The diagramme below is an image map which has been treated so that each part of the motor has its own label. Move your mouse over the diagramme, hold it still for a moment and an "Alt Text" label of the part you have highlighted will appear. If you click on that part of the image map, you will be taken to a page which describes that part in more detail, or shows a picture. Use your browser's "Back" button to return. *
* If the part you highlighted doesn't take you anywhere when you click on it, sorry; it takes time to build a web site!
