All About Car's Valve Train & Cylinder Head Parts

Valve Train

It is a mechanical system which would control the working of the valves in an internal combustion engine. The sequence of components would transmit the motion throughout the assembly. A conventional which would reciprocate the internal combustion engine would utilize the valves to control the flow of the air/fuel admix into and out of the combustion chamber.

Cylinder Head

It is generally situated on the top of the engine block. It would also serve as housing for the constituents like the intake and exhaust valves, springs and lifters as well as the combustion chamber.

Are you searching for the different types of valve train & cylinder head? Then don’t worry! All you have to do is to have a look below and then all your doubts regarding its types would be cleared.

Cylinder Head:

Have a look at three types of cylinder heads:

1. Flathead Cylinder Heads - The first and the foremost type is the flathead cylinder head. Their main function is to protect the cylinder block as well as no moving parts. It is these cylinder heads which would not allow an efficient air flow, and that’s the reason why they might provide bad engine performance.
2. Overhead Valve Cylinder Heads - This type of cylinder heads would be superior to the flathead cylinder heads. There are camshafts above the overhead valve cylinder heads.
3. Overhead Camshaft Cylinder Heads - This type is one of the most advanced designs of cylinder heads. The camshaft would be inside the cylinder head of the overhead camshaft cylinder heads and thus they would also eliminate the need for pushrods. It would then provide a better airflow and at the same time would increase the efficiency of the engine.

Are you searching how do the valve train & cylinder head actually work? Then all you have to do is to have a look below and then you will be able to understand everything.

Valve Train Working:

• The main role of the valve train would be to open as well as close the valves and for some older models, it would work in controlling the fuel output of the injectors. There are a lot of heavy-duty engines which we work with are 4 valve engines, which would mean that there are four valves in each cylinder: 2 intake and 2 exhaust. A lot of different components would be used by the valve train depending upon the type, push or lift up from the valves. It would then allow air into as well as out from the cylinder. There is an injector in the middle of the valves, which would be pushed down so that it can inject the fuel into the cylinder. The timing for this process would be very precise. The engines which are new would utilize the electrical signals to cue the injector, rather than the mechanical valve train, which would make that process even more precise. 

Working of Cylinder Head:

• Cylinder head is the place where a great deal of the action for running your engine would take place. It would contain a combustion chamber where the quick burning of the fuel as well as air which would move the pistons would start occurring. This can only take place when the cylinder head would be connected to the intake as well as to the exhaust manifolds. It is the intake manifold which would feed the air into the head through the intake ports, past the intake valves and then into the combustion chamber. Now once the air as well as fuel would be combusted, then the exhaust gases would exit the combustion chamber past the exhaust valves, through the exhaust ports, and then to the exhaust manifold. The intake and exhaust valves would be situated inside the cylinder head. It would allow fresh fuel as well as air to enter, and then the combusted exhaust gasses to exit the chamber. Just keep in mind that they should be timed precisely when it comes to the opening as well as closing at the right times so that the car engine would keep on running smoothly. It would be achieved with a system of parts which is called as valve train.
• The same parts which would be utilized in the valve train would differ as per the engine layout, but can contain, in addition to the intake and exhaust valves, rocker arms or camshaft or two camshafts. It is the rocker arms which would push on the valves to open and close them. They in turn would be moved by the push rods or lifters which would respond to the camshaft which is situated in the block. There are some engines which would have the camshaft situated above the valves where it would be able to operate them directly. What parts would be present and then how exactly they would work would totally depend upon the configuration of your head as well as valve train.

Cylinder Head:

Step 1

The first and the foremost step would be to drain the engine oil. The drain plug should be removed from the engine oil pan and then all the oil should be drained into the plastic pan.

Step 2

Then the next step would be to drain the coolant. The drain petcock of your radiator should be unscrewed and then all of the coolant should be drained out of the cooling system.

Step 3

Then the next step would be to remove all the accessories. If there would be any accessories around the engine cylinder head, then they should be removed.

Step 4

After that the intake manifold should be removed. A ratchet or wrench should be utilized to remove the intake manifold from the engine cylinder head.

Step 5

Then the exhaust manifold should be removed. Carefully remove the exhaust manifold from the engine heads.

Step 6

After that the valve covers should also be removed. A ratchet and socket set should be utilized to remove the valve covers from the engine head.

Step 7

Then the timing belt or chain should be removed.

Step 8

If there is a rocker arm shaft equipped in your car engine head, then you will have to remove it.

Step 9

Then carefully remove the cylinder head. The engine head should be removed by carefully lifting it off of the block. There would be a requirement to utilize a shop rag and a pry bar so that you can gently dislodge the head from the block. Just be sure that you do not damage the mating surface of the cylinder head.

Step 10

Then the head gasket should be removed. A flathead screwdriver should be utilized to gently pry away the head gasket from the engine block.

Step 11

After that the new head gasket should be installed. Then it is the turn to install the new cylinder head. The new engine head should be placed on the engine block and just make sure that it is seated in a secure way.

Step 12

The mounting bolts should then be installed. A thin layer of engine oil should be applied on the threads of the head so that the mounting bolts can be blocked.

Step 13

The rocker arm shaft should then be installed. Now if the automobile would have a rocker arm shaft, then you should install it along with the rest of the valve train constituents.

Step 14

The new timing belt or chain should then be installed. The new timing belt or chain should now be reinstalled.

Step 15

The valve covers should then be installed. A ratchet set should be utilized to reinstall the valve covers.

Step 16

The exhaust manifold as well as intake manifold should then be reattached.

Step 17

If there are any accessories, then they should be reinstalled. Then refill the coolant. The radiator should be refilled with a 50/50 mixture of antifreeze coolant and water.

Step 18

The engine oil should then be refilled as per the recommendations of the car manufacturer.
