Quick-disconnect coupling with NFC technology helps manufacturer secure engine testing process
CEJN Products India

A global supplier of engines for marine and industrial applications was looking for a solution that could ensure that its engines are tested with the correct fuel quality. The key was to use near-field communication (NFC) technology with the CEJN Identification System in combination with 565 series couplings – a unique customer solution.

Eight different fuel qualities are used for different markets and, by running fuel tests of prototypes and calculating technical data, the engine manufacturer makes sure the requirements are reached. Fuel hoses could be connected incorrectly, and if the engine were tested with the incorrect fuel quality, this could lead to incorrect emission values that would be picked up during test evaluation, in effect making this test cycle corrupt and having to be re-run. Any re-run of testing is costly and can mean delays to engine testing projects.

At first, automated solutions seemed to be the way to go to ensure that the right fuel is tested with the right engine, but after careful benchmarking against other test devices, it became clear that engineers need to control the system manually. The development procedure was quick and, two months later, the first prototype was in place. Engineers said it was the software that took the longest time.

Initially, two sets of the solution were installed in the fuel cabinets to test hardware and software. The engine manufacturer ended up switching its couplings to CEJN 565 flat-face quick couplings with integrated CEJN Identification System (CiS). Each nipple is equipped with a tag with an individual ID. Once the coupling is connected to the nipple, a reader on the coupling reads the ID and the CiS device sends signals ensuring that the correct engine is connected to the correct fuel quality. If the wrong fuel type is connected, there is a clear indication on the screen and the test sequence cannot be initiated.

Now that the invention is installed in two of the engine manufacturer’s test cabinets, 11 more cabinets, which are in production, will be equipped with CEJN CiS.
