Founded in 1995, Mifeng Sealing Products Co.,Ltd. is a professional China cylinder head gasket manufacturer and designer specializing in a diverse range of fiberglass products, seal components and packing for automobiles, motorcycles, machineries and home electric appliances. With ISO9001: 2000 approval, we have a strong team of experienced designers and production technicians. Our products have gained the certificates of ISO/PAS17712 report, US ABS group report and US customs approval. We also provide OEM cylinder head gaskets with origin production of some famous brands such as B+S, NOK, TTO, VALQUA and DZ. Also as a sale, we produce various accessories made of NR, NBR, EPDM and etc.

The increase in stiffness between the cylinder head and the engine block, as well as a change in the tightening procedure for the cylinder head baits, are essential modifications required for the turbocharged Diesel engine. As already mentioned thread size was increased from 11 mm to 12 mm along with deck thickness. The tightening procedure was changed from torque controlled to angle controlled. This technique is applied to both the 4- and 5-cylinder turbocharged Diesel engines. Deflection measurements indicated that even under increased forces, deflections stayed well below the usual limits.
Extensive testing was done to optimize the cylinder head gasket in conjunction with the cylinder block modifications. The final design of the gasket is shown from top and bottom views in Figure 62. The proper combination in fiber, rubber and metal material had to be specifically selected. An essential feature of the gasket is the equalization of the pressure distribution, obtained by the micro structure of the non-adhering surface treatment and the high degree of resilience even in the case of reduced pre-loads. A viton element with metal support is added in the region of the oil pressure hole.

One of the most important parts of the cooling system is also the most invisible
A cylinder head gasket is required to effect a seal between the cylinder head and block of a gasoline or diesel engine. It is an integral component of the engine and is requires to perform many functions at the same time during engine operation.
The head gasket must maintain the seal around the combustion chamber at peak operating temperature and pressure. The gasket must seal against air, coolants, combustion and engine oil at their respective peak operating temperature and pressure.The materials used and design employed must be thermally and chemically resistant to the products of combustion and the various chemicals, coolants and oils used in the engine.
When assembled, the head gasket becomes an important part of the total structure of the engine. It supports the cylinder head along with its operating components. It must be able to withstand the dynamic and thermal forces that are transmitted from the head and block.The type of engine application will be the determining factor in cylinder head gasket design. With engines ranging in size from one cylinder gasoline fired engines up to twelve cylinder, turbocharged or supercharged high-compression diesels, the material and design of the gasket is paramount to it’s functional life span.
