Modern systems of direct gasoline injection (G-DI, FSI, HPI, JTS), for proper testing of injectors used in these systems, require devices with high operating pressure. Magneti Marelli offers devices for testing and cleaning such injectors.
Device characteristics:
• Test all types of electromagnetic and piezo injectors (0-300 V / 0-35A)
• Operation of 1 or 4 injectors (GDU4R)
• Working pressure up to 300 or 550 bar
• Electronic measuring system
• Dynamic mass measurement for the GDU*R series (accuracy: 0.2%, repeatability: 0.05%)
• Static mass measurement for GD1R series (Resolution: 0.1mm3, accuracy: 0.6%)
• Protect the control board from damage
• Unique PIEZO stack regeneration function
• Internal cleaning of injectors - MACC (versions * / F)
• Free database update
• Operation in automatic mode (only in GD1R-E / 30 manual pressure regulator)
• Test time: 5-15 mins (GDU2R / GDU4R) and 7-8 mins (GD1R)
• Built-in 10 “(8” GD1R) tablet with Android
• Clearly presented test results with the possibility of printing
• Available adapter for power supply all types of injectors
