The device has been developed to solve a particular situation rising when testing piezo common rail injectors, as the piezo actuator must result lubricated before being energized. PiezoDevice 87.20.116 is the specific device to be used on an exhisting DIT31 test bench for diesel injectors. Piezo actuator control requires the addition of CRP module to the external unit TC38.Ĭonnection and test methods keeps unchanged contrary to the test of electromagnetic common rail injectors. The electromagnetic actuator control is delegated to the external unit TC38, which once synchronized with DIT31, generates the excitement command, via smartcards. The injector in the center has at least one of the nozzle holes with a reduced diameter by dirt or oxide while the nozzle holes of the injector on the right are expanded by wear. CRS3 peut être utilisé pour tester la pompe à rampe commune ,et également injecteur solenod(6pcs) et linjecteur piézo-électrique. On the left, the injector injects the correct amount. This parameter, together with the injection time, determines the amount of the injected fluid. On the left an injector that pulverizes exactly on time, on the right an injector that responds with a delay.įor each chatter, at constant pressure DIT31 calculates the difference between the level of pressure on opening and closing of the nozzle. Injection time is the time elapsed between the opening and closing of the nozzle. Opening delay is the time to translate the electrical command into a mechanical movement We offer a high-quality common rail injector reconditioning service and test, repair, recondition & supply common rail fuel injectors. The injector on the left has an acceptable quantity of return the other one on the right has an extra internal leakage. Known the acceptable leckage time, any lower value indicates a too high back leackage. With the injector pressurized, the pump is stopped and the pressure drops gradually, depending on the return. Piezoelectric actuator control requires the additional CRP module to the unit TC38.Īctivated the automatic triggering cycle, it is easy to find the minimum pressure which allows the chatter.Īctivated the automatic triggering cycle, it is easy to find the minimum pressure which allows the chatter pressure difference during the injection time the time interval between opening and closing of the nozzle (injection time). New protable Multifunction Diesel Common Rail Injector Tester DCRI188 Electromagnetic and piezo common rail injector tester. Automobiles & Motorcycles Car Repair Tools Diagnostic Tools Engine Analyzer. The most popular method to measure the flow of a common rail injector is to collect in a graduated glass the amount of liquid introduced during a known number of injections and compare this volume with the graduation of the container.Īn alternative able to provide higher resolution, is to split the flow in its two fundamental physical parameters: that is, type: Diesel electromagnetic and piezo injector tester by Mobile phone functions: comon injector test tools for magnetic and piezo injectors SKU: E0066A CRI808s Bluetooth version Competitive: Upagrade Version from CRI100,KW608,CRI800 Show All.
