@@marine-knowledge-basha welcome future CE.

@@makinistangmandaragattv5560 Thank you for your wishes sir

Thanks for your good compliment sir... This hydraulic tightening i had seen in MAN B&W ME (ELECTRONIC ENGINES).

Thanx for your query sir... Accumulation of sludge depends on hw speed and load the engine s running. Usually u can hv visual inspection on Accumulation. If you find abnormal sludge that may be due to * Drain line could b clogged. * Fuel injection is not proper * Fuel injecttor leaking. * improper tightening of fuel injectors. Hope this reply will satisfy your query

Thanks sir.. For sure vl do.. Pls giv me sme tme..

thanks for your good question sir.. * Adhesive wear is caused by loss of oil film and leads to piston and liner to have metal to metal contact that may reach to localised welding and leads to scuffing.. * Abrasive wear is caused mostly by cat fines which is contaminated in fuel oil. This leads to rubbing of Abrasive wear can be caused by hard asperities in the components rubbing against each other or by hard particles from contaminants such as catalyst fines (cat fines) from fuel oil. These hard particles embed themselves into the piston ring and/or liner surface and breach the oil film, thus abrading the surfaces and wearing them down in high speed. * Micro seizure indicates the beginning of wear and can be rectified by increasing the cylinder oil feed rate. I beleive this reply will satisfy your query,

@@marine-knowledge-basha ❤❤❤❤

Sorry for the inconvenience sir..vl correct it in near future... Thanks for your good advise..

It's average pressure is around 1 bar when aux blower is not running...

@@marine-knowledge-basha I see, I ask because I heard a story of some guy getting stuck in there and apparently he died from high pressures and overheating

@@mwbgaming28 sir in this case the guy must have been inside the chamber because of intentional or accidental closing of scavenge door without inspecting for any person inside.

@@marine-knowledge-basha he went in there without telling anyone and someone closed the door on him, the captain though he left the ship and was ditching work, so he started the engine and the ship departed on a trip that took a few days (they were going to a dry dock or something for major maintenance) and they found the guy dead in the air scavenging receiver Do you think it was temperature or pressure that ended up killing him? (Seeing as the combustion chambers are directly exposed, I would think it would be both)

U can order through maker... Its called elcometer..

@@marine-knowledge-basha And if the ship is using cermet coated piston rings, we can order that, right??

Pls go ahead vth ur query sir

thanx for your query Pravin.. Vl upload a vdo on it shortly

Just gv me a day vl upload soon.. It will b easier to understand if is shown in vdo... Kindly bare vth me

Hd uploaded it requested vdo. pls watch nd comment if there is any..

Sir.. H5 type piston rings come with al and ceremot coating.. This type of piston rings are used in latest ME engines. Hope this reply will satisfy your query

Sir the number depends on size of engine

Its a container ship sir,....

..

sure saab will do ....jrur karegha
