| Effect | It is a sealed cylinder that forms a combustion space together with
the piston and withstands the action of high temperature and
pressure gas. The cylinder head is subjected to the mechanical load
caused by the air force and the tightening of the cylinder bolts,
as well as the high thermal load due to contact with high
temperature gas. In order to ensure a good seal of the cylinder,
the cylinder head can neither be damaged nor deformed. For this
reason, the cylinder head should have sufficient strength and
stiffness. The following are the design requirements of the
cylinder head: 1, the structure of the cylinder head is complex, the temperature field is seriously uneven, resulting in large thermal stress, which will cause cracks and overall deformation of the cylinder head; It has sufficient rigidity and strength, small working deformation, and ensures sealing; 2. Reasonable arrangement of combustion chamber, valve and airway to ensure the working performance of the engine; 3, the process is good, the temperature field is as uniform as possible, reduce thermal stress, avoid hot cracking phenomenon. |
| Working conditions and requirements | The cylinder head is subjected to the mechanical load caused by the air force and the fastening of the cylinder head bolts, as well as the high thermal load due to contact with high temperature gas. In order to ensure a good seal of the cylinder, the cylinder head can neither be damaged nor deformed. Therefore, the cylinder head should have sufficient strength and stiffness. In order to make the temperature distribution of the cylinder head as uniform as possible and avoid hot cracks between the inlet and exhaust valve seats, the cylinder head should be well cooled |
Cylinder head material
The cylinder head is generally cast by high-quality gray cast iron or alloy cast iron, and the gasoline engine for cars mostly uses aluminum alloy cylinder heads.
Cylinder head construction
The cylinder head is a box-shaped part with complex structure. It is processed with inlet and exhaust valve seat holes, valve guide holes, spark plug mounting holes (gasoline engines) or injector mounting holes (diesel engines). A water jacket, an inlet and exhaust passage and a combustion chamber or part of a combustion chamber are also cast in the cylinder head. If the camshaft is mounted on the cylinder head, the cylinder head is also machined with a CAM bearing hole or a CAM bearing seat and its lubricating oil passage.
The cylinder head of the water-cooled engine has three structural forms: integral, split and single. In a multi-cylinder engine, where all cylinders share a cylinder head, the cylinder head is called an integral cylinder head; If there is one cover for each two cylinders or one cover for each three cylinders, the cylinder head is a split cylinder head; If each cylinder has one head, it is a single cylinder head. All air-cooled engines have single cylinder heads.
