Optimizing today’s combustion engines involves extensive test bench measurements. The engine is measured in a steady state, i.e. at a constant operating point, as well as dynamically, i.e. with operating points changing.

It is necessary in all measurements to ensure that the engine runs within its operating limits, i.e. not violating any of them. These limits may be emissions, maximum cylinder pressure or knocking limit.

We perform these measurements automatically using ORION, a test-bench automation system we have developed. With the capability of parameterizing test processes, this allows us to produce complicated automation sequences for the engine test bench.

ORION controls the test bench in line with the measurement plans that are generated, for example, with a DoE tool like EasyDoE Toolsuite. Automating the test bench with ORION cuts measuring time while also enhancing the quality of measurement and documentation.
