What is Exhaust and intake valve?
As an air/fuel mixture is drawn into the intake ports, intake valves open to allow the mixture to enter the cylinder. On the exhaust stroke of an engine, the exhaust valves open, allowing the burned air/fuel mixture to exit out the exhaust ports. Intake valves are larger than exhaust valves, and are able to be found on the "cold" or intake side of the cylinder head(s).
What is the function of a camshaft?

What describes the position of intake and exhaust valves during the most powerful stage in a four-cycle gas engine?
-intake: exhaust closed, intake open -compression: exhaust closed, intake closed -combustion: exhaust closed, intake closed -exhaust: exhaust open, intake closed
How can you identify the intake valve from the exhaust valve with the heads on?
The exhaust valves will be located closest to the exhaust manifold side of the head & are always smaller in diameter than intake valves. Also if any are open @ the time you will see the carbon build up around the exhaust valves where as the intakes will be considerably cleaner.

What are valves responsiable for?
Open/close intake & exhaust ports. let in fuel. let out gases after combustion.
What is Purpose of the cam shaft?
to open and close the intake and exhaust valves in accordance with piston and crankshaft position
When the intake and exhaust valves are both open at the same time that length of time is called?
Valve overlap.
When do the intake valves of an engine open?
A intake valve open when the piston reaches the top of the cylinder and just after the exhaust valve closes. It allow fuel and air to enter the engine cylinder.
What is meant by the term valve overlap?
There is a short time between the exhaust and intake stroke where all the valves are slightly open at the same time. This period of time is called valve overlap. This is because the intake valves are just starting to open as the exhaust valves are just finishing closing. This is done so flow through the engine can be maintained at engine operating speeds.
Function of valve?
The valves in a car engine are opened and closed by a cam shaft driven by the engine crankshaft. they allow the flow of gases and fuel into the engine and the burnt gases out of the engine into the exhaust system.
