| The automobile sealing material is mostly applied to three assembly units for engine, gear-box and axle. In addition, the engine sealing gasket has the strictest operating condition. The performance specification applied for automobile sealing technology is treated as the gross engine performance specification. The engine sealing technology will affect the reliability, security and environmental ability for engine.The engine is the heart of automobile. The engine property is the critical specification of automobile. The performance level of engine depends on the high efficiency operation with several cycle systems. And the sealing technology property is the most basic testing specification. Sealing technology involves many aspects including material component, construction design and manufacturing technology, etc. It will not only deal with single aspect, but also consider the design according to the requirement of sealing surface status and engine situation.To handle the whole engine sealing technology well, the primary situation of engine sealing parts has to be learned. It includes bolt torque, distribution of bolt holes, application temperature, sealing media and the distribution of sealing surface pressure, etc. After all aspects to be understood, the sealing material and process technology can be confirmed.This thesis researches and develops the sealing gasket with high performance for modern automobile engine by using the construction characteristic and environment requirement of 6DL engine developed by FAW group at present. The research involves metal frame and nylon net composite sealing gasket. This thesis systematically describes about sealing condition, sealing material, sealing construction, formula research, material test, product inspection, technical condition confirmation, bench run testing, road test and patent application declaration in details.
