Today, Computer Aided Engineering (CAE) is standard in the up-front gasket development. As presented three years ago, it helps to reduce the development cycle and at the same time the development costs. With the success in using this approach, we received new requirements from the customer requesting for more and better details so that the project can be completed within the same time frame. The theoretical advancement and the drastic changes in the computer hardware technology along with lower costs aided in fine tuning our previously developed approach and adding new features. So we upgraded our specialized Proteus® software for the element study and extended it into the multi-layer 2D case. Further, more we detailed and improved the simplified 3D-model module as well as the whole bank 3D-model. A very important addition is the flow/thermal analysis to create the thermal map with our models.

Today, Computer Aided Engineering (CAE) is a feature that is essential in gasket development. The reasons are that we need to reduce the development cycle, and that we need simultaneously to reduce our costs. This paper and presentation will describe our general CAE approach, which is based on the Finite Element Analysis (FEA) and their modifications. We will describe our approach and how we use the results in the development of new MLS gaskets. Because this approach is based on the knowledge of parameters that exist and how they influence a gasket's function, we first of all will discuss the most important of these. Further we will explain the FEA utilization. We will also describe some special features of different software and subroutines (like “Proteus®”). Then, we will further describe how we obtain information about the beading process, the durability, the sealing gap oscillation, etc. Finally, we will give a short overview about some modifications compared to the classical FEA.

The trend in the diesel engine industry is toward longer service life and higher reliability. This trend is accompanied by increased power ratings, stringent emissions standards, and improved fuel efficiency. Consequently, the functional requirements of cylinder head gaskets are often beyond the performance capabilities of traditional gasket materials (nonasbestos paper, graphite, etc.). An engineering effort focused on the functional sealing requirements of current production and future diesel engines, resulted in the development of Edge Molded Metal Plate (EMMP) Cylinder Head Gaskets. This paper examines the design and material considerations and concludes with the primary reasons for selecting EMMP gaskets.

Gaskets using advanced gasket composites (AGC) have been developed for automotive applications which show considerable promise in improving gasket performance (sealing characteristics) at low clamping forces. AGC as a gasket material shows excellent performance under automotive environments. It compares well with a Kevlar fiber paper material. AGC gaskets for water outlet and water pump applications have performed better than the existing gaskets on fixtures and in field. This technology offers several other attractive features such as low scrap, recyclable material, flexibility in design, consistent quality, easily moldable features and messages, etc., some of which may be particularly advantageous to the aftermarket applications..
