Very good apart from someone trying to show how clever they are with the captions. They are difficult to read at first, the font is totally unsuitable and I don't want to have to chase it around the screen with my eyes, just put it on the screen clearly and cleanly.
They said something like that when boiler pressures rose to a level where they could no longer fill them by gravity from the seawater outside. Progress is ongoing.
They're not building engines at Frederikshavn anymore. MAN killed their very best factory in 2012. Today it's only a new testcenter for future engines.
What a superb presentation. Very well done.
it is fantastic
the big two stroke engine is the most beautiful motor!!!!!

how big is your ship?
20.000 BRT?
This is very common and accepted in the longhaul/vocational truck market.

The engine graphic depicts a compressor not an engine, the exhaust valve opens near bottom of power stroke, not at start of compression stroke.
muy buen video...
saludos! :)
So how do you suppose we will propel our ships?
MUY BUENO .
a properly designed (and built...) electro-mechanical system has the same or even smaller chance of failure then a pure mechanical one...
I can't see what that has to do with the point of my comment.
In any case, a feedwater pump is thermodynamically much more efficient than an injector.
electronic injection would seem to eliminate the efficiency problems inherent in the two stroke concept..
Power (kW) the 2 strokes look good to me wikipedia Brake specific fuel consumption

Pode poluir e consumir um pouco menos, mas da muito mais problema, muito menos confiável.
somebody have a book about this system?
marine.man-es.com/applications/projectguides/2stroke/content/printed/G60ME-C9_5.pdf
Yo lo he montado
ilike
corn reporter self cup since hot greatly.
Very poor video and graphics...
untill it break haha! yes yes I know that...even so still wary of purely electronic valve actuation....just sayin...
oh dear electronic valve actuation...sounds like an accident waiting to happen...with mechanical s at least you have half a chance of a running repair
