Hello Young man, i saw your nice reply to my comment on sea suction strainer cleaning video. Now about regarding testing of fuel injector. My first ship named M.T. Jag Prakash a product tanker, an indian ship. 12,000 BHP, RND Sulzur main engine. Usually 3 rd engineer does main engine jobs. Fuel injector also called fuel valve those days will be removed from the cylinder head after safety procedures . Once after cleaning the pocket, and other checks an already overhauled injector will be fitted. Normally we use overhead crane for lifting. Those days there was no testing machine like you showed. But we use a pressure gauge range 0- 500 bar. Testing equipment was a small open tank with provision to fix the injector in place safely. A small oil container with d.o . connection to connect the injector, a pressure gauge, also a hydraulic hand pump for pressurising the valve is provided. Injector opening range i remember from 220- 260 bar. After venting we increase the pressure slowly. We check for the opening with a squeaking sound and spray. We also check for dribble /leak. We put a tissue paper below the valve for anydrops. Warning given by the senior engineer, no one should put a hand below the valve while testing, it will puncture the hand. Also when we overhaul the valve we check and clean nozzle cooling space. The test stand got a adapter for testing Auxiliary engine injectors. Learnt some thing new from you. By the way you are from which country. If possible your name also. My name is there on the comment. I am from lndia.

Hi Chief! Yet again, great to receive a comment from you, thank you. Thank you for sharing your experience, it's nice to know about how different things were back when you were a junior engineer. I am working as a 2nd Engineer right now and this job is still usually done by 3rd Engineer, but due to reduced man power (only CE, 2E & 3E as watch keeping engineers on board), depending on ship, injectors are also prepared and tested by 2/E. It's amazing to know how much of the procedures, details and parameters you remember even after so many years away from sea, even the testing injection pressure. Yes, as the engine generation advanced and technology improved, so did the Pmax and also the injection pressure. These days the injection pressure is around 370-380 Bar. Chief, my name is Rahul, I am Indian. I am glad this video brought back fond memories of your younger sailor days. Once a sailor, always a sailor 👍 Please do subscribe to my KZbin channel

I have one query about venting nrv test at 160 bar how the presaure ia dropping its because the sliding valve is getting slide fown and recirculating oil is leading to pressure drop ??

[@RoamerRealm]

Hi Mithun! Really sorry, this comment slipped my mind. Yours is a Great question, it got me thinking. During testing, I have always been so focused on seeing the the pump cut out around 160 Bar that I never really thought what’s causing the sudden pressure drop or how. However, the most likely reason for the pressure to drop is due to the recirculation. I have decided to make a video about the overhaul of the NRV especially for you. Hope that will help you understand the topic better. Thanks once again for the question and do subscribe to my KZbin channel 👍

[@saviodias8136]

I liked your video, can you clarify my doubt, i am a second eng, some fuel testing pump, on slide type fuel valve , say not to carry an atomization test as this will damage the slide valve and atomiser, when you test on the test bed it only spray but no atomization., can you guide me , to clarify my doubt, last ship i had the same testing machine like the one on the video, so i could perform an atomization test at 340 bar, can you clarify my doubt.

[@RoamerRealm]

Thanks a lot for appreciating the video. About your question: please tell me the make/model of the engine and the type of fuel system onboard (classic, electronic etc. Do subscribe to my KZbin channel 👍

[@rajatsinghgautam000]

It is a great video explaining the process. But sometime back I had a chat with technicians from MAN who explained me the same testing process but a bit differently from what you are doing. The discrepancies lie in the opening pressure test and the NRV test. I would like to discuss it with you someday so as to get a better insight on the same.

[@RoamerRealm]

Thanks Rajat for the feedback! Sure, hit me a DM on Instagram and we can discuss. Over the past decade I have interacted with various service engine and technicians, so, it’s always interesting to know what they have to add. Do subscribe to my KZbin channel! 👍

“RoamerRealm” - it’s the same name as KZbin. I also mention it in video description and during the video so I, unknowing, thought you would have already seen it and I didn’t want to spam

You put sulzer fuel vv pic and explain about b&w

[@RoamerRealm]

Hi Mumtaz! I have specified at the beginning of the video that it’s a MAN B&W fuel injector. The title of the video is for a “fuel injector” and the explanation is indeed that of a fuel injector. I am working on the video for a sulzer injector but in the interim, I don’t have any images with MAN injector to use as a thumbnail. I think the principal and operations of the equipment is more important. Let me know if you have any other questions and do subscribe to my KZbin channel 👍
