Whats that at 4:37?

[bjornengineer]

I'm inside the intake air manifold of the main engine of the vessel. Those holes are the scavenge ports in the cylinder liner of the engine, the openings through which the air is drawn into the combustion chamber, to be burned together with the fuel (I'm sorry, maybe you know all this...:$).

Thanks for watching!

I have another question. How do they keep air from getting into the cylinder when the piston is above the scaveng ports?

[bjornengineer]

The scavenging air pressure in this engine is around 1,5bar. On the other hand, during compression, the air pressure inside the cylinder inmediately increases above 1,5 bar, reaching 25 at the end. Therefore no air is drawn into the cylinder. However, well perfoming piston rings should isolate the combustion chamber, to prevent the compressed air of the chamber from leaking out.

Take care!

But when the piston comes down and pushes air out, won't that surge the turbo?

[bjornengineer]

Hi! I hadn't seen the reply! Well, as the intlet manifold is common to the 7 cylinders and they're not at admission/intake at the same time the flow of air through such a wide manifold shouldn't make the common turbo surge to much...I guess.

Take care!

Great, but I preferred "heavy metal sound" from the engines themselves :-D
