I need to know where the exhaust emissions are located under the hood.?

Question

I need to know where the positive crankcase valve, exhaust gas recircualtion, evaporative emission system, air injection system and thermostatic air cleaner is, If someone can give me a website of a diagram that shows where all these parts are located, or if you can tell me, I would GREATLY appreciate it, I have to take a State Inspection test, and i need to know where all these parts are located, thank you very much!!

Oh yah, another thing, im not to sure what kind of vehicle im inspection, this dude made a good point, AND they dont let you look at the sticker, they're ***** like that,

Answer 1

There is a diagram under the hood on a sticker. If you don't describe what kind of car you have, how will anyone be able to answer accurately? The PCV valve will most likely be on a valve cover. The EGR valve will be on the intake manifold and have a vaccum line going to it. It looks like a little flying saucer. Best of luck.
