We explain how to ensure that the engine cylinder head sealing quality

Replacing the engine cylinder head gasket is a great difficulty of the work. For many Repairer of skill to do this work because many times the same as nightmares. If a first time in a car to replace the cylinder head gasket, did not do well in accordance with the technical requirements, then this car will certainly return to this Repairer requires repair at some point. If you do not use the correct cylinder gasket, do not follow the correct method of operation or does not make the right checks, the effect of your seal also certainly not ideal. Gasoline engine cylinder head gasket must seal the combustion chamber pressure in l000psi (1psi = 6.89kPa) above, the turbo diesel engine combustion chamber pressure sealed 7200psi or more. Also, the cylinder head gasket must be able to withstand more than 2,000. F temperatures. In this harsh environment of high temperature and pressure of work, even if there is a slight cylinder head sealing defects, it can lead to the replacement of the engine cylinder head gasket failure to work. Bi-metallic materials of the engine cylinder block and cylinder head is a compound made from different metals, and his appearance and the replacement of the engine cylinder head gasket of the work has become more complex. Most now use dual engine includes a metal material with a cast iron cylinder block and an aluminum cylinder head. Due to the different thermal expansion coefficients of metals and alloys and the shrinkage is different, so the bi-metallic materials to design a successful engine cylinder head gasket, has become a challenging technique many gasket manufacturers face problem.
