Foreword

This Operator’s Manual describes the handling and maintenance of Scania

DC16 Industrial Engines with EMS S6/PDE injection systems.
The four stroke V8 diesel engines have direct-injection and are liquid-cooled.

These engines have turbochargers and charge air coolers; see page 14.
Common applications are as power units in construction machines, generator

sets, earth-moving, railway and forestry machines as well as in irrigation

systems.
The engines can have different output and speed settings.
The normal output setting of the engine (performance code) is indicated on

the type plate, see page 14.

Note:

Only standard components are described in the Operator’s

Manual. Please see the manufacturer’s instructions regarding

special equipment.

In order to obtain the best value and service life from your engine, there are

several points you should bear in mind:

- Read the manual before starting to use the engine. Even though you may

have experience of Scania engines, you may find new information in

this Operator’s Manual.

- Follow the maintenance instructions. Good working order and service

life are ensured if maintenance is carried out according to the

instructions.

- In particular, read the safety information starting on page 10.
- Get to know your engine so that you know what it can do and how it

works.

- If necessary, contact an authorised Scania workshop. They have special

tools, genuine Scania parts and staff with training and practical

experience of Scania engines.

Note:

Always use genuine Scania parts during service and repair so as

to keep your engine in the best possible working order.

The information in this manual was correct at the time of going to press.

However, we reserve the right to make alterations without prior notice.

During the warranty period,

only genuine Scania parts may

be used during service and

repair; otherwise the warranty

will be invalidated.

Important

Environmental responsibility

Scania has always been very much at the leading edge when it comes to

developing and producing engines which are as environmentally friendly as

possible.
Major progress has been made on reducing harmful exhaust emissions as

required to be able to meet the stringent environmental standards stipulated

on almost all markets.
At the same time, we have been able to maintain high quality in terms of

performance and operating economy for Scania Industrial and Marine

Engines.
To preserve these qualities throughout the entire service life of the engine, it

is important for the operator/owner to follow the instructions on running,

maintenance and the choice of fuel and oil as outlined in the manual.
Other efforts to preserve the environment we all share are possible by

ensuring that the person carrying out servicing and maintenance always

makes sure that environmentally hazardous waste after servicing and repairs

(oil, fuel, coolant, filters, batteries, etc.) is dealt with and disposed of in

accordance with applicable environmental standards.
On a number of pages, this Operator’s Manual contains specially highlighted

text with instructions to help protect our environment during certain servicing

and maintenance work.

See example

Use a container to avoid spillage

when bleeding and renewing

components.

Help protect our

environment!

Certified engines

Emissions-certified engines have been approved in accordance with a special

certification standard. The certified engines supplied by Scania meet the most

stringent emissions standards which apply on European (EU) and non-

European (USA) markets.
Scania guarantees that all the engines it supplies of a certified type are

equivalent to the engine approved for certification.
The engine comes with a special certification plate which indicates the

certification rules (standard) to which the engine has been approved. See

page 14.
The following is required for the certified engine to meet emissions standards

once it has been commissioned:

- Servicing and maintenance must be carried out in accordance with the

instructions in this manual.

- Only genuine Scania parts are to be used.
- Injection equipment is to be serviced by an authorised Scania workshop.
- The engine must not be modified with equipment not approved by

Scania.

- Seals may be broken and setting data edited only once approval has been

granted by Scania in Södertälje. Changes may be made by authorised

personnel only.

- Changes which affect the exhaust system and intake system must be

approved by Scania.

Otherwise, the instructions in the manual in respect of running, care and

maintenance of the engine shall apply. The safety precautions described over

the next four pages must also be observed.

Important!

If servicing and maintenance are not carried out as specified

above, Scania can no longer guarantee that the engine will

comply with the certified design, nor can it take responsibility

for any damage that occurs.

Safety information

General

This Operator’s Manual contains safety information which is important so as

to avoid both personal injury and damage to the product or other property.

See also page 1.
The text highlighted in text boxes on the right of a number of pages is

important for engine function and in order to avoid damage to the engine.

If these instructions are not followed, your warranty may be invalidated.

See example.

Similar text may also appear in the text column, and in this instance it will be

marked

Note:

Important!

The warning text found in text boxes on the right of a number of pages which

is marked with a warning triangle and starts with

WARNING

is extremely

important and warns you of serious engine faults or incorrect handling which

may lead to injury.

See example.

A list of the safety precautions to be followed when running and maintaining

Scania engines can be found on the next three pages. Similar text can often be

found at the relevant maintenance points, and here different levels of

importance are attached to such text in accordance with the above

description.
All points are marked

, so as to indicate how important it is to read through

each point in this section.

For safety reasons, smoking is not allowed:

• In the vicinity of the engine and in the engine room

• When fuelling and close to the filling station

• When working on the fuel system

• In the vicinity of flammable or explosive material (fuel, oils, batteries,

chemicals, etc.)

Block the starting device when

working on the engine.

If the engine starts accidentally,

there is a

SERIOUS RISK OF INJURY.

Only use genuine Scania fuel

filters.

WARNING

Important

Safety precautions for running the engine

Daily inspection

Always carry out a visual check of the engine and
engine room before starting the engine and once you
have stopped the engine after running.
This will enable you to easily detect fuel, oil or
coolant leaks, or any other abnormalities which may
require rectification.

Filling with fuel

There is a risk of fire and explosion when refuelling.
The engine must be stopped and smoking is not
allowed.
Do not overfill the tank due to a risk of expansion,
and close the filler cap properly.
Use only fuel recommended in the service
literature. Fuel of the wrong quality can cause the
engine to malfunction or stop by preventing the
injection pump and injectors from operating as they
should.
This can cause damage to the engine and, possibly,
injury.

Hazardous gases

Only start the engine in a well ventilated area. The
exhaust fumes contain carbon monoxide and
nitrogen oxides, which are toxic.
If it is run in a enclosed space, there should be an
effective device to extract exhaust gases and
crankcase gases.

Starter lock

If the control panel is not fitted with a key operated
switch, there should be a lock on the engine room to
prevent unauthorised starting of the engine.
Alternatively, a lockable on/off master switch or
battery master switch can be used.

Starter spray

Never use starter spray or similar agents to help start
the engine. This can cause an explosion in the intake
manifold and possible injury.

Running

The engine must not be run in environments where
there is a risk of explosion as all of the electrical or
mechanical components can generate sparks.
Approaching a running engine always poses a safety
risk. Parts of the body, clothes or dropped tools can
get caught in rotating parts such as the fan and cause
injury.
For personal safety all rotating parts and hot
surfaces must therefore be shielded as much as
possible.

materials

Fuel and oil

All fuels and lubricants and many chemicals are
flammable. Always follow the instructions on the
relevant packaging.
All work on the fuel system must be done with the
engine cold. Fuel leaks and spillage on hot surfaces
can cause fire.
Store soaked rags and other flammable materials
safely so as to avoid spontaneous combustion.

Batteries

The batteries contain and emit oxyhydrogen gas,
particularly during charging, and this gas is
flammable and highly explosive. There must be no
smoking, naked flames or sparks near the batteries
or the battery compartment.
Incorrect connection of a battery cable or jump lead
can cause a spark, which in turn can cause the
battery to explode.

Chemicals

Most chemicals such as glycol, corrosion inhibitors,
preservative oils, degreasing agents, etc. are
hazardous to health. Always follow the safety
precautions on the relevant packaging.
Some chemicals, such as preservative oil, are also
flammable.
Store chemicals and other materials which are
hazardous to health in approved containers, marking
them clearly and storing them where they are
inaccessible to unauthorised persons. Always hand
in leftover or used chemicals to an authorised waste
disposal contractor.

Safety precautions for care and

maintenance

Stop the engine

Always stop the engine before maintenance and
servicing unless stated otherwise.
Prevent unwanted starting by taking out the starter
key where applicable and disconnecting the power
using the master switch or battery master switch and
locking them. Also put up a warning sign
somewhere appropriate, indicating that work is in
progress on the engine.
Working with a running engine always poses a
safety risk. Parts of the body, clothes or dropped
tools can get caught in rotating parts and cause
injury.

Hot surfaces and fluids

There is always a risk of sustaining burns when an
engine is hot. Therefore, take care not to come into
contact with manifolds, the turbocharger, the sump,
hot coolant and oil in pipes and hoses.

Lifting the engine

The engine lifting eyes must be used when lifting
the engine. Check first that your lifting devices are
in good condition and of the correct size to lift the
weight.
Extra equipment on the engine can alter the centre of
gravity, which is why you may need additional
lifting devices to balance the engine correctly and
lift it safely.
Never work underneath a suspended engine!

Batteries

The batteries contain a highly corrosive electrolyte
(sulphuric acid). Take care to protect your eyes, skin
and clothes when charging or handling batteries.
Wear protective gloves and goggles.
If the acid splashes on your skin, wash it off with
soap and copious amounts of water. If acid splashes
in your eyes, flush them immediately with copious
amounts of water and contact a doctor.
Dispose of used batteries through an authorised
waste disposal contractor.

Electrical systems

The engine must be stopped and the power
disconnected using the master switch or battery
master switch before working on the electrical
system.
External power supplies to extra equipment on the
engine must also be disconnected.

Electric welding

When carrying out welding work close to and on the
engine, remove the battery leads and the cables to
the alternator. Also remove the multi-pin connector
to the control unit.
Connect the weld clamp to the component to be
welded and close to the welding point, never to the
engine or in such a manner that the current can pass
over to a mounting.
When you have finished welding, connect the cables
to the alternator and control unit before connecting
the batteries.

Lubrication system

Hot oil can cause burns and skin irritation.
Therefore, avoid skin contact with hot oil.
Make sure that there is no pressure in the lubrication
system before starting work on it. Never start or run
the engine with the oil filler cap removed, as this
may cause oil to be thrown out.
Dispose of used oil through an authorised waste
disposal contractor.

Cooling system

Never open the coolant filler cap if the engine is hot.
Hot coolant or steam may spray out and cause burns.
If you have to open or remove a cooling system
component when the engine is hot, open the cap
very carefully and slowly to relieve the system
pressure before removing the cap. Wear gloves as
the coolant is still very hot.
Dispose of used coolant through an authorised
waste disposal contractor.

Fuel system

Always wear gloves when looking for leaks or
carrying out any other work on the fuel system. Also
wear protective goggles when testing injectors.
Fuel escaping at high pressure can penetrate tissues
and cause serious injury.
Never use non-genuine parts in the fuel and
electrical systems as genuine parts are designed and
manufactured to minimise the risk of fire and
explosion.

Before starting

Fit all removed shields before starting the engine
again. Check that you have not left any tools or other
objects on the engine.
Never start the engine without the air filter fitted.
There is a risk of objects being sucked into the
compressor impeller or of injury if you come into
contact with it.

EMS engine management

system

This engine has an electronic management system, EMS (Engine

Management System), with unit injectors (PDE) which provide each cylinder

with the right amount of fuel, at the right time, in all operating situations.
The EMS system consists of a control unit (S6) and sensors for speed, charge

air temperature and pressure, coolant temperature, oil pressure, accelerator

pedal/throttle actuation which constantly emit signals to the control unit.

With the aid of this input data and the programmed control software, the

correct amount of fuel and the correct injection time are calculated for each

unit injector under the specific operating conditions.
The EMS system sensors can also be used to emit signals to the instruments

in the instrument panel.
The control unit constantly checks the sensors to make sure they are

operational.
The control unit contains monitoring functions to protect the engine in the

event of a fault which would otherwise damage it. In the event of a fault, for

example, alarm level for low oil pressure or high coolant temperature, the S6

control unit sends a CAN message to a coordinator.
The main task of the coordinator is to pass on data by means of CAN

communication from the engine control unit to other control units and signals

to gauges and lamps in the instrument panel. The coordinator also has

monitoring functions.
When the EMS control unit or the coordinator detects a fault, the diagnostics

lamp on the instrument panel(s) comes on, and it stays on as long as the fault

is active. At the same time, a fault code is generated which can be read off via

the coordinator on the diagnostics lamp in the form of a flash code when the

diagnostics switch is activated. A flash code may consist of a number of

different fault codes.
Diagnosis and troubleshooting using Scania EMS Display is described in the

Operator’s Manual for Scania EMS Instrumentation.
If the torque reduction function is activated, the amount of fuel and the engine

power output are reduced to 70%, and if the engine shutdown function is

activated, the engine is switched off at programmed alarm levels.
A separate PC-based diagnostics program is used to read off the contents of

the flash codes. For an in-depth analysis of fault codes, contact an authorised

Scania dealer.
Reading off the fault codes, and descriptions of these, are also covered in a

separate document in the workshop manual, Engine Management System

EMS-S6: Troubleshooting.
Only authorised personnel are allowed to carry out diagnostic procedures

and program changes.
The positions of the sensors which emit signals to the control unit are shown

in the illustrations on page 17.
See pages 18 and 20 for a description of how to read off flash codes.
See pages 19 and 21 for a list of flash codes for the control unit and

coordinator.
