The size of inlet valves should be larger than exhaust valves to insure large volumetric efficiency to allow more air the cylinder that brings out more power and helps the scavenging process during valve overlap
Diesel is difficult to ignite because fuel mixture is not homogenous as that of petrol. Diesel has more fuel contaminants such as water and dirt. Hence Petrol burn at rapid speed than diesel. Autoignition temp is min temp at which fuel starts burning process. Though ignition point is low in diesel but burning process is slow due to non-homogeneous mixture. Hope u get it.

Q. no11 has answer efficiency increases
Bcz density of air increases due the decrease in temperature which results increase in efficiency
Yes
Good question buddy i watched the whole vedio 👍
thanks vai....these are important questions which boosted me...
Gud one
The size of inlet valve is larger than exhaust valve,tq
Yes. Right i mention in description of video.
NICE
Question no. 39 diesel is more difficult to ignite. But it's ignition point is 210 degree Celsius, petrol ignition point is 247 degree Celsius.

Nice
Intake valve ki size big hoti h so that volumetric efficiency increase ho sake then power increase hoga
Brother you mistake 11 no questions it may be increase but you told decrease please correction it
Yes u are correct it is by mistake correct option is a increase.
I have confirmed it in description of video.
Yess it will be increases
Thanks for replying sir 😊😊

No you are right bro
Efficiency decreses
आपको भी आयटीआय हो गया क्या
Well explained good and keep
Very helpful...Pls tell mcq book for ic engine...
Sir I think intake valve is more bigger than exhaust
So please varify.
Yes you are right. I already mentioned in description of video please check.
it's right bro
Thank you sir ...11th que. Ans increase
Right. Already mentioned in description of video
47 si engine related injetor
So nice keep it up
Thanks
Thank you Brother
Q11 - answer is a , efficiency will increase
Qst no 23 is wrong Size of inlet valve is greater in diameter as compared to exhaust valve
Right! I mention in description of video.
springs used for operation of valves of ic engine are?
23 ka b
Bhai 23 ka galat hai inlet valve exhaust valve se bada hota hai taki air jyada se jada suction Stoke me aa sake
Sir vidio is very helpful but some questions given the answer wrong
Please check description of video for two wrong uestion
Bhai sayad 20 ka ans spring hoga kyuki jo engine me pushrod nhi rahte usme camshaft se kulta hai
sir....plz tell me....the date of month of bokaro steel plant SAIL
Si engine use injcetor
valve are closed by spring
Gas engine also use s,i
20 ka c
भाई क्या ये IC Technology से releted है???
Q NO 23 :-
Ans should be (a) ie more
Sir g engine valves spring se close rehte hai
Any mistake in 11 th question?
No mistake
11 question answer is wrong??
what is source of these question??
PDF link irukuma bro
What is 3
23 question answer is wrong
Nice
