2s & 4S difference

Comparison between two stroke cycle diesel engine and a four stroke engine




Marine diesel engine guideline


The main difference between the two cycles is the power developed.

The two-stroke cycle engine, with one working or power stroke every revolution, will, theoretically, develop twice the power of a four-stroke engine of the same swept volume.

Inefficient scavenging however and other losses, reduce the power advantage .

Comparison between two stroke cycle diesel engine and a four stroke engine




Marine diesel engine guideline


The main difference between the two cycles is the power developed. The two-stroke cycle engine, with one working or power stroke every revolution, will, theoretically, develop twice the power of a four-stroke engine of the same swept volume. Inefficient scavenging however and other losses, reduce the power advantage .


For a particular engine power the two-stroke engine will be considerably lighter—an important consideration for ships. Nor does the two-stroke engine require the complicated valve operating mechanism of the four-stroke. The four-stroke engine however can operate efficiently at high speeds which offsets its power disadvantage; it also consumes less lubricating oil.

Each type of engine has its applications which on board ship have resulted in the slow speed (i.e. 80— 100 rev/min) main propulsion diesel operating on the two-stroke cycle. At this low speed the engine requires no reduction gearbox between it and the propeller. The four-stroke engine (usually rotating at medium speed, between 250 and 750 rev/ min) is used for auxiliaries such as alternators and sometimes for main propulsion with a gearbox to provide a propeller speed of between 80 and 100 rev/min.

func. applied for: 5

How much power produced onboard?
How much voltage?
How many generators?
How much voltage for lightings?
Why cant we use 220 volts motors and use 220 voltage thro out?
How are we getting 220 volts?
Principle of transformer?
Unlike motors is the coil moving to cut the flux?
Then how is the emf induced?
I said the current is alternating and it cuts the stationary coil which in turn cuts the magnetic flux inducing emf!
He asked are u sure?
Result: cleared

1 bottom end brg clearance ? i told at bdc, he asked y not at tdc, i told difficult for access but not satisfied
2 centrifugal p/p parts ? i told all, he den asked abt lantern ring y fitted ? wer exactly fitted & its purpose & from wer does it get cooalnt ? i told fitted on shaft for shaft cooling , i myself was not able to answer dis question satisfactorily since he went deep into it,
3 how wil u start ballast p/p ? i told check load on gen, den line up & start up. first i told without closing discharge v/v we start, den he interrupted & asked wont u close discharge v/v ? den i told yes sir we close it before starting,den he asked y we close, i told for reducing starting current in motor, but he told in some ships ballast p/p is started from cargo ctrl room, so wat happens in dat case ? wont d starting current rise in dat case ?? i told deywil inform us sir & we used to line up, but got stuck here.
4 how will u take tappet clearance ? i told bring piston to TDC, chck with flywheel mark, loose pushrod, cam position. he asked in flywheel showing two piston at TDC so now u take clearance side by side in both d cylinders ? i told we take in one cylinder only with loose pushrod, he asked watabt d other cylinder at TDC ??

result- need more preparation (which i myself felt wen i came out of d room)
so guys attending orals plz post questions so dat we come to know more new questions & prepare accordingly

(Mallu,softspoken,bald,takes classes in himt, very calm osm person lets u think and answer co operative, whomever he took today got atleast one paper so imagine hw good he is !!
pray that u get this person guys seriously !!! just keep telling what ever you know about the topic and he will be satisfied.)
Duration : 35-40 mins
Asked to write ship name and type
Func 3
1 : what is product carrier ? what all cargo u carried ? How many tanks u had ?
2 : single bottom or double bottom ? What is double bottom ?how the tanks are constructed ? 
3 : how far is the tank from the ships side ? how big is the ballast tanks ? have u gone inside and seen ?
4 : What fire fighting u had onboard ? what is low exp foam ? what is foam made up of ?
5 : What is flare , rake ?
6: What is Bulbous bow ?whats its use ?
Func 4B
1: Write the engine specs !what does it mean ? (6S50MC-C)
2: What is superlong stroke ? Why it is there ?
3: How exhaust valve works ? How it opens and closes ?
4: You have overhauled an exhaust valve, how will u check if it is working or not ? After fitting in the engine how will u check it ?
5: How will u check if u have overhauled the Air starting valve ?after fitting in the engine how will u check ?
6: You have engaged the turning gear, but the flywheel isn’t rotating. What will u do ?
7: What all interlocks and safeties present in Engine ?
8: How will u take Tappet clearance ?
9: How many inlet and exhaust valves present in Aux Engine ?
10: Explain in detail ME LO system.
Func 5
1: What voltages u had onboard ?what volt for lighting ? how volt is reduced ?
2: Insulated Earth & Earthed neutral system ?
3: 2 wire and three wire system something like that. How wiring in the lights how many wires what all they carry ?
4 : MSB safeties ?
5: A motor has come onboard after rewinding, what all checks u will do before installing?
6: How many terminals are there on a motor ?how will u connect it to the power supply ?
Func 6
1: Air compressor how is it cooled? 
2 : What is compressor ratio ? 
3 : How many relief valves it had?
Ok that’s all. I will recommend 4B to internal surveyor, he might ask u questions.
Finally the internal (fair,fat fellow wearing specs guess Bengali ) called us one by one 
Ok u have PASSED in 4B go and apply for 3,5,6

Following are some of the answers I gave him some are obvi wrong.
Func 3 
Told him I did not know hw long or big the tanks were, he asked me regulations I just told him I dono sir
Contents of foam he askd which I did not know, then asked where I did AFF blab la. Told him IDK sir
Naval definition I told him straight away I don’t remember them sir
Bulbous Bow : Reduces the frictional drag, aerodynamic of ship is btr thus inc efficiency of engine as less fuel used fr covering more dist, but he did not agree to the point I told
Func 4B
Superlong stroke increases eff and density of air increased hence more efficient 
(u can tell abt PLAN and for same power output engine size reduced no need extra unit) 
EXhvvcheched by giving spring air u can see the closing, aftr fitting u can chk by touching HP pipe to see if oil flows, then seeing the Exhaust temp, if nalfunction temp will vary from oder units 
(Primarily checked by the spring that’s present beside the vv that goes up n down during operation)
Air St vv checked by giving the &kg air from ship supply to the piston and see if it moves up or down,after fitting can be chked by sound and feel when the air comes for starting 
(aftr fitting open the indicator cock and chk if air coming or not if air comes vv is leaking)
TurnGear first call CE n 2E, elec supply nt coming then he said all elec connection is ok bt still not roting, I told him the teeth might be damged or some obstruction in flywheel , then I said main point The interlock might be malfunctioning
Func 5
told abt the transformer and principle 
Abt the two systems I told I dono sir
2 Wire 3 wire I was blabbering something I never understood what he wante to know so was beating around the bush
when mtr arrives chck physical condn then megger testing he askd what all tets u will do hw u will do I dint kno 
Connecting motor to supply dint knohw told u shud be knowing 
Func 6
Told some and made a Blunder by telling him No relief valve in first stage. He immediately stooped me and told hw will u relieve prs den there I cudnt answer so he told he enuf u can go
