Scania DI16 PDE. Marine engine en-GB 2 805 697. Operator’s manual - part 2

Engine data plate

The engine data plate indicates, in the form of a

code, the engine type, its size and applications. It

also indicates the engine power and the nominal

engine speed. The engine EU type approval for

exhaust emissions is indicated under Output,

where applicable.

The engine serial number is stamped onto the top

of the cylinder block at the front right.

Starting and running

Checks before first start

Before the engine is started for the first time, car-

ry out the maintenance items listed under First

start in the maintenance schedule. Check the fol-

lowing (also see Maintenance interval):

• Oil level.

• Coolant.

• Fuel level.

• Fluid level in batteries.

• State of battery charge.

• Condition of the drive belt.

Reductant tank

The illustration shows the component parts of

the reductant tank (buffer tank). You can access

the reductant pump in the tank by opening the in-

spection hatch (4) on the right-hand side of the

tank.

Reductant volume:

• Total volume: 30 litres (7.9 US gallons).

• Filling volume: 16 litres (4.2 US gallons).

Starting and running

Reductant pump

When the reductant pump is new, the check

valves may need to be slackened.

Note:

There may be two reductant pumps: one located

in the reductant tank and one located between the

main tank for reductant and the buffer tank.

IMPORTANT!

Blow the reductant pump suction nipple with

compressed air (approx. 6 bar) for at least 3 sec-

onds before starting the engine for the first time.

Reductant pump suction nipple.

Reset button on the reductant tank

The reductant tank has a reset button that can be

used, for example, when the tank is topped up for

the first time.

When the Scania EEC3 control unit checks fill-

ing, the following applies:

• If you keep the button depressed for 5 sec-

onds, the reductant pump operates for 30 min-

utes. This function can be used, for example,

when the tank is topped up for the first time

or after cleaning.

• If the reductant pump is operating and you

briefly press the button, the pump stops and a

fault code is generated.

The reductant pump can be started again by

pressing the button, thus also making the

fault code passive.

Reset button.

• If the level does not increase even though the

reductant pump is running, the pump is

switched off and a fault code is generated. If

you briefly press the button, the pump re-

starts.

Starting and running

Checks before running

Carry out daily maintenance as described in the

maintenance schedule prior to operation. See

Maintenance interval.

Starting the engine

WARNING!

Never use starter gas or similar agents to help

start the engine. This can cause an explosion in

the intake manifold and possible injury.

Only start the engine in a well ventilated area.

When the engine is run in an enclosed space,

there must be effective devices to extract exhaust

gases and crankcase gases.

IMPORTANT!

The starter motor must only be cranked twice for

30 seconds at a time. After that, it must rest for at

least 5 minutes before the next attempt to start it.

For environmental reasons the Scania engine has

been developed to be started with a low fuel feed.

Using unnecessarily large amounts of fuel when

starting the engine always results in emissions of

unburnt fuel.

1. Open the fuel cock if fitted.

2. Disengage the engine.

3. If the engine has a battery master switch:

Switch on the power by means of the battery

master switch.

4. Start the engine.

If the fuel tank has been run dry or if the engine

has not been used for a long time, bleed the fuel

system. See the section Bleeding the fuel system.

If run for extended periods under an extremely

maintaining the coolant temperature. At an in-

creased load the coolant temperature rises to the

normal value.

Starting and running

Alarm levels, engines with SCR system

If the engine is equipped with the SCR system,

the engine management system activates an

alarm at the levels below. The values refer to

overpressure, not absolute pressure. The alarm is

activated after 10 seconds.

• At an engine speed below 600 rpm and an oil

pressure below 0.7 bar (10.2 psi).

• At 1,200 rpm and with oil pressure below

2.2 bar (32 psi).

• At 2,100 rpm and with oil pressure below

2.8 bar (40.6 psi).

Charging indicator lamp

If the lamp comes on during operation: Check

and adjust the alternator drive belt according to

the instructions in the section Checking the drive

belt.

If the charging indicator lamp is still on, this

could be due to an alternator fault or a fault in the

electrical system.

Belt transmission

When the belt transmission is new, it may make

a squeaking noise when running. This noise is

normal and disappears after 50-100 hours of op-

eration. The noise does not affect the service life

of the belt transmission.

Starting and running

Bypass of the SCR system

If the SCR system has been activated and needs

to be bypassed in an emergency, this can be done

manually using the handle on the exhaust routing

valve.

Proceed as follows:

1. Remove the pin.

2. Remove the bolt.

3. Pull the handle to the Open position. See il-

lustration.

4. Lock the handle in the open position using

the pin and the bolt.

Labels for filled engine oil grade

When changing oil it is important to use the cor-

rect engine oil grade. The oil filler should there-

fore be clearly marked with a label for the filled

oil grade. However, there are only labels for oils

with Scania LDF approval and oil grade

ACEA E7.

Stick on a new label if the oil type or oil grade is

changed in favour of any of the oil types above.

Replace the label if it is missing.

If the oil grades below are used, you can order oil

filler labels from Scania.
