Basics of Fuel combustion in Diesel Engine-Part 1 |Ramesh Subramanian|RMETC Videos

This video will take you through the Basics of Fuel Combustion in Diesel Engines.It will deal with #Selfignitiontemperature,#Ignitionlag, Necessity of #VIT etc etc. It will form the foundation to understand the topics like difference between VIT and Super VIT and also appreciate the algorith of Combustion of ME Electronic Engines to b edeat with in future videos. Min Engine RPM ,Need to advance and Retard and Why Aux Engines dont have VIT??

THE BEST GUIDANCE ANYONE CAN GET FROM KZbin FOR MEO EXAMS.. I HAVE SUGGESTED THIS CHANNEL TO MANY OF MY FRIENDS APPEARING FOR CLASS 4 MEO AND IT IS NOW BECOMING A PART OF OUR MANDATORY STUDY MATERIAL BEFORE EXAMS .. KEEP UP THE GOOD WORK SIR .. HOPING TO SEE MANY MORE OF THESE AWESOME VIDEOS

Have been banging my head to understand this concept. Nowhere it is emphasized about the relationship between rpm and self ignition temperature and the minimum rpm to start the engine, which is considered as a reference to understand the need for ignition advance. Your 14 minute video helped me to end my misery of two days. Thank you sir.🔥🔥🔥

[@rmetcvideos]

Hold on..yr delight is a bit temporary..wait for part 2 which will come shortly..where we will be contradicting this very thing bcoz we will deal with the real stuff...what we have done in part 1 is the theorey..with lot of factors not considered for the sake of simplicity

[@vishnumohan2300]

Very informative. Thank you sir ✌🤝

[@shakilmahmud6179]

Excellent video sir..interesting and informative.

[@tanmay5492]

i wish every institute taught the way u teach. thank you sir for making things simmpler.

[@ravindraudakumbura4219]

Very good explain sir. Keep it up.

[@vaibhavnayak626]

Best explained!!

[@PramodKumarSahu]

I love the way you teach

[@Alphaplayersyt]

Sir..superb are your ways of explanation..i can go through all of your videos what ever duration it is..

[@krishnakumarr256]

AMMAZING EXPLANATION

[@vikrammgokhale]

Interesting questions, Ramesh 👌

[@bhuvanayyanar6524]

Im waiting for this one sir!!

[@ashusingh-jc2ns]

Great sir

[@amaranand2871]

excellent sir

[@sanatanibengal9210]

Very nice

[@bhuvanayyanar6524]

Waiting for part 2 sir!

[@biswajitguha7633]

Sir all your lectures are gem..🙏🙏

[@rmetcvideos]

Thanks a ton

[@aravinthraj3341]

All of your videos are very clear and informative. Happy to see your videos are being shared in studying groups and Chief engineers also recommend to watch your videos 😊 keep your good work towards younger engineers 🙏

[@rmetcvideos]

Thats nice to hear. Knowledge grows by sharing... :-)

[@PramodKumarSahu]

Need more videos. Sir ❤️

[@NeerajKumar-yd9qh]

Sir, your explanation was very informative. I would appreciate it if you could make a video about turbocharger surging.

[@najinkunnath6009]

🔥🔥🔥

[@sagarchoubey9157]

sir please make a full series on this topic

[@thanigaiprabhuravi4196]

Sir can we conclude ignition delay time varies with respect to rpm.. or ignition delay is inversely proportional to rpm. Ignition delay reduces rpm increases. To tackle this ignition delay we are using vit

[@campincar449]

What software you are using sir,, to make animation?

[@tejindersingh6149]

Sir please make video on propeller curve / load diagram

[@manmadharao8905]

Sir why fuel is not burning once injected even though self ignition temperature attained?

[@RajeshKumar-mt3pg]

Sir what is the meaning of 90 degree out of phase in draw card......what is meaning òf it......pls sir

[@akamalesh8512]

Sir does the time it takes for the fuel to ignite after attaining the self ingnition temperature is same at all rpms

[@rmetcvideos]

No...I am elaborating the details in part 2 along with VIT and Super VIT..this video is only for basic introduction of concept

[@jacobjoseph7460]

Sir, at the end of the video, you are saying at low loads engine tends to become inefficient, if we don't advance fuel injection. But sir at low load means, low rpm so we need to retard injection for the combustion to be efficient, don't we?

[@vigneshchandrasekar6197]

Good day sir. I have an two doubts What is the difference between main engine combustion and boiler burner combustion 2. Is there any Sox and nox limitations for boiler. If yes? What is the value sir? If no then why no Sox and nox limitations.

[@rmetcvideos]

I am not very thorough with this topic. Out of touch. But i guess the basic difference is in Engines..There is a peak pressure which is very high and hence NOX is the issue. But In boiler there is no issue of Nox. But SOX is beleive might be common..

[@muhammadjunayetnoor1126]

Sir, there is a major confusion regarding the minimum ideal firing speed which could be achieved using various means. Initially i was used to the concept that this firing speed was in fact needed to raise the temperature of the combustion air suffient enough to self ignite the fuel. But here you said that this speed is needed so that the combustion does not take place too early and stall the engine. The right and left side of my brain are now at war over this issue. Please sir stop this war.

[@rmetcvideos]

Ha ha..both are right..I also said that the S I temp depends upon the scavenge press and the time available for cooling water to cool the air...which means a good rpm is required..:-)

[@nishantsingh7773]

Sir, can you please make video for making punch mark for setting dial guage on the crankweb where it is not visible.

[@rmetcvideos]

.. a very difficult task,,since I amm not sailing now and have no access ..

[@AmandeepSingh-bj3ns]

For making punch mark the distance is d/2 opposite side of crank pin where d is diameter of journal. Distance to be measured from centreline of crankshaft

[@karanrajani3940]

When is 2nd part coming very much required

[@rmetcvideos]

Getting ready

[@olivertwist6855]

Sir, if load on engine increases, RPM will increase or decrease?

[@rmetcvideos]

Load is the power..If currents / winds are strong then the LOad may be high but RPM is same....If you increase RPM then ofcourse you are also increasing the load...

[@mec6953]

sir, pls teach us what is peak pressure

[@rmetcvideos]

Max Value of Pressure is Peak Pressure
