this 2 stroke is available in the arctic cat 2025 catalyst and riot.

I appreciate it

Yeah been there done that for real. You use all your air! But it will go! FYI it’s much more reliable on the automation than doing it by hand

1. Oil level kept Probably around around 60+ cu.m. (slightly above low level alarm in order to monitor any oil loss in the system). These are crosshead type engines so there should me no oil losses (except from the L.O. purifiers and minor oil leaks). No scheduled oil changes required for Main L.O. system, again because of the purifiers. There is also 6monthly Oil analysys that complies with flagstate/ class requirements. 2. Normally the M/E sits in the centerline of E/R with 5 levels- cylinder head level, 2 levels in the mid platform, bottom platform, and tank top level. Around the M//E for each level are machinery space protected with bulkheads and explosion resistant doors (i.e. ECR MSB/transformer/HV room, Stores room, D.G. Room, Purifier Room, Aux Blr room, compressor room, etc) 3. Only one thrust bearing assembly with 2 thrust pads ( each for ahead/astern). These are located between the aft most Main bearing and flywheel.

Aloha! Yeah I did an emergency fill in on the spirit last summer, apparently I am one of the only guys with a license left. Beautiful ship great trip to Hawaii

@steamman9193 Wow! I must have just missed you! I was on the Spirit from July- November last year! Was the SSTG gone yet, or still there? We ran the SSDG 24/7 for about 3 months... I was the 8x12 OMU...

Oh wow yeah I was there when it died. I was already signed off walking towards the gangway when there was black smoke coming out the stack. Had a few hours to get to the airport so went down and put everything back on. Last I heard it got wet and fried

@steamman9193 Yeah, it was down hard! They took the whole generator end off the ship and sent it to a repair shop. Progressive Electric. It was gone when I got there 7/3, and not yet back when I left on Oct.18th.. C/E Justin R. was there when I got there in July. Did you meet him?

Absolutely it is a lot but this particular model might be one of the most reliable engines ever made

Direct drive. Direct reversing. To stop the prop the engine has to stop

i always wondered about that too. thanks

Steam is much more compact and reliable but no where near as cost efficient

As @Steamman9193 said a Steam turbine is much more compact. I have seen a (I think it was) 40 000 hp steam turbine, and it was basically a couple of cubic meters in size i.e. a couple of washing machines, that's it - crazy! However the 2 boilers producing the super heated steam for the turbines (propulsion and aux power) was massive. I would say each boiler was maybe half the size of that MAN engine or maybe a bit smaller than that.

@@tjampman I was wondering about that. I believe there are other things taking up space on steam plants such as condensers, evaporators and reduction gearing. The other thing I was wondering about is if diesels are more efficient why aren't more being used in utility power stations vs steam. Maybe emissions?

This is probably the most reliable engine type ever made. 12 cylinders is a lot to maintain but we get outside assistance when needed

That’s the live sound as recorded by an iPhone 13. This engine is not that loud

@@steamman9193 Thanks. It sounds great. Some of my favorite relaxing ambience sounds. Just great!

They are very Loud!!

Those are great questions. This is a very very rough estimate but I’d put 10% of the volume of the hull is dedicated to machinery that would include auxiliary spaces like bow thruster and steering. Now the main engine space is restricted by the length of the engine basically the core area above it and around it is un usable for cargo so in this case the house is built on top of it and auxiliaries run the entire vertical and you also get the width to spread out your auxiliaries like generators and cooling pumps, anyway vessels this large have fairly spacious engine room you can generally drive a pallet jack around easily.

Yes spares are at the top and front of the engine

Not much difference from the video the time between pulses is just a bit shorter 100rpm is the max. We used to run these things hard all the time until Greta thunburg and her group got involved

That’s the hand throttle In case everything else falls

Haha I laugh quietly to myself when people start talking about horsepower and they don’t have 5 digits in their number.

Hopefully not! Pistons but really just the crown and rings are the largest replacement parts normally. Injectors and fuel pumps are smaller and much more frequently but bearings are usually good for life

It’s 1 guys job just to clean and paint plus we get others as needed.

About 90,000l. I’ve never added additives, purification and will top up occasionally but it barely uses any sump oil, however I normally burn 500l a day of cylinder oil

Big money when things are fine too, our fuel bill alone can easily exceed $100,000/day

They’ve really got us limited for fuel economy and emissions but it used to run at 2 Bar or about 30psi

@@steamman9193 That's about what I ran on my 16l cummins truck motor actually ran very clean never over fueled or over boosted it had 1.6 million on it and never had the pan or head off it.

2.4meters

Just some rough math but 1 liter/cylinder/ revoltion and that’s at eco speed

There’s 90 tons of lubricating oil in that engine

Low sulfur heavy in the ocean, ultra low sulfur diesel in the eca zones

@@steamman9193 ohh dam the leaks when u go into Eca zones

Because it’s a 2stroke with an exhaust valve and the fuel injection pumps are also driven off the camshaft. There are no intake valves and the engine must be supercharged/turbocharged to pump air into the cylinders

Wluld be fun to swap into my Hyundai i10! This makes about 1500 times as much horsepower 😅

@@AIRDRAC You could probably swap your whole Hyundai i10 into this engine 😅 And nobody would even notice 😅

@@2xKTfc Absolutely true! :D

Yeah we have at least 2. They are the biggest single engines I know of in the US fleet

@@steamman9193 On those RRF MARAD car carriers?

No, this is a containership that sails the pacific.

@@steamman9193 Oh I see, you must be MEBA!

Probably for $30,000,000

How fast are we talking about? The air police have choked this engine down but i ve done about 150metric tons/day

A MAN engine made by Hyundai

Really depends on how fast you go we are slowed down for fuel economy and it’s around 150 metric tons/day I worked it out for someone else it’s approximately 1 L per piston per revolution

No pork Muslim crew.

@@thereissomecoolstuff Turkey ham silly..made from the turkeys soft skin under the wing..

@@fredliperson9171 love it. You got it.

@@thereissomecoolstuff I'm old but not "Biden" old. ..

@@fredliperson9171 That engine room was very Bristol. The CE is on top of it. No one from the public will ever see it, yet it’s treated like it’s buckingham palace.

I think they make most of them under license very very few are actually made in Europe

Dali engine is significantly smaller this engine is 12 cylinders with a 98cm bore they had a 9 cylinder 90cm bore and 55,000 horsepower. Dali also has a more modern electronic fuel injection system that may or may not have impacted its ability to restart after blackout

Typo is 200cm stroke

This engine has 105,000 hours on it and has been running for 19 years parts like pistons get replaced but the main is all original

Wow that’s good stuff. I was watching another guys channel and he was saying the engine is directly connected to the prop shaft. So for astern, you have to stop engine and run it backwards. Which makes sense why probably all those engines are 2 stroke. But my question is, is there some kind of reduction/transmission that allows the engine to run without turning the prop shaft? I would think there has to be something to disconnect the two.

This one is relatively quiet

Why? The manufacturer calls it a 2 stroke
