I am in great confusion now . You are saying VIT means fuel pump plunger helix has different profile Super VIT means different rack which moves barrel up and down. One Anonymous video on Utube says. Supee VIT means electronic VIT. What is right ?
Sir VIT means simple VIT as in old fuel pps where the advancing is fixed for a perticular load ( dependant on fuel rack )and keeps changing as load goes up, but the amount of advancement can not be changed, that means how poor the fuel quality may be this system will only this amount of extra timing no matter by how much extent the combustion is completed, but in newrer models even to provide the extra time for poor fuels it has been designed to give not a fixed but a flexible advancement for different fuels with diff qualities some get 1 deg someget ,2 deg and 3 deg and so it is not constant for a perticular load that in super VIT.
Is there anything that you have not understood after watching this video??...Because i am making these ppt self explanatory to save time in explanation.
Poor atomization by the fuel nozzles, scavenging air pressure drops and reduction in compression pressure will affect combustion efficiency and Pmax will be reduced. This may lead to increased carbon deposits. Turbocharger efficiency is affected by increased deposits and carbonization, resulting in a further reduction of scavenge air flow. Un-burnt fuel residues which clogs and gums piston rings, which causes a further drop in sealing efficiency and hot combustion gases blow past the poorly-sealing piston rings further reducing Pmax.
PLEASE DONT FOLLOW THIS....this is wrong..VIT is not controlling the helix plunger.the helix plunger and rack is there there to give fuel as per fuel rack controlled by governer.The vit is controlling the beginning of injection by adjusting the barrel in fuel pump with the help of a rack arrangement.The super vit is when this controlling action is by an electronic device which also consider the scavenge pressure..what's explained in this video is not correct....
My friend I have made this PPT after doing bit research...but if u feel this is wrong then u can do ur own research...n do read ME engine manual n let me know after that if you could find something called super VIT for these electronic engines...u can send me the source n I will make corrections...👍
buddy u have confused urself. he is right in his video. u can go through video from RMES channel where the chief engg explains clearly what is vit and super vit. i think u saw electronic title in e learning and came to conclusion.
This is correct In vit there is an cut in the helix only no vit rack this is old system. In super vit there is separate vit rack and its controlled by pneumatic cylinder and signal from the governor. Adjustable breakpoint @the youtube guy pls watch this video properly and also read the book.
Friend u can download this app for PPTs and Videos related to MEO Exams: play.google.com/store/apps/details?id=com.meoexams.meoexams
Thank you very much sir... cleared my all doubts regarding vit and super vit.🙏
Feels good to hear that...😊... keep watching n comment down all ur doubt so that I can try to clear them in my upcoming videos.... thanks.
You are a very knowledgeable engineer. I truly appreciate your videos, Thank you!
Don't we study this ourself... We wanted to explain not news reading
Totally a bullshit video. If I understand by reading why have I come here to see explanation video?
Super vit could be explained in more detail as vit is explained along with difference between super vit and vit
I am in great confusion now .
You are saying VIT means fuel pump plunger helix has different profile
Super VIT means different rack which moves barrel up and down.
One Anonymous video on Utube says.
Supee VIT means electronic VIT.
What is right ?
My friend u can read on internet if u have doubt...but m sure about what I have presented..

Good effort sir..but u need focus on explanation because u just reading the notes.
Is there anything that you have not understood after watching this video??...Because i am making these ppt self explanatory to save time in explanation.
Can u pls post the this study material link in the description... It will be helpful for us
And yea thank you very much for the video 👍😇
I have not uploaded this anywhere, so I don't have any link to share.
And thank for asking me to make this video.
@@meoexams can you provide the file by the Google Drive link.... 🙏😇
Could you please explain why engines lose too much combustion pressure at low loads.
Poor atomization by the fuel nozzles, scavenging air pressure drops and reduction in compression pressure will affect combustion
efficiency and Pmax will be reduced. This may lead to increased carbon deposits. Turbocharger efficiency is affected by increased
deposits and carbonization, resulting in a further
reduction of scavenge air flow. Un-burnt fuel residues which clogs and gums piston rings, which causes a further drop in sealing efficiency and hot combustion gases blow past the poorly-sealing piston rings further reducing Pmax.
Okay understood thanks a lot
ThAnk you sir for the video🙏
U r welcome 😊
Nice explaination
Bhai just reading that , please explain so that other can understand In better way
Can u please provide the app on iOS please
Sorry my friend but till now I have not developed this app for iOS...but if u want u can read this material on website www.meoexams.com
goood reader.
Your video is good ... But stop maing that noise from mouth while speaking it's very irritating
Please work on your teaching skills dude. Just simply reading the paragraphs.
Kya likha hai kya padh raha hai...video toh thik se banao
Will try my friend...

N even MC engine monitors scavenge pressure...

@the youtube guy pls watch this video properly and also read the book.
