[Hindi]Working of Diesel engine and knocking phenomenon

[@dhruvkumar-st8it]

One of the well explained video i had ever seen keep it up sir

[@bikram971]

Thank You Amit Ji for this informative video about ' knocking of diesel engine'. Really appreciate it!

[@PRAFFULKUMARBME]

bohot sahi sir jee!!.. important concept clear kar diya aapne mera..thank you so much

[@decentone7185]

bht behatareen... umdah sb smjh m aagya

[@k.hemantkumar9609]

Very nice video sir....bht detail me bht asani k sath samjhaye hai aap..thanks sir

[@ansariadeel782]

Sir you are the best just salute you sir!!! 🙇🏽🙇🏽🙇🏽 thankyoou so much

[@_basu_6320]

Very Good Explanation Sir.....

[@razajamshid4132]

Great vedio very informative and easy to understand

[@aprozpatan5340]

sir plz tell me that why my swift dzair car releas knocking sound while iam going to keep in 1st gear after move and after 30 kmph speed sound was hide and how can i fix that

[@urmiladevi-bf2je]

Sir please more video upload for automobile related

Sir supplying compressed air is same as supplying heated air instead of normal air in the cylinder to shorten the ignition delay right ???

[@Dr.AmitMandal]

Supplying adiabatically compressed air will boost the performance and decrease the ignition delay , the use of supercharger in diesel engine does the same activity in diesel engine .

[@dibyajyotinayak2197]

Nice explanation of combustion phenomena.

[@ansarisarfraj1984]

From where piston get energy for suction & compression strokes?

[@Dr.AmitMandal]

By stored mechanical energy in flywheel during working stroke.

[@surajvishwakarma4911]

i have a doubt..during compression stroke piston TDC pahunchne k pehle crank kitne degree pe hota h jb fuel inject hota h ..

[@Dr.AmitMandal]

+Suraj Vishwakarma -if you want magnitude , you can find in google.

[@shubhamsrivastava2832]

very nice explanation sir

[@gurpreetshergill6001]

sir.. heat addition process in diesel engines occurs on constant pressure... then how can its pressure get increased...plz elaborate..

[@Dr.AmitMandal]

+gurprit singh that's in ideal diseel cycle only

[@borbanv]

good

[@vishalmane6602]

nice explanation sir plz...upload more videos...

[@suryakantsingh5691]

sir,there is any diffrence between knowking and detonation?

[@Dr.AmitMandal]

+mohit sahaniya strictly speaking , knocking is a indication of detonation .

[@Dr.AmitMandal]

mohit sahaniya

[@dsingh3750]

GOOD EXPLANATION SIR

[@conceptwallahesegatepsusss9249]

awesome explanation sir

[@milanmerja8616]

please upload more video

[@shahbazkusha4481]

Nice explanation

[@techissue7481]

it is to difficult to find you sir so befor uplode the video pls attachd your some sign or phots bcoz ur lecture is really great sir and this video very usefull for me thnk you for uplode this video ....all doubt cleard

[@Dr.AmitMandal]

+sufiya shaik thanks for compliments my profile pic is there ...

[@techissue7481]

no i mean provide video frount pictre so that we all can find you at just one look other wise we are start cheaking step by step all video and then we got you after cheaking 5 or 8 video so all i m trying to say that attached your pic in your video as frount pic...

[@gagankhurana4498]

NYC video bro too good and easy to understand

[@sachinjoshi3986]

This is really helpful... Thank you :)

[@sumansaha955]

Thanks for the nice lecture, Sir.. Please make more videos, It will be really helpful for us.

[@NARESH8575]

Thank you for this nice video...could you please explain more about Cetane number of fuel and Ignition delay. This is the only point which is not clear to me.Otherwise the explanation is superb.

[@Dr.AmitMandal]

+NARESH8575 you would have understood that lesser the ignition delay lesser the knocking tendency. Thus cetane number is an index which is analogous to the ignition delay of fuel . I.e. greater the cetane number ,smaller the chances the diesel engine to knock.

[@Dr.AmitMandal]

I mean more the cetane number of fuel is , lesser the ignition delay would be and lesser the knocking would be

[@ThecardoctorTCD]

Dear sir any other video related ic engine

[@shashwatraj3157]

very nice video sir

[@holydevil40]

Very good keep uploading more videos sir.

[@kundanjha2529]

great video

[@amritpoudel8960]

very awesome info

[@madhukesh_gaming_vlogging6300]

nice explanation sir loved your way of explaining...

[@mayankrajprajapat8542]

I liked your video because you made it like-able.

[@Flashflits-xb3ml]

thanks a lot sir..it's so helpful for me...again big thanks..

[@utkarsh2301]

Mandal sahab i turned fan to your knowledge on IC engine.

[@milanmerja8616]

nice video

[@SudhanshuSingh432]

very nice sir

9:10 thanks me later

[@ansariadeel782]

Thank you so much

[@vimalprajapati913]

thanks for discreption

[@mdqaisarraza5064]

nice sir..

[@bloodymechanic]

Nice lecture sir...

[@balajikumar9]

i dont understand hindi.... but i have a doubt.... i have read that autoignition temperature of petrol is higher than diesel, then why is SI engine is subjected to knocking at high temperature... why they cant be compressed to higher comp. ratio as CI engines

[@Dr.AmitMandal]

+balaji kumar same lecture is in english also take help from that....

[@arpitgupta1774]

I have a doubt, As we know the efficiency of all reversible cycles operating between same temperature limits is same, Then for same temperature limits why we get different efficiencies for different reversible cycle, as we know we get maximum efficiency in case of Carnot cycle, Basically, I am asking- Are Otto and diesel reversible? if yes, then why we get efficiency of such cycle less than carnot cycle, Thanks 🙂

[@Dr.AmitMandal]

Work is path function, isobaric , isothermal, isometric works have different magnitudes even ideally.

[@arpitgupta1774]

@@Dr.AmitMandal thank you sir, for answering me, But I still have the same doubt Are Otto and diesel cycles fully reversible ?

[@Dr.AmitMandal]

Otto and diesel cycles are theoretical, they are reversible.

[@brijeshchouhan6939]
