Main Engine Performance and Power Calculation

[@babusuganthan9592]

Thank you very sir for clear explanation of power calculation, Hats of sir

[@sultanhussain6051]

Excellent Viral ,, love from Pakistan.

[@gurbirsingh8232]

Nice information

[@mikauvq7078]

indicated power is the power develop inside the engine.
effective power is the power develop outside the engine.?

[@PankajKumar-yi1on]

Thank you so much sir❤

[@toymaniaa]

I work in the energy efficiency department of a shipping company. Sadly very few C/Es know the calculation of SFOC, let alone its significance.

[@mikauvq7078]

i would like to clarify something sir, I dont know if my formula is wrong.
Indicated power = mean Indicated pressure x L x A x Number of stroke per sec
Effective power = mean effective pressure x L x A x Number of stroke per sec
mean effective pressure = mean indicated pressure - losses (1.25 bars constant for model L35MC) some people use 1 bar for the losses if they dont know the constant.
thats why im confuse for
Indicated power = mean effective pressure x L x A x Number of stroke per sec

Very well explained sir, please explain how to take light spring diagram on mechanical indicator instrument.

[@chiefengineerviraldungrani9581]

Sure ll try to make one when I go aboard ship this time

[@barunmishra2015]

In plan formula, we are getting mean indicated pressure or mean effective pressure?

How to calculate brake power from indicator power

[@Sea_monk]

Sir 90 degree out of phase samajh nhi pa rhe hai....during taking draw card

[@chiefengineerviraldungrani9581]

90 degrees out of phase card mein jo indicator drum hai... Usko haath se kheechte hai jaise video mein dikhaaya hai... They way he is taking card.. And in phase card yaani ki Power Card mein.... Drum ki string ko cam follower se connect karte hai... And fir drum cam follower ki movement follow karke gumta है... Generally woh cam follower... Fuel pump ke baaju mein rehta hai... Exhaust valve ke upar indicator kaisa rehta hai... To check opening and closing of exhaust valve... Waise hi same dikhta hai cam follower... Next to fuel pump..

[@balmoravalirii9653]

Please make an english version of this vlog..thanks

[@chiefengineerviraldungrani9581]

Sure will try and make one.

[@simransingh1885]

why is there early ignition when pcomp is low? I am not able to undersrand that part. Because with low pcomp, the temp of air should also be low.

[@chiefengineerviraldungrani9581]

Low P.comp is due to Broken Piston rings. Since the rings are broken the air the air is not able to reach the compression pressure.
Early ignition is due to Fuel Injection timing VIT rack... It can be adjusted... Or the shims in the fuel pump can be adjusted for timing.
VIT is based on CCAI number of Fuel.. It's a FQS fuel quality setting.
Fuel with low CCAI will burn quickly.
Fuel with high CCAI will take time to burn.
There will be ignition delay for sure. But higher CCAI. will alter the ignition timing.

@@chiefengineerviraldungrani9581 thank you for the clarification

[@rajatwalia01]

that mean height gives mean indicated pressure or mean effective pressure
its very bothering

[@ahmetkemalgokbaba1889]

Bro
Title is English but speaking is???

[@chiefengineerviraldungrani9581]

Speaking is both Hindi nd English mix.
