ABSTRACT
Gaskets for the internal combustion engine appear simple but in reality are highly engineered products. A gasket design is selected for use only after extensive functional testieg. Engine dynamometer testing, usually at overrated power outputs and thermal shock conditions, along with long-term field testing, are almost always conducted before the gaskets are adopted for use. Prior to the engine manufacturer's expending the costs involved in this testing, the gasket manufacturer must show that engineering analysis and testing support the expenditure.
