Why do we need cylinder heads?

To ensure good sealing of the cylinder, the cylinder head must not be damaged or deformed. For this purpose, the cylinder head should have sufficient strength and rigidity.

What to pay attention to when using cylinder heads?

1, the engine overheating.

The engine cooling system is not working properly, the oil supply time is too late, long-term overload work and so on will cause the engine to overheat, especially in the cylinder head of the intake and exhaust valve seat mouth and the swirl chamber channel between the outlet The part of the temperature is higher due to the role of high temperature, so that the cylinder gasket loses the original elasticity and becomes brittle, and eventually burned.

2, the quality of the cylinder seal itself is not qualified.

Uneven thickness, mouth volume is not flat, elasticity is not enough, the material is not good, the surface is not flat and so on, or the disassembly of the cylinder cushion is not careful to cause damage, which tend to cause this fire damage to the cylinder lining.

What are the most common defects of the cylinder head and its precautions?

1, cylinder head bolts, nuts of the extension or loose.

Due to the extrusion deformation of the cylinder head and engine body joint surface, compression deformation of the cylinder gasket, high-pressure gas pressure on the cylinder head bolts, nuts caused by accidental overload, the cylinder head bolts screwed into the depth, the microscopic unevenness of the thread surface is not sufficiently flattened, and caused by excessive torque caused by the shrink neck of the bolt and so on.

May cause cylinder head bolt nut elongation or loosening, resulting in pressure on the cylinder head and engine case and uneven pressure everywhere, resulting in high temperature and high gas pressure due to the local pressure of the smaller parts and burn the cylinder gasket.

2, the cylinder head and engine body common surface deformation.

When deformed, the two joint surfaces can not ensure that the cylinder gasket is pressed evenly, resulting in air leakage, which leads to cylinder gasket fire, which is also caused by the main reason for cylinder gasket fire.

Another function of the cylinder head cover is to act as an oil filler neck. This structure can be as simple as a hole into which the oil filler cap can be screwed; can also be a more complex oil filler pipe.

The cylinder head cover can also be used as a sensor mount, including camshaft position and camshaft timing sensors. Whether these sensors are included depends, of course, on the complexity of the engine.

The cylinder head seals the cylinder and, together with the piston crown and cylinder wall, forms the combustion chamber. It also carries the components of the air distribution mechanism, and the cylinder head has intake and exhaust ports for intake and exhaust air.
