Marine Diesel Engine (K98MC)

Most modern ships use a reciprocating diesel engine as their prime mover, due to their operating simplicity, robustness and fuel economy compared to most other prime mover mechanisms. The rotating crankshaft can be directly coupled to the propeller with slow speed engines, via a reduction gearbox for medium and high speed engines, or via an alternator and electric motor in diesel-electric vessels. The rotation of the crankshaft is connected to the camshaft or a hydraulic pump on an intelligent diesel. The reciprocating marine diesel engine first came into use in 1903 when the diesel electric rivertanker Vandal was put into service by Branobel. Diesel engines soon offered greater efficiency than the steam turbine.

1. Lions gate bridge is one of most shittiest ships i have even been on.

3. If you are in this line of work, you would understand this is big boys toys. I fucking love it. I eat and breath this all day every day
4. So called "diesel" engines don't exist any more. Oh ? That "diesel" train is run by polyphase electric motors,as are huge arctic ice breakers, etc. It could be a diesel fuel but it turns a polyphase electric generator that is rectified to DC by modern hi-power semi-conductors. and then converted back to AC. Why ? Because the electric motor that turns the "wheels" turns at speed (RPM) of electric frequency supplied, no gearbox, etc required. Motor can operate at peak efficiency, carefully checked at production. Motor, speed, all controlled by computer. The U.S. company is Baldor, such engines to thousands of HP. I'll add info.
   U.S.S. Nautilus (nuclear engine) sea trials began 1955, 2 years traveled 60,000 nautical miles before the partially used fuel was replaced. If it were diesel submarine would have required 720.000 gal of fuel. AND newish Russian Lada submarines use the Project 677 Sterling (cycle) engines that have many advantages over the U.S. nuclear "boomer" subs in the Pacific. e.g., they are undetectable, ideal hunter-killers, and brings an end to the U.S. aircraft carriers era. They are now obsolete.. kunosoura
5. Use of fuel per 100km ?
6. 200,000 liters of diesel per day. so each day it burns 200,000 euros if its filled up in europe. I wonder how is that feasible for them?
   I'm sure if it was solar and hydrogen fuel cell it would be more efficient.
7. hey good very good high technology
8. "...it moves the Titanic-sized ship..." Um, The "Titanic" would have looked like a tug next to this ship!
9. why fuel consumptions in tons?
10. nice
11. Great! Maybe turbocharged Zhou Engine will replace
    this diesel engine. The former is far smaller and higher thermal efficiency. Please

12. Comushing is not a expolosjon,
13. Lj
14. But can it fit in my Honda?
15. I like all vids about technology or mechanic, why this video has only 1 like and 90 dis - like ?
    I make the 2 like!😆
16. Hola amigo, una pregunta, tienes el video con subtitulos en español? me lo podrias pasar o subir a youtube?

18. hi Andrew Rai. I see your point, however a typical semi diesel operates at a crankshaft speed of 2500 rpm max. with max torque at about 1600 to 1800 rpm. An engine like the BW/M.A.N typically operates at a crank speed of 95 rpm. and produces enormous torque wich is what's needed in a massive marine propulsion engine. To achieve a similar amount of torque from a high reving engine, you would probably need 500.000 HP. This is of course only playing with numbers as it is not practically possible to achieve this enormous amount of torque using high speed diesels. also, a semi has a gear box with reductions and multiple gears (speeds) to convert HP to torque, a marine propulsion engine like the BW/M.A.N does not have a reduction gear box, but is coupled directly to the massive propeller. A bit like trying to get your semi to move and drive in top gear. also a marine propulsion engine in a container ship clocks up hours equal to 3.000.000 Km per year. For this application there is no alternative to the massive, high torque slow speed monster.

20. The history of ships is incomplete. what would happen if this ship was closely connected to 20 others?????????????????????????????
