02.3.1 General

In order t o prevent corrosion, sca le deposits or other deposits in closedcirculating w a ter systems, the wa ter must be trea ted with a dditives. B efore treat ment, the wa ter must be limpid and ha ve a ha rdnessbelow 10 d° H , a chloride content of less tha n 80 mg/l and a pH va lueabove 7. Further, the use of approved cooling water additives ismandatory.

Caution! Distilled water without additives absorbs carbon dioxide from theair, which involves great risk of corrosion.

Sea water will cause severe corrosion and deposit formation even ifsupplied to the syst em in sma ll amounts. Ra in wa ter ha s a high oxygen a nd ca rbon dioxide cont ent; great riskof corrosion; unsuita ble a s cooling wa ter. If risk of frost occurs, plea se cont a ct th e engine man ufa cturer for useof anti-frost additives.

Lubrica ting oil samples should be ta ken w ith t he engine in opera tionimmedia tely a fter t he lubrica ting oil filter on t he engine. Alwa ys ta kelubrica ting oil sam ples before a dding fresh oil to the system.02A.5.1.2 Fuel oil sampling

Fuel oil samples can be drawn from different places in the fuel oilsystem, " a s bunkered" or "before th e engine" (a fter fuel oil separ a tiona nd filtra tion) a re perha ps the most common sa mple types. From t heengines point of view th e most import a nt fuel oil sample is na tur a llythe one which enters th e engine, i.e. ta ken a fter fuel oil separ a tion an dfiltration. But if for example fuel oil separator efficiency needs to bechecked sa mples should be ta ken just before a nd a fter th e separ a tor.It is not a dvisable to ta ke sa mples from ta nk bott om dra in va lves, thesewill probably contain high levels of water and sediment and thesamples will not be representative of the bulk phase.

02A.5.2 Dispatch and transportation

Place the bottle with the "Ziploc" bag inside the IATA carton box andfold the box according to the assembly instructions given on the box.E nclose a copy of the " B unker Receipt" , if a va ilable, before closing t hela st fla p on t he IATA cart on. Ch eck the DNVPS Air Courier Directory a nd use a ppropria te labelfor the IATA carton box to ensure that the sample is forwarded to thenear est D NVP S la bora tory. Complete the courier dispa tch instr uctionson the side of the IATA carton. Fill in the DNVPS universal accountnumber (950 500 010) to prevent rejection from the courier company(DH L). Complete the P roforma Invoice Form a nd ta pe it to th e outsideof the IATA car ton.

Ca ll th e a ir courier directly a t t he number as indica ted in the AirCourier D irectory a nd r equest u rgent pick-up. When t he courier a rr ivesyou will need to complete an Airwa y B ill.

1 Engines with built-on cooling water pump: Idle the engine 1min before stopping. The pre-heating pump to be started. Engineswith separate cooling water pump: 1 min idling will be enough,but t he w a ter pump should run for some 5 min more.


03 - 3


38/256

2 Stop the engine by moving th e stop lever int o stop position. Thetime of slowing down offers a good opportunity to detect possibledisturbing sounds.

03.3.3 General

Caution! When overhauling the engine, make absolutely sure that the auto-matic start and the priming pump are disconnected. Make also surethat the starting air shut-off valve located before main starting valveis closed. Otherwise it might cause engine damage and/or per-sonal injury.

Move stop lever into STOP position.

The lubrica tin g oil syst em on a st opped engine should be filled w ithoil every second d a y by priming t he engine. At the sa me time, turn th ecra nksh a ft int o a new position. This reduces the risk of corrosion onjourna ls a nd bea rings w hen t he engine is exposed to vibrat ions.

03.4 Normal operation supervision

If an a larm limit is reached and a n a larm is a ctivat ed, the engine situa tionis a lready serious. All necessary count ermeasures must be ta ken to remove

this emergency condition a nd return to norma l operat ing conditions. Asthe a bnorma l opera ting situa tion ma y cause dama ges to the engine, allefforts must be put into return ing to the norma l opera ting situa tion insteadof just w a iting for a n a utoma tic shut down of the engine.

03.4.1 Every second day or after every 50 running hours

1 Read all temperatures and pressures and, at the same time,th e loa d of the engine. All tempera tu res a re more or less dependent onthe load, and the lubricating oil, cooling water pressures (built-onpumps) are dependent on the speed. Therefore, always compare the

va lues rea d w ith those at corresponding load a nd speed in t he Accep-tance Test Records and curves. Guidance values are stated inchapter 01. The cha rge air t emperat ure should, in principle, be a s low a s possiblea t loa ds higher t ha n 60 %, however, not so low tha t condensa tionoccurs , see Fig 03-2.

2 Check the indicator for pressure drop over gas and liquid fuelfilters. When t he pressure drop over the filters increases, th e feedpressure to the engine might become too low and the output of theengine must be decrea sed. Too high of a pressure drop ma y a lso result

in deformation of filter cartridges.


03 - 4


39/256

3 Check the indicator for pressure drop over the lubricating oilfilters. Too la rge of a pressure drop indicat es clogged filter car tr idges,which results in reduced oil filtration when the by-pass valve is open.Reduced oil filtra tion results in increased w ear . Vent filters a nd, if no

improvement, cha nge th e ca rtr idges.

4 Check the oil level in th e oil sump/oil ta nk. E stima te t he a p-pearance and consistency of the oil. A simple control of the watercont ent: A drop of oil on a hot su rfa ce (a bout 150° C), e.g. a hot-plat e. Ifthe drop keeps “quiet”, it does not contain water; if it “frizzles” itconta ins w a ter. C ompensat e for oil consumption by a dding ma x. 10 %fresh oil a t a time.

5 Check the ventilation (de-a era ting) of the engine cooling w a tersystem. Check that the leakage from the telltale hole of the coolingw a ter pumps ar e norma l (slight ).

6 Check that the drain pipes of t he a ir coolers a re open.

7 Check that the telltale holes of the oil coolers and the coolingw a ter coolers a re open.

8 Clean the compressor side of the turbocharger by injectingw a ter. See th e instruction ma nua l of the turbocha rger.

9 Running in diesel mode with no pilot fuel injection, check thequa nt ity of leak fuel.
