What Is the Cylinder Head
The shape of the cylinder head is generally hexahedron and is a component of the combustion chamber.
The shape of the combustion chamber has a great influence on the work of the engine. Due to the different combustion modes of gasoline engines and diesel engines, the parts of afr heads that make up the combustion chamber are quite different.
Main Components of Car Cylinder Head
- Head gasket
- Intake and exhaust ports
- Head valves
- Head combustion chamber
- Spark plugs
- Fuel injectors
- Head camshaft
- Additional cylinder head parts
What Does Automobile Cylinder Head Do
- Seal the upper part of the cylinder and form a combustion chamber together with the top of the piston and the cylinder wall.
- Engine head carries the parts of the valve mechanism and has channels for intake and exhaust.
- Press the cylinder in the correct position of cylinder block to make the piston run normally.
Symptoms of Bad Cylinder Head
- The engine power is not enough, and it is difficult to increase the speed.
- The cylinder has abnormal sound and does not work.
- The radiator is constantly short of water and the radiator is filled with air bubbles, or there are oil beads on the surface of the cooling water.
- Pull out the oil dipstick to see the oil, the oil is milky white.
- The cylinder head is deformed or cracked. This will lead to poor sealing effect, air leakage and oil leakage.
- White smoke is emitted from the exhaust pipe. And there is drainage in serious cases.

The cylinder head in car engine is mounted on the top of the cylinder block. It is often in contact with high temperature and high pressure gas, so it bears a large thermal and mechanical load.
1. The material quality of the cylinder head is not up to standard.
2. Excessive engine temperature or rapid cooling.
3. Lengthening or loosening of cylinder head bolts and nuts.
4. The installation process does not meet the technical requirements, and Unevenly tighten the cylinder head nuts.
5. Deformation of the interface between cylinder head and engine block.
6. Excessive carbon deposits on the cylinder head.
Engine cylinder heads are generally made of aluminum alloy and cast iron.
1. For Light duty gasoline engines, sbc heads are mostly made of aluminum alloys. The thermal conductivity of this materia is good, which is beneficial to increase the compression ratio. And the weight is also lighter, which can reduce the weight of the whole vehicle.
2. For heavy duty diesel engines, bbc cylinder heads are mostly made of cast iron. The rigidity of cast iron material is greater than that of aluminum alloy. Diesel heads are not easy to deform, but more compressive and good wear resistance.
