VICTOR REINZ has worldwide access to 27 engine test benchs and associated laboratories for analysis and static/ dynamic pre-testing through DANA Sealing Products and its four development centers in Germany, North America, and Japan. All activities are coordinated by the Competence Center R & D in Germany to ensure your testing incorporates the most advanced technology in the world.

rework of the injection mold (camber) or a modified gasket topography. Finally, the results are compared with the FEA calculations. In this way, we can ensure that our simulation models become more precise with every step. Leakage test The leakage test determines the sealing tightness of the overall system. In addition to the gasket, particular attention is given to other Sealing elements, such as injection nozzle Seals and the leadthroughs for electronic contacts. For this test, the cylinder head cover module is mounted on a perfectly flat metal plate. The sealing gap of the gasket is measured, and a defined internal pressure is applied to the cover module at room temperature. After a specified time, the leakage rate can be calculated from the difference between reference pressure and pressure loss, and the precise location of the leak is determined. According to the corresponding technical and customerspecific demands, this is the measure of the module’s sealing tightness.

Fuji test according to RPM 550 1) Sealing tightness measurements are the key to success for the validation of cylinder head cover modules. One of the most critical elements is the cylinder head cover gasket, which seals the cover module against the cylinder head. In the first step, pressure-sensitive Fuji film reveals the gasket’s pressure distribution on the cylinder head. For this test, the cylinder head cover is mounted on the original cylinder head using original Bolts and a precisely defined torque. If the pressure distribution is uneven, correction is possible with a suitable

First, pressure-sensitive Fuji film reveals the pressure distribution of the cylinder head cover gasket. The intensity of the color is a measure of the projected sealing tightness of the overall system of cylinder head, gasket, connecting elements, and cylinder head cover module.

Leakage test: Every cylinder head cover module is tested for sealing tightness. Apart from the gasket, other sealing elements such as injection nozzle seals and Spark plugs are examined.
