Large Diesel Engine CRiN injector (QSK, MTU, L ’Orange, etc.The working principle of these injector typologies is illustrated, and their hydraulic performance has been analysed and discussed on the basis of experimental data collected at a hydraulic test rig. Tester CRS300 Tester CRS300 is a comprehensive tester. CRIN 4.2 Heavy Commercial-Vehicle injectors A comprehensive comparison between solenoid and indirect acting piezoelectric injectors has been carried out.XPI, F2E, F2P, F2R Injectors pumps and more.Capable for all EU6 technologies such as VCC and NCC technology, iART, PCRS5,.CRi / CRiN / GDi injectors (All Brands and Types). Functions: The function of the CRI205 high pressure common rail injector tester is to drive common rail injectors and injector AHE function tests.6-12 minutes testing and coding* time for 4 injectors.Heavy-Duty CR pump (CPN5S2, CAT, Cummins etc.).Capable for all EU6 technologies with Sync Operation such as Denso HP5,īosch CP4-EU6, VDO EU6 technology and more.So you can see it's a little bit different, but as long as you know the theory, it'll help you diagnose it. So that goes around.Īnd then when it's released, we're still going to get another spike into the injector back into the line, when it closes. CR 1 PT Premium, Exact and fast CR injector and pump TESTING Performing complete and accurate test of multi-brand CR injectors and pump. Then the amperage drops off slightly, and then it comes down and then as it says, it modulates the amperage up and down to keep the inject open.Īs the amperage goes up and down, the voltage has to follow that as well. You can see that we have a little voltage spike right there, and at the same time the spike goes up, we also have the amperage going up. This would be powering up the fuel injector. So let me stop it on this second pattern here. And you can see here we have two different types of patterns displayed. We're going to go into the lab scope, which I already have set up running on this vehicle. You can test Piezo injectors for flow and spray and electronic operation on the ASNU machine but we also recommend testing the insulation and the condition o. So now that I've got all this information here, they don't actually have a test that we can test all three things. It says the best place to test that is either at the injector itself on these, they're sometimes hard to get to or there's a 16 pin connector on the left rear side of the engine above the engine oil filter housing. It contains a smart driver that actually monitors each side to see whether there's a problem that will throw a code for whatever the problem happens to be. If boost voltage is unavailable, the correct injector opening current might not be generated in the time required.The injector driver controls three transistors switches that apply the boost voltage to open the injector and then modulates the current to hold the injector open.A boosted voltage supply up to 65 volts is generated in the PCM and used to initially open the injector.Each injector is controlled by two circuits from the PCM.The gasoline direct fuel injector delivers fuel directly into the cylinder under high pressure.Now it's going to give us some information so we'll go into Component Information and it says how the system operates: We have the vehicle ID here so we're going to go into the Fuel Injection System and then we're going to go into the Fuel System, and then the Fuel Injector. Inside all the lab scope tools is the Guided Component Tests and that can give us a lot of information on how things work and where to hook up on these vehicles. We have got a lot of information on how those injectors work and it's actually hooked up to this Ford behind me and we can see how it looks on a lab scope and how the pattern is actually different than a standard fuel injector. I'm going to walk you through it on this tool right here. Used for testing the fuel return pressure for diagnosis of Piezo injector condition. They had had been using it on diesel vehicles for quite some time but it's kind of new on the gas side of things, so if you've never worked on a diesel you might not know it's a little bit different. This specialised tool is designed for testing the return flow pressure from common rail Piezo type injectors of Bosch, VDO / Siemens & Delphi,Denso engine system. It's a far more efficient way of injecting fuel into the engine. A lot of newer cars use gasoline direct injection.
