You must know the function of the car cylinder head because it is an important main component. The cylinder head is an engine-forming component that is mounted on the engine block cylinder.
Generally fastened with special bolts and made of aluminum alloy which has a mixture of other materials.
The cylinder head must be strong and can withstand high temperatures and pressures. The reason is, in the cylinder head there is a combustion chamber where the combustion process takes place which produces engine power.
Understand the Functions of Car Cylinder Heads and Its Components
The cylinder head is usually located in the cylinder block. Available in two materials to make the cylinder head, namely a combination of aluminum and cast iron.
With its presence, it provides a function that is quite maximum and important. Here’s the full function.

As a Valve Mechanism Fittings
The function of the first car cylinder head was as a complete valve mechanism. The valve mechanism is a mechanism that regulates when the valve opens or closes (intake and exhaust valves).
Therefore, it must be adapted to the performance of a 4 stroke engine. Such as combustion (combustion), suction (intake), compression (compression), and exhaust steps (exhaust).
The valve mechanism components vary, depending on the cylinder head model you are using.
Like the valve mechanism of the Over Head Valve (OHV) model, it will be different from the Double Overhead Cam (DOHC) valve. Likewise Over Head Cam (OHC).
Spark Plug Installation Tempat
Another function as a place to install spark plugs. This is at the same time to ignite the fire in the combustion chamber. So that the combustion process occurs and produces engine power. Spark plugs are mounted on this cylinder head.

Place of Combustion Engine
The function of the car’s cylinder head is where the engine combustion occurs. In the cylinder head there is a combustion chamber that has the function of burning and detonating a mixture of air and fuel. In this way the engine generates power.
In general, the shape of the combustion chamber on the cylinder head really depends on the model and type of engine you are using.
There are 3 forms of combustion chamber, namely pentroof (isosceles triangle), wedge model (right triangle), and hemispheric (parabola).
Where Lubricating Oil Works
One of the functions of a car cylinder head is a place for lubricating oil to circulate. There are several channels to channel oil from the oil pump, according to their performance to lubricate several components of the valve mechanism on the cylinder head.
The oil flow is connected to the main gallery oil which is located in the engine block cylinder. Various valve components are oil lubricated and in good working order.
The friction process will be smaller so that the valve mechanism is more durable and wear-resistant.

Where Cooling Water Circulates
The function of the car’s cylinder head is where the cooling water circulates. If the engine is hot for a long time, it will cause overheating.
The reason is the engine temperature rises due to the combustion process. The cylinder head has a place to circulate the cooling water. This circulation passes through the water jacket space inside the cylinder head.
The water circulation is connected to the water jacket in the cylinder block and plays a role in regulating the engine temperature. So that the combustion chamber is in accordance with the standard.
Intake and Exhaust Line
Another function is where the intake and exhaust flow. The meaning of the intake flow is the inflow of air into the combustion chamber which is regulated by the intake valve.
Meanwhile, the exhaust flow is the exhaust flow of smoke resulting from the rest of the combustion process from the combustion chamber which the exhaust valve regulates.
With the function of the two valves of the car’s cylinder head, the engine can carry out the work process so as to produce power to drive the vehicle.
Parts of a Cylinder Head
Some parts or components of the cylinder head as follows. First, the Spark Plug or spark plug as a producer of sparks for combustion. Second, Oil Seal as a seal of oil so as not to enter the combustion chamber.
Third, Adjusting or Rocker Arm as a valve gap adjuster. Fourth, Valve Seat as a valve seat.
Fifth, Valve Guide as a place to attach the valve to deliver the movement of the valve up and down.
Sixth, Valve Keepers as a lock between each valve with a spring. Seventh, Water Jacket for radiator cooling water lines to cool the engine.
Eighth, gaskets for intermediate bulkheads between the cylinder head and the cylinder block so that there is no leakage.
Ninth, Combustion Chamber for the combustion of fuel that enters through the intake.
In addition, it also includes a Valve Lifter, Intake Manifold, Exhaust Manifold, Oil Feed, Coolant Feed, and Head Cylinder Cover. The function of the cylinder head of the car is important you know. (R10/HR-Online/Editor-Eva)
