[edit] RAM
Could someone explain, why is this page linked to from RAM? --ZeroOne 21:37, 14 Nov 2004 (UTC)
- It was someone's idea to link from "ram", methinks, as in "ram-air". I'll kill it. --SFoskett 17:24, Nov 15, 2004 (UTC)
- That's right. The ram air intake is one method of increasing the power output of the engine. It just forces more air into the intake so that there can be more complete combustion and so that more fuel can also be injected. It's a bit different from supercharging and turbocharging because supercharging uses the engine to pump more air into itself while turbocharging uses the exhaust fumes to pump the air. --TChak 09:24, Dec 2, 2004 (EST)
Can anyone suggest what can cause the Intake Manifold to Crack?
- Intake? Or Exhaust? Exhausts crack when cold water drips on them when they are hot. —The preceding unsigned comment was added by 142.232.48.168 (talk) 16:20, 5 January 2007 (UTC).
[edit] Etymology
Where did the idea that "manifold" means "hand-shaped'? come from? Manifold, as an adjective, means "consisting of or operating many of one kind combined." It comes from Old English "manigfeald" - (manig-many, feald-fold) (def. and etymology from Mirriam Webster's College Dictionary, 10th ed.). It's been used for ages as an adjective, for things that bear absolutely no resemblance to a hand of any sort (a manifold bell-pull, for instance - a single cord that rings several bells in different parts of a house; a manifold pipe would be a pipe that delivers or drains water to or from many parts of a house).
The terms arose in their present form as engines began featuring devices called "manifold intakes" and "manifold exhausts." In other words, an intake that services more than one cylinder, and an exhaust that services more than one cylinder. As engines developed, and engineers and mechanics got their hands on the jargon, "manifold intake" and "manifold exhaust" became "intake manifold" and "exhaust manifold," respectively. Hands (other than the hands that can get burned when you touch a hot exhaust header) have nothing to do with it.
- Exactly! I hunted for ages to find my wikipedia login name to say exactly the same thing. Otherwise the Bible's mentioning of the "manifold wisdom of God" would be rather hilarious. I'm going to BE BOLD and make the edit. - Robg —The preceding unsigned comment was added by Robg (talk • contribs).
[edit] Best material?
What is the best material to build an exhaust manifold out of? For heat dissapation & longevity, etc. Would this be cast iron, steal, ceramic coated etc? —Preceding unsigned comment added by 24.70.196.23 (talk) 04:23, 4 September 2007 (UTC)
Did someone just remove the "manifold is gay" below the intro? —Preceding unsigned comment added by 209.89.168.64 (talk) 05:54, 11 January 2008 (UTC)
