what's the function of a car valve???????????
Cylinder head valves come in many designs and combinations. Their may be two, three or four valves in the head and combustion chamber that open and to let air and fuel in while the piston compresses the mixture and is ignited near top dead center. When the piston is near bottom dead center the exhaust valves open where the piston pushes the spent gasses out underneath the open exhaust valve. As the piston nears the top of the exhaust stroke, the intake valve opens to allow the air/fuel to enter the combustion chamber and cylinder bore. As the piston sweeps down vacuum is created in the cylinder and more fuel / air enters. When the piston reaches the bottom of the intake stroke, the intake valve closes in preparation for the compression stroke. Go to the Wikipedia Encyclopedia ot How Stuff Works to see how a four stroke engine operates. You'll see what the valves look like and how they work.
valve A way to turn on or a off of anything Liquid or gas or air works same as a switch does for power it controls flow of
the relatively valve would be unscrewed from the valve stem and adjusted. If t's the valve stem that desires changing that's achieved from interior the wheel/tyre blend. it would desire to be achieveable to deflate the tyre, push one section inwards off the rim and get to the valve stem, even yet it relatively is lots extra handy to take it to a tyre depot and characteristic it finished precise. the actual undertaking with a DIY job is getting the tyre sealed on the rim back. With an air line it relatively is undemanding to place air in quickly adequate to reseat the tyre, with a foot pump it relatively is totally very nearly impossible
Valve is more like a door, it's has a job to let in a thing and let out a thing. In car, valve is locate to the combustion chamber, intake and outtake. It's configure in SOHC and DOHC, in Single Over Head Camshaft there is 1 valve in and out each cylinder, in DOHC there is 2 intake and 2 outtake, even some engine has 3 intake and 2 outtake. The intake valve job is to let in the air fuel mixture to the combustion chamber, while the outtake valve job is to let out the burned air fuel mixture. By valve, the combustion chamber can be isolated from any leak such as air or compression lost that may disturb ignition sequence and emission control.
It is the stopper for the combustion chamber, the intake one lets stuff in and the exhaust one lets stuff out.
