Modern 4 strokes actually run higher pressure now. MTU 8000 series at even 1500 bar injection!! Common rail have recirculation lines on 4 stroke too right. Confused how hydraulic oil cleans 2-stroke injectors, please explain.
1. Both 4 Stroke Fuel Injector & 2 Stroke Fuel valve has recirculation line. (In main engine we call it Fuel valve and not Fuel injector) 2. Opening pressure varries and can be adjusted as req. 3. Distribution holes and Position on Fuel Injectors & Fuel valves on cylinder head are corelated. You are doing a good job just read the manuals and compare them accordingly.
Thank you so much for this clarification.😊 All your points are Well noted.. Clarification of points is utmost important.👍Thanks for ur participation in this discussion. Much Appreciated..🙏
@Roshwin Vaz there is no recirculation line in 4stroke fuel injector..because we start and stop by using diesel..but in 2stroke engine during port stay only engine in off condition and that time we r doing preheating of injector to avoid vapor lock and carbon deposit over fuel injector and to avoid thermal shock then it is easy for us to start the engine..
Ane u r saying stupid thing like main engine it is fuel valve and aux Engine it is fuel injector..both r same only..in both we say it as fuel valve only
Great video. Only recirculation part of Auxilliary Engine is confusing as all the fuel exiting through the fuel pump might not be injected through the fuel injector because at the time of Starting and Stopping of the Engine, the situtation will be different, in many of the ship's in which I sailed, the Auxilliary Engine's were started directly on HFO.

Why we are using hydraulic oil to test fuel valve is it because of fuel test pressure or any other reason

For generator on my ship we used to start the engine on diesel then changeover to HFO for normal operation so will it have recirculation line ??
Check your Generator manual for that info
what is the difference between opening pressure and injection pressure of the injector?
Opening at which fuel injector gets opened.
Injection, pr at which fuel is being injected into the chamber.
Arree kitna simple tha ye , thankx for making it so easy to understand.👍
Welcome Abhishek, thanks for making this channel valuable..!
@@CLASS4ORALS we are lucky enough that u r doing so much of work for us. Really appreciated your efforts. Keep it bhai👍👍
Thanks alot. Its not me who put the effort. Its the Spirit of Seafarers that boosts me always to share max content.😊🙏
Great sir 🔥🔥
Thank you..😊👍
ARE you sure about recirculation part?
You may check with your manual..I might be wrong ..Corrections accepted..👍
Recirculation line exists
