Gasket Research and Design

Measure the dynamic pressures that occur in an around various parts of an engine gasket for improved design.

Evaluate Engine Gaskets with Pressure Distribution

An important factor in maximizing the efficiency of an engine is making sure the combustion opening is properly sealed through the entire combustion cycle. Decisions need to be made about the block and head structure, fasteners, lubricants, torque, torque sequence, and gasket design. The I-Scan^® system is a valuable research, development, and quality control tool for gasket, fastener and engine design, and for manufacturing engineers. I-Scan pressure mappping sensors can be inserted into and around the various engine gaskets, seals, and fasteners to measures the dynamic pressure distribution at these locations.

The system provides valuable pressure measurement data to assist designers and FEA modelers who make decisions about these components. I-Scan can also be used for tests such as validating engine assembly techniques and “motoring” the engine to characterize the seal pressure changes that occur due to vibration, cylinder pressurization and torque. Tekscan’s patented, thin-film sensors are available in different pressure ranges, are reusable, and provide accurate pressure readings. With the help of our highly qualified sales and engineering support team, each system is configured to meet your specific needs.
