Sulzer engine start

[marksalot2116]

thanks for the vid but i'm not looking for something quite that big...

[liverats]

SULZER ZA50s !! no rocker arms.

[ozzirt]

Sulzer Rules!

[Xlt92bassist]

does it have a pneumatic starting system?

[qwfreyvb]

@Xlt92bassist yes

[38Squid]

Those engines are SO big, its hard to tell they are engines at all.

[simionen]

awesum listening to that engine run....smooth! I work on ship engine room and always nice to hear the engines running while full away. cool!

[kratos32godofwar]

this is on ship i take it?? yes??

[ballsy101]

yeah, this engine is ok, I have one in my car.

[joffeloff]

@beepbeep999 They use dedicated starting air valves.. Air through the fuel valves?!

Also, the pressure should be minimum 20-25 depending on the engine, but usually 30.

[cornel10]

2 stroke marine engine, started with compressed air, but they miss the funny sound of the first piston stroke ( it's like an opened champagne bottle)

[mpwelk]

on helluva turbocharger

[rooieding]

@beepbeep999 Actually compressed air of about 30 bar is used to start the engine.

Starting air is admitted into the cylinders in firing order by valves actuated through a camshaft. The camshaft has 2 sets of cams - one set to start in forward direction and a second set for reverse. Once the engine reaches about 15-20 rpm air is stopped. The fuel pumps (driven by the same camshaft) are injecting fuel and keep the engine running

[seamanrob]

@rooieding I agree with everything you say, except you forget to mention that not all marine engines are reversing engines. Some of them only have one set of cams, with the directional control of the vessel controlled via the CPP system!

[Adamclarkson1]

how do you turn over an engine that big to start it??

[zii1965]

@Adamclarkson1 Sounds like they use compessed air, so that's my guess. (Have recently seen other engines being started that way, so I know that kind of starting exists...)

[BubbyStupidhand]

So that green box with that blue thing sticking out of it is the starter, right?

[bruvvamoff]

95000hp

[Hanglands]

Main engine:2 Wärtsilä New Sulzer type 9ZA 50 S, Engine output:21.600 kW Speed:21,5 knots

[gaktkr]

Whats its HP?

[7822welshsteam]

Watch ur language.

[hvguy]

a 9 cylinder? wtf

[deirup510]

odd number of cylinders is not uncommon for these large slow-speed engines

[fletch357]

No, not uncommon at all.. it is classed as a medium speed though.

[LolOfTheEpic]

nice :D

[tl22bq]

haha har du varit med när säkerhetsventilen släpper på sista cylindern hihi skanar inte bränslepumparna men jarehammar han är bäst

[iraqifreak]

what happens if they have a blown head gasket? can you find a replacement head gasket at autozone? and does a head gasket sealer work.. thanks

[charmand79]

yep...

I've also heard that a bit of good old high T resistant silicone will do the trick as well.. It all depends on the way you apply it.

you're welcome

[TheChiefEngineer]

Large engines have spigoted heads and do not require head gaskets...

[douro20]

Then how do they seal?

[ricturtle]

and a copper mix sealing ring

[kzbxvz]

Sulzer engines becomes popular in the 1960's.

[mysticalwonder7]

Cool! So complex! My kind of job in the future.

[DrunkHog]

What exactly is that hissing sound coming from, at the beggining? Sounds like compressed air rushing out some valves or something...

Does anyone know?! Thanks.

[iwestbury]

They use compressed air to start the engine

[dfwurob]

it's an air starter...

[DrunkHog]

Thanx - got it.

[samwattele]

They use compressed air to start the engine

[salemcripple]

They pump compressed air into the cylinders to start the engine.

[3Mudbone1]

@DrunkHog They first open all of the cylinder air cocks and roll the engine over a few times, then close the air cocks and start the engine immediately before recieving bells from the bridge.

[MrReaper2U]

What revs are they doing....like 300RPM or close to yeah?

[Erictheirritated]

Probably about 90 to 100 rpm.

[fletch357]

428 RPM is the norm for this engine, assuming 60hz being generated....

[nexprotein28]

Everything on ships is controlled from the Engine room. Executive command on board ships must get transferred to Chief Engineers and not Captains. Captains don't know how ships run. They only control wage calculations and provisions. Rest is marking GPS position on charts. Grade 3 level work skills required for being in executive command of ships as Master. Most unsafe to have Captains retain command on board a ship whose Engineering they have no clue about .

[geedude77]

Hilarious piece of text. You are sailing as an Engineer i guess ? Well, good luck with all your wisdom ;-)

[beatlenut909]

Wow - you know nothing my friend!

[nexprotein28]

Acually i manage a fleet. The more you go deeper you realize, the Captain is a very useless entity on board. Very low level of skills required. So tell me what skill sets are you talking about? I know because it's my Chief Engineers who haul every Captains arse from point A to B. Trust me most Ship Captains can't operate 90-% of Ship Emergency equipment. They do not have the requisite skillset to do that.

[commodore64738]

bullshitter

[nexprotein28]

Sorry i mentioned 90%. Captains cannot operate 99% equipment on board. They only know how to operate Radar, ARPA. Deck Officers are obsolete in shipping. Good only for greasing, chipping, painting stuff. Ships need qualified people. Not people pretending to be qualified and doing housekeeping stuff.

[bugsier5]

gladly that i'm a tug captain with my own boat!, (engeneer that can operate and handle a ship and engine's!) (LOL)

[mertvak]

so who do you work as on a ship?

im gonna be a engineer one day, after 4 years of studying...

[nexprotein28]

I run a fleet of ships under me. I sailed previously as a C/E. Now it is clear that Captains only know basic navigation and house keeping work. They depend on a C/E to get their butt shifted one place to the other. As a Ship Engineer you run the ship. The credit however is taken by people doing housekeeping. Very sick management system on board. Example: You have to do 4 years of study to become and Engr, you become a deck officer almost after high school.

[Rimouski418]

I do agree that engineers are very important on a ship, but captains are needed to clear paper work for the customs and all that kind of work. The C/O is also needed for all cargo operations (including calculation of stability). A ship is a small world in which everyone is essential. By the way, where I'm studying, engineers and deck officers are trained in 4 years...

[mertvak]

well here do deck officers study 4 years to

[miltos1993]

me too! :D

[TheChiefEngineer]

As an experienced seafarer with an Unlimited Chief Engineer's certificate of competency, I am astonished at you.

[nexprotein28]

Me too. All i am doing is stating the truth. Clearing customs, managing provision accounts are clerical functions. Navigation is done by midshipmen in Navies. Skill set levels required by the deck dept are low level and routine. Problem solving and analytical skills are not required and essential for Deck Officers.

[TheChiefEngineer]

I do agree the skills are very different, but please show a little more respect.

[nexprotein28]

Certainly they are. I manage a fleet. When cargo work is down due to machinery i see the Chief gets no assistance from D/Os except reporting there's trouble. Ships today are completely technical and all Officers must possess technical knowledge to share pressures in troubleshooting. My fleet has a huge shortage of Engineers. According to market demand Engineers should get a much higher salary. It's not happening. Things must change for the industry to reform.

[Snookenas]

Fine, so you run the engine. And when its running? You gonna sit there and watch it purr on idle when you dont have deck crew? I guess your gonna manouver the ship also.. Oh noes, you cant, your sitting in the engine room troubleshooting 24/7. I guess i'll just call the C/E next time i got 40 fishing boats who dont gives a shit on the 2M scale next time we pass northern denmark, maybe he can do the "basic navigation" for me since I have no analytical skills. Whats your fleet? Fishyboats?

[AndreiTupolev]

@Snookenas

Fishyboats? :-M

[sz42781]

Learn to swim,learn the Cleat Hitch, take some dramamine and come abord I have a mop with your name on it. Ill be in the captains quarters or the wheelhouse from time to time. Mabey ill let you hold the wheel mid Atlantic!

[437thx1138]

Problem solving and analytical skills are desired in anyone I interact with.

And I look for and find it in surprising places.

I know 2 people with Masters degrees that are dumb as a rock but did the time and kissed up. Unexpected competence saves many dire situations.

[myrryxmas]

@nexprotein28... one question i'd like to ask... when a helmsman runs a ship like the Exxon Valdez aground and spills oil all over the place, who's butt is placed in the sling? in other words, who's going to end up hauled into court and possibly do the time in prison?

the captain, or the chief engineer?

uh huh.  that's what i thought.

i don't dispute that engineers are overworked and underpaid, but it's the captain who's ultimately held responsible for everything aboard ship.

[joostvdz83]

Sweet. First i thought it was some kind of weird auxilary engine! But it is the main engine! You must have been in a fun loop with this ship, i can tell by the sizes.

[bronzeonion]

they use a sulzer engine in thw class 47 diesel locomotive built in the 60's

[SUPERIA75]

It really sounds pretty much like a ZA40.

[mpwelk]

Now, THAT'S a turbocharger!

[michigandon]

Are these direct drive reversing?

[amfan12]

Curios as to how the engine is reversible. Or is that possible to do the nature of the hydraulic valves?

[motorcyclehooligan69]

Well i have seen a 2-stroke diesel engine run in reverse so it may be possible. But depends on the design.

[dieselman1988]

they are reversible my friend is in the navy and they said they do

[JoshR343]

I don't know what is more pathetic, the fact that you use "gay" to describe engine startup, or that you spelt fucking with two q's.

[Chiefen66]

well, in the beginning you can here they blow trough the engine with starting air. During my more than 20 years at sea we have never used to turn the engine by the turning gear before starting.

[heiribuenzli]

Being a Sulzer service engineer for several years, I can only recommend using the turning gear to turn the engine before starting. I've gone out to fix damages resulting from hydraulic lock very often. The up side; I got to trave a lot!

[polina82]

sulzer makes the engine for the class 47

[Rogier21]

The turning is actually more used (also) for leaking cylinder heads that the cooling water doesnt stay on the head, otherwise your cylinderhead will just blow off!

[douro20]

There is one very critical step they didn't show here. The engine has to be flowed- that is, turned over without fuel- for several seconds to make sure there is no excess fuel in the top of the cylinders, otherwise the ignition of the excess fuel could cause a head explosion.

[scott93257]

That is one huge engine. It's a two stroke diesel right?

[mareflos]

Actually, it's two 4-stroke diesel engines.

[heiribuenzli]

It's a Z50 4-strocke engine. Only 5 or 6 have been built by GMT before Warsila has bought New Sulzer Diesel in the late 90's.

[kzbxvz]

What is is the name of the ship.

[thadutchguy]

@mareflos Aboard a Ro-Ro?

[mareflos]

Tor Selandia, yes it's a ro-ro.



[thadutchguy]

@mareflos Tor Lines has some nice vessels :)

[mareflos]

ooh, sorry, buddy! O_o

Ship = OK!

Crew = OK!

Engine room = death would be a relief

[thadutchguy]

@mareflos Hahaha, really!? I better shut my mouth :D so it is a big mess in the engine room?

[blondiebigtits]

only thing you can see moving is the little governor axle!(lol)

[mareflos]

But it's the sound, dude! Listen to the sound. Awesome!

[bugsier5]

my deutz 428 sounds much better!(LOL)

[MrHeizer42]

@mareflos boooring MTU sounds better !!

[mareflos]

It is a 9-cyl ZA50S.

[piratemak]

What model sulzer is this?

Looks like a ZA40 but with different heads.
