Precise functional tests on hydrogen-carrying components are necessary to ensure that a hydrogen engine is ready for series production. For this purpose, Berlin-based tech solution provider IAV has joined forces with Sonplas to build a prototype device for testing the injection quality of hydrogen injectors. The basis of the development is the IAV Cross, a technical system for hydraulic measurement and functional analysis of injection valves.
For years, IAV has been using the IAV Cross to investigate the injection rates and quantities of any injectors for gasoline, diesel and gaseous fuels. In a cooperation project with Sonplas, the system has now been adapted to hydrogen applications. Hydrogen will also become increasingly important as an energy carrier for engine combustion in the future because it does not release CO2.
“We can draw on a great deal of expertise in the injection of conventional fuels. For example, together with our partner IAV, we are further developing the IAV Cross injection rate measurement system for operation with H2 injectors,” says Werner Riederer, sales engineer at Sonplas GmbH, based in Straubing, Bavaria. “We see numerous synergies in the test processes and equipment for hydrogen-carrying components. This enabled us to develop our H2 test stand in a very short time.”
The IAV Cross measurement system consists of a hydraulic unit, the electronic measurement and control unit, and software developed by IAV. The hydrogen-capable prototype is now undergoing a test phase lasting several months in preparation for its market launch next year.
