A few photos of under bonnet engine parts in the link below. Some may not have looked too closely, it's just good to know a few basics.
I'm confident that I've named some of them correctly, others have a question mark after my guess. Anyone with more knowledge - please tell me the slide number and new description and I'll change it.
