MAERSK MISSOURI - Main Engine

The guy who told me that was a diesel mechanic on an ice breaker for the the coastguard, dosent mean its true although he was definatley a master mechanic, but the only two reasons I entertained the thought was I trust the source, that is if he even knew it to be true for sure, and because although it is only a little diesel @ a time that little diesel goes a long way as far as potential energy in an engine. Wonder where he heard that :-(

I never heard that before, but it sounds bogus. Each combustion cycle on a train engine (MUCH smaller than that pictured) uses only a tiny bit of fuel, finely atomized for complete combustion. Nowhere near the amount of energy in that shot of fuel versus a couple sticks of dynamite.

Is it true that one single blast in a single cyilinder of a freight train engine = 2 sticks of dynamite?

Heavy Fuel, aka Bunker Fuel, aka HFO, is cheaper than light oil (MDO).

Also it has good heating value. But all these marine engines can run off either type of fuel just by switching a 3-way valve from your different service tanks.

thanks

If you think how much fuel is used by an engine that is the size of a 3 storey building, you want it to run on the cheapest fuel possible, which is basically industrial sludge from refineries ('heavy' or 'residual' fuel). It is very thick so it has to be heated up to over 100 degC so it is then possible to work in the fuel injectors. These are slow speed 2-stroke diesel engines

why heavy

The engine runs on heavy fuel oil, which is pre-heated using steam

I agree 100%

is that steamengine? heated with diesel?

Hehe. Nice engine, but not even close to the Wärtsilä-Sulzer RTA96 Turbo two stroke diesel. 14 cylinder version puts out over 108 000 hp :D

yeah it's vrey huge! especially when a Mearsk vessl engine!even they are vry big hose vessels, but when i was travelling as an engine student this summer, i've realised that big and heavy vessel are fastre than the small ones!which is not like cars, i've nerver seen a normal truck giving more than300km/h!lool!in my case, i was working ona 175 meter container vessel, our speed was 17knots, weither 245 meter container vessl was sailing at 25 knots!!

the biggest is 98 mc-c " or e", and the biggest on paper is 105 mc

looks like a ABB turbocharger...VTR type.

wonderful, i miss my sailing days, that sound of engine, that T-Time with biscuits and coffee , and my filipino oiler who used make me coffe.
