Indicator Diagram - PART 2 | Why Draw Card is 90°degree out of phase? Power Card | Imp | Watch Full

[@shonith91]

For people still wondering why 90 degree out of phase with piston its because,
When in phase,
At TDC piston speed is 0 so the stylus cannot show changes in pressure on the paper, the stylus movement is just too small to draw compression and peak pressure differently. In phase means the drum rotates same as the movement of the piston (up down motion of the piston= rotation of the drum).
When out of phase by 90 degree,
It means your drawing the diagram with the drum rotating at the TDC position. So basically your rotating the drum by hand when the piston is at TDC. (Piston at TDC= rotation of the drum). So you will get a clear drawing when at TDC.

Very nicely explained. Thanks

Thats a very good explanation of indicator diagram and the process, only thing missed in the procedure is drawing atmospheric line, it was asked to me during my orals and surveyor wanted to hear that first I will draw atmospheric line

[@pradgadagkar8557]

You did not explain how the draw card is 90 degrees out of phase

[@rajadurai5090]

yes i not understand 90 degree out of phase

[@amitkumarpandey2862]

we are pulling the lever with hand, timing it in such a way that its 90 degree out of phase, power card mai we dont have any control on the drum

[@chauhan943]

Good clarity of explaination. Keep up the good work. 🎉

[@MistCatcher-pd8id]

Appreciate the hard work you have put into it. Good job.

[@kartiksood4504]

why at 90 degrees , at max piston speed , you are saying we are able to amplify the dia..? what's maximum piston speed got to do with amplification of a combustion area diagram ?

[@sandeshlokare2595]

Making such models & creative diagrams helped us a lot... Thank you... making it happen for us... Very grateful for ur efforts... Keep going... 💯💪🏻

[@CLASS4ORALS]

Thanks alot for your feedback

[@meetsheladiya6114]

Finally I have understood the concept

[@salehsane3249]

Very good 👍🏻 I was needed it why it is called 90 degree

[@flyingbird8469]

Dear sir, i am very much grateful to you regarding this study purposes. Please do this types of marine engineering study on video, we all the juniors are so beneficial. Waiting for your new upload from Bangladesh.

[@CLASS4ORALS]

Thanks alot. I will surely come up with more videos.

[@abhishektalajiya1987]

Loved this one also, part 1 was awesome, that was the easiest way to explain.❤️ thank you so much

[@CLASS4ORALS]

Thanks alot 😊😊

What are the two phases of draw card?

[@sumitvelani7434]

With help of draw card can we calculate Pmean nd power

[@mohammadsharifullahmondal4976]

Draw card is not for power calculation. Power card is used for power calculation. Draw card is for assessing injection and ignition characteristics which cannot be inferred directly from the power card.
