.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

This technology image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.

This specific drawing from a vehicle engineering textbook has been explicitly found ineligible for copyright in Finland by the government-appointed Copyright Council in its opinion TN 2011:12 (in Finnish) (Request for comment). Unofficial translation of the specific reasoning:

In the drawing, that illustrates the structure of an automobile's alternator, the subject has been drawn in a style that has been commonly adopted in the field of vehicle engineering.

The drawing illustrates a conventional part of an automobile, whose original portrayal is significantly limited by the part's conventional shape, and the clear and technically sufficiently detailed illustration as required by appropriate use in a textbook. There have not been several alternative ways to illustrate the same subject, when striving for a clear and technically correct expression.

The Copyright Council sees, that the drawing does not demonstrate its creator's creative personal decisions to such degree, that no one else would arrive at the same end result, when setting out to draw the same subject. The Copyright Council sees, that the drawing in question is not independent and original to such degree, that it would exceed the threshold of originality.

This work is ineligible for copyright and therefore in the public domain because it consists entirely of information that is common property and contains no original authorship.
