what is the function of valves in a car ?

Answer 1

Valve are opened an closed by the cam. (bumpy thing) They open to let fuel air in, close to compress and burn the mixture and open to expell the exhaust gases. There you have it. Suck,squeeze,pop, fuie!!!

Answer 2

Just like any other valve they let something in (usually a gas or a liquid - in a car engine its a petrol/air mixture) but won't let it out until the valve (or another valve) is opened. A valve is like a one-way gate

Answer 3

The valves of a car take in cool air and let out exhaust fumes

Answer 4

They let the fuel/air mixture into and the burnt gases out of the cylinder. Generally there are 2 per cylinder, one for inlet and one for outlet, although broadly speaking the more valves the better the performance as the inlet/outlet process becomes more efficient.

Answer 5

The valves allow the fuel mixture to go into the cylinders and the exhaust from the burnt fuel mixture to go out.

Answer 6

ATF for automobiles is basically approximately universally understood to intend computerized transmission fluid. No clue what the "ATF valve" could be, according to hazard somebody is making an attempt to sell you something you do no longer fairly desire?

Answer 8

They are to let the air (and in most petrol engines the fuel also) into the combustion chamber, then to seal the combustion chamber, then to let the exhaust gases out.
