connection nozzles DENSO
Turn off the fuel pipe of one of the injectors (I chose the far left) and fasten it in place of our Japanese nozzle so that it was convenient to collect and return line to the spray she did not particularly spattered.
To collect the "return line" I put a little faceted glass. Do not connect the electrical connector. It keeps a check to the check valve. From intact nozzle without electrical signals and pressurized fuel flow should not do. Of faulty almost immediately begins to flow. Spin the starter:
Nothing comes out of the return channel, then the check valve does its job.
Let's see how this will spray nozzle, by connecting it through a homemade extension cord to the connector.
The nozzle is connected, we turn the starter:
Starter turns, and do not spray nozzle. Maybe it lacks the pressure that is at the start of the engine CRDI developing, can talk to her too small. I do not know. However, no spraying, and spray tip was covered with oil. Oil may be too thick to be sprayed at a pressure. Then try to put the connectors on the two nozzles in the engine, so that the two cylinders helped to turn the starter motor. The speed of rotation is more-the fuel pressure will be higher. Let's see:
The nozzle was spraying, fingers felt as strongly fly trickles. So injector is working. In a glass of reverse channel dripped diesel fuel.
A nozzle does not need me now, I'm ready to change it to 8000 rubles. I have a number of the person from whom I take this injector, he still has two of these, but not shelled. I'm in St. Petersburg. Write in the comments or via the contact form.
Today (06/04/2013) went to the Bosch service on testing of the nozzle. Test plan in their particular model is not, therefore tested on a common plan for DENSO and there is no numerical parameters of the fuel, there is only "return pipe" at 1600 bar. Report:
