The HDA measurement device enables a comprehensive analysis of an injector characteristics. So besides the injected mass also the injection rate shape is determined with a high sample rate and recorded.
With 6 free analog inputs, it´s possible to record the injection characteristics synchronized with just one device. By analog input of the injector energizing signals in the HDA electronics an extended timinganalysis of the injection cycle can be performed.
If additionally e.g. the rail pressure signal is supplied the interaction of the injection system and the complete system is visible. A multiplicity of curves and measuring values are stored in the result data for each recorded injection cycle, which are available for an extensive investigation of the injector.
