File talk:Navistar DT engine.jpg

Replaceability=No. There are very limited opportunities to create free images of this engine, especially fully exposed as in this image, as opposed to installed in a truck, as photos of this engine removed or not installed in a truck are rare. Also, this image provides much more clarity and detail than any photograph made of the engine in a truck or bus, where the engine would be obscured by hoses, tubes, wires, and vehicle structures, would be. Finally, a photo of the engine in a truck or bus would show significant dirt and weathering, further obscuring the technical and mechanical details.

This image is from the same source as images in International Durastar The company states in its FAQs http://www.internationaldelivers.com/site_layout/absolutefm/afmviewfaq.asp?faqid=7 that images may be used in a manner that is not detrimental to the company.--Lpimlott 04:16, 15 November 2007 (UTC)
