- Time to team up with the 3rd engineer and change the nozzles of the fuel injectors and let's see if the newbie can explain how they work!
This is for yanmar 4 stroke diesel engines, a maintance done every 2500 running hours!
Super chill music from chill people :

I just started as a marine and technical engineer (student). These demostrations of the main parts, helps a lot better, for fully understanding hos the engines are operating.
Thanks ❤
That's the idea Aria, marine engineering made easy to understand and to awaken curiosity.. Thank you for your support
Thank you very much
Thanks for the kind words bro!
You seem like a good guy and your videos are very clear and informative. They will help me for when i go to sea next month. Watching the fuel injector spray must have been satisfying after re-assembling and reaching 45mPa. Good luck for the future.
Hahaha I'm glad you think that about me Adam, to tell you the truth I think we in the engine room should just be without mask, just how we are love it or hate it because those type of people don't hide stuff.. Hiding stuff from the engine team is dangerous hahah. Anyway about the injectors yeah its satisfying however I should have mentioned that the pressure depends on the model of the aux. Engine! I went to a different vessel with YANMAR Aux. Engines but they were a bit smaller and of course opening pressure was less (32MPa)
I came across your videos recently, such an informative and well explained videos !!! Thanks for your Honest efforts behind these videos ..Hoping for more fruitful videos in future
That is very kind, I really love my job and it makes me happy to share these small parts of the life of a maritime engineer.
You are awesome buddy, please keep upload videos, this video helps me to clarify my doubts, thank you
Thank you my friend for sure.. I'll get back to regular uploads soon. Thank you for your kind words and I hope to showcase many more machines and devices
If you can please do a video about auxiliary engine lube oil supply, about how it getting supply from crankcase to every where especially how it getting at rockerarm now am on vacation and doing my coc exams in India so it may be helpful.
Thank you buddy! Now I feel capable of doing this job all by myself.
Haha practice makes perfect Cristi, even after doing the same thing time after time sometimes I learn something new 😂 especially when problems start occurring. However understanding the principal is key to solve them. Success mi amigo
Good job bro...!!!! The assembly process shown with 2 videos and the working principle shown by animation made it very helpful to grasp the entire concept. Now even a layman can do the job. Please make more videos you have got an excellent explanation skill.
Hahah it's a cool job I hope you enjoy it as much as I did, success and nothing else Najin, have great and safe adventures always
Thank you so much for this kind of video. It helps me a lot especially like me as engine cadet. Very informative!
You'll be an awesome officer dude keep on studying and growing! We'll become sharks in no time
Thanks for your informative videos..it helps a lot.. Keep it up.. Wish you all the best☺
I gain alot from your explanations buddy.keep it up👍
I'm glad to read that Ubong! Keep on rocking my friend
Nice videography... Enjoyed,🐝
I appreciate your comments Kartik, success and nothing else, warm greetings from this newbie
Awesome video, a nice crack when testing. And that is the biggest meanest bench vice I have ever seen. Very unlikely anyone will take that home in there luggage.
Hahaha thanks again brother and really? People would take the bench vice home from the ship, uff that is a key tool for so many maintenance, I couldn't have that on my conscious.
nice video more power to your channel
Thank you tapel! This is the month for new content thank God
Thanks mate
Clear explanation...👍👌❤️
It may be missing technical professionalism but I hope it's enough to wake up curiosity. Thank you!
Super buddy thank you so much 😍
Thank you Anish, for your support! Success and nothing else dude
thank you sm for this.
You're welcome dude, success and nothing else
Informative nice bro..
Thank you! Suceess and nothing else friend
U are a star mate
Just a curious and happy go lucky newbie, now trying to be a curious hardworking officer. Thank you my friend
Yesss
😁😁😁
I like
Thank you my friend
The injection pressure is actually 34.0 MPa. I also work on these engines.
Depends on the size of the engine.. I have also worked on the smaller one that have an opening pressure of 34MPa..their max load was about 700KW.. Those in the video where for engined of about 880KW..in any case I should have explained in the video it depends on the engine.
❤️
Thnx brother..
Thank you for the support amigo!

Brother can u explane main engine injectors
And it's parts .
@@gshyam2132 If in the future Im able to work on the M/E injectors as a responsibility Ill do it, however its usually the 2nd Engineers Job I just assist.
Hi your
Video such a great
And helpful for all New comers
Make more videos for
M/E please
Thanks Sir
Hahah I'm still pretty newbie for the main engine but maybe some basics! Hopefully when I become a shark I'll show some awesome maintance of the Main engine. Thanks for the support!
Thanks for this informative video! That's a very interesting USSR ribbon on your uniform, where did you get it from?
Thank you Maxim, and that patch I got it from my first 2nd engineer! An amazing guy with lots of knowledge.. He gave it to me saying that it was an old patch he used to have for his overalls in old ussr days.
I was also born in Moscow (but from foreign parents) so I have a small connection to Russia haha
I think the calibrating oil medium to be used for testing must be an hydraulic an oil depending on your suppliers brand rather than diesel oil. Just an observation but still keep it up. :)
I've heard this before and yeah however I don't know exactly why.. The manual does not state a reason also, if you know it please share my friend.
Small correction.. When I say matted surface when referring to the spacer and nozzle it's actually an error.. Matted means uneven and this is the exact opposite! This has very smooth surfaces which should be kept clean!
do you reuse spare nozzles ? even after 2500 hrs? is it possible to recondition spare nozzles( using a super fine grinding compound on the tip of the nozzle assembly? and grinding it on the inside on yanmar engines?
I have seen this done and it can work in emergency, however most times the nozzle cannot be saved and the problem will persist.
These are manual injectors right. Do ships even use electronic injectors?
Correct they are manual injectors because they are timed by a mechanical part - the camshaft which activates the fuel injection pump.
Also as you could see the spring is adjusted manually to open at a certain pressure..incorrect adjustment can cause premature opening or late opening
There are electronic injectors famous in MAN B&W ME series, check them out! No chain and camshaft.. All hydraulically operated!
why testing pressure is low comparing to main fuel injection system in marine main engine?
One should check the manual, a mistake I made is that I didnt specify the YANMAR model I was working on at that time, each injection pump on different engines have different working pressures, therefore the nozzles also have different opening pressures to correctly atomize.
can u say the pressure and tightening torque for yanmar deisel engine model 6LX ET 659 HP medium speed
Hahaha quite specific my friend.. For the best information please consult the maintenance manual for your specific engine.
a question this one have nozzle cooling pipe??
The nozzles are cooled by water in these generators
More more or overhauled diesel generator.
Yanmar N21? Or N18?
Sorry for the late reply, this video was very old and honestly I dont remember but the power was 800KW max.
How come you touch the nozzle with your finger because your finger content a acid
Everything is clean before installation
When i saw this video i threw my phone...ouch
I don't know what you mean dude? Why?
@@ShrimptoShark i mean been an idiot after watching your video LOL
Hahaha I think I know what you mean, many times I feel this way too.
