The test bench is designed for the entire analysis of important parameters of GDI-fuel
injectors. Explosion protected components enable the operation with n-heptane
as test fluid. The bench provides following test functions: Dynamic test, static flow test,
measurement of opening and closing times, injector spray characteristic.
