The intake valves line up with the intake runners on the intake manifold. The exhaust valves line up with the exhaust runners on the exhaust manifold or headers. With #1 at tdc you can set 1,2,5,7 intake and 1,3,4,8 exhaust valves. Rotate the engine one revolution to #6 tdc and set the remaining valves.
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
A Dodge 5.2L has one exhaust valve and one intake valve per cylinder. That would make a total of sixteen valves.
8v.....of course.acually it is the number of valves in the head . An 8v has 2 per cylinder( one intake and one exhaust) a 16v has 4 valves per( 2 intake and 2 exhaust).
That's an easy one. Take the rocker box's, (valve covers) off. The valves that line up with the intake runners, are intakes, and the ones that line up with the exhaust, are exhaust. If the heads are off, always the larger valve, is intake.
Four stroke engines must have at least 2 valves: one exhaust and one intake. Most modern engines are going to 4 valves per cylinder to allow the intake and exhaust strokes to be more efficient.
Yes, there are 2 camshafts on a 1.8T GTI. The engine uses a 20 valve design, meaning 5 valves per cylinder. For each cylinder 3 valves are intake valves and 2 valves are exhaust valves. One camshaft drives the intake valves and the other camshaft drives the exhaust valves
Depends on engine size. Typically two valves per cylinder. One intake and one exhaust. Some higher performance applications can have four valves per cylinder.
At TDC of the compression stroke for cyl #1, the cam lobes will be in a position such that they are putting no pressure on the valves, and valves are closed. At TDC of the exhaust stroke for cyl #1, the lobes will be in a position such that intake and exhaust valves may be open. Exhaust will be closing, and intake will be opening. There are two revolutions for the crank for one of the cam. TDC usually refers to TDC of the compression stroke, when valves are closed. This is when combustion/spark occurs, and is when the valves are adjusted on most engines.
Close one hole of your nose and try to breath in. Feel any difference. Coming back to the subject. By increasing the # of valves you get the below features. a) better combustion chamber shape, resulting in better combustion, resulting in better power and fuel economy. There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. As the first two responders pointed out, you have intake valves, which let air in a diesel, or air plus gas in a gasoline engine, into the cylinder; and exhaust valves, which let the spent gases leave the cylinder. One important thing multiple valves can do for you is to let the spark plug be put in the center of the cylinder, from where the flame front can radiate evenly through the chamber. A 16-valve engine (if it's a 4-cylinder) has two intake and two exhaust valves. A 16-valve engine could also be an 8-cylinder engine with 1 intake and 1 exhaust valve per cylinder. A 12-valve engine has two intake and one exhaust valve (if it's a 4 cylinder engine). a 12-valve engine may also be a 6-cylinder engine with 1 intake and 1 exhaust valve per cylinder. evan was here
12. one intake and one exhaust valve for ea. cylinder. The 3.8 is a V6 engine.
intake valves are the larger valves or if you count from from either end its number 2,3,6,&7 valve
