The new impulse test stand from Automotive Testing Expo Europe exhibitor Poppe + Potthoff is extremely compact. It enables validation of common rails, injection lines, injectors, pumps, and other metal and plastic components with up to 2,000 bar at a pulse frequency of 2Hz – 10Hz, depending on the pressure unit. It has a safety chamber with nitrogen flushing for safe testing in gasoline and an optional second chamber with a separate test circuit for simultaneous pressure-testing with oil.
During the development of the new system, the company’s experts used their extensive experience with diesel injection systems. Poppe + Potthoff tests these with up to 6,000 bar pulses at 1-30Hz.
Johannes Montag, head of sales at Poppe + Potthoff Maschinenbau, said, “There are particular challenges when testing metal and plastic components for direct injection of gasoline. The permanent pressure strength of the components needs to be tested considering varying bio-ethanol content in gasoline. Thereby, pressure cycling tests must take place under special precautions to safely prevent the development of an explosive mixture of petrol and air.”
Data acquisition and visualization is carried out in the National Instruments LabVIEW application. All test procedures and data are automatically stored on the system and can be exported into the network for further analysis.
