Vehicle Safety
The body structure
The aim of the design work on the OCTAVIA was to produce a protective body structure.
SP15-3
The FEM = Finite Element Method (computer model in which the body is broken down into
minute geometry elements such as rectangles or triangles) was used to process and calculate
the body structure for crash analysis.
This made it possible to take full account of the following important aspects as early as the
development phase
compliance with all existing safety regulations applicable.
ompliance with likely safety regulations, for example crash against a
moving barrier as is proposed from the year 2000 on.
A further development goal was to ensure that no
major parts such as the bonnet, side members, rear
doors suffer damage during low-speed crashes - up
to 15 km with overlap.
Satisfying these requirements is relevant for the
cars classification in the insurance
class.Copying for private or commercial purposes, in part or in whole, is not permitted

good classification.
One of the design features which contributes to this
is a specified front crumple zone at the side members.
The occupants are protected, the deformation is
absorbed by the front members and the remaining
side members do not suffer any damage.

The computer model made it possible to acquire valuable knowledge regarding the body cross
sections as early as the development phase.
These have been optimised in respect of their safety features and the materials used and form the
torsionally-stiff passenger cell.

Flush-bonded windows
Windscreen and rear window are flush-bonded to the body which increases the dynamic
stability of the body - an important factor in
the event of a rollover.
SP15-7
The measures listed below have been incorporated to offer the occupant side protection in the event
of a side impact:
wide sheet sections below the window line stiffen the doors
reinforcing tubes in the middle area of the door are capable of absorbing particularly
high forces by virtue of their cross section
foam-filled side impact absorbing elements in the doors for the pelvis and rib area
which move the occupants away from the hard outer parts.

Design
The seat belt tensioner operates on the
rotary piston principle with 3 working
chambers.
Seat belt tensioner and the inertia reel
form a compact component.
The installation point is the familiar
location for the inertia reel seat belt at
the bottom of the B pillar.
The seat belt tensioner system is activated by a mechanical sensor, which is
integrated in the seat belt tensioner, as
a function of the deceleration in the
event of a collision.

Engines
5-valve design
The output of an engine is dependent not only on the displacement and engine speed, but also in particular on how rapidly the charge cycle can be completed.
The power which an engine produces is all the more intensive the more fresh gas is able to flow into
the combustion chamber within the identical unit of time.
The 5-valve design makes it possible to achieve a high power output with a small displacement engine
while adjusting the camshaft of the inlet valves optimises the volumetric efficiency and the torque
curve of the engine.
The engine has three inlet and two exhaust valves which offer a large flow cross section. The inlet and
exhaust valves are each controlled by a camshaft.

The toothed belt for the camshaft drive is tensioned automatically by a tensioning device.

Engines
Camshaft adjustment of 5-valve engine
The camshaft adjuster makes it possible to
achieve improved volumetric efficiency in the
engine and to optimise the power output curve
(high torque and good elasticity at low rpm).
The timing and minimal overlap of the opening of
the inlet and exhaust valves are critical elements
for influencing the gas cycle operations.
SP15-31
The adjustable chain tensioner operates hydraulically, pressure being supplied by the
engine oil pump. The hydraulic cylinder moves the driving chain in its path on the basis of
signals supplied by the engine management system to the camshaft adjuster solenoid
valve.
The length of the chain at the one side is enlarged between the two driving gears of the
camshafts and simultaneously shortened at the other side.
The result of this is that the inlet camshaft is rotated vis--vis the crankshaft-driven exhaust
camshaft and the overlap of exhaust valve and inlet valve is thus reduced.

Timing is altered in line with
engine speed and load.

Electronic control
To satisfy the high demands in terms of fuel economy and emissions, the quantity of fuel injected and the injection timing are controlled with
the aid of the electronic system.
This task is performed by the Electronic Diesel
Control (EDC). It determines the quantity of fuel
and start of injection of the distributor injection
pump, controls the boost pressure, exhaust gas
recirculation and the glow period.
On the TDI engine this is the task of the diesel
direct injection system control unit J248.

DIAGNOSIS
Monitoring the condition of the electric plug and cable connections for cable break and short circuits.
REACTION
Stage 1: In the event of failure of sensors with correction functions, specified substitute values or analysable information of other sensors are adopted.
The driver usually is not aware of this.
Stage 2: Major faults which result in the failure of subfunctions, produce a reduction in engine output. The driver is advised of this by the glow warning
lamp flashing.
Stage 3: If the driver is no longer able to influence the power output of the engine
by means of the accelerator pedal, the EDC controls the engine in the fast
idling mode. This ensures that sensor functions of the vehicle are maintained. The car can continue to be driven with certain restrictions.
Stage 4: If reliable operation of the engine is no longer assured, the engine is shut
off by the fuel metering control. Should this not be possible because of
the fault, the engine is switched off through the fuel shut off valve (redundant system).

Engine/Gearbox Mounting
Gearbox mount
Engine mount
Pendulum support
SP15-50
The engine/gearbox mounting consists of engine mount, gearbox mount and the pendulum support.
The engine mount is a hydraulic mount (hydraulically damped rubber bush), while the gearbox mount
and pendulum support are designed as bonded rubber bushes.
Engine and gearbox mounts are positioned in the rotational axis of the power train about which the
engine/gearbox assembly moves when a torque is produced.
The pendulum support is located between subframe and gearbox. It absorbs only tensile and compressive forces. It is rigidly attached to the gearbox and flexibly connected to the subframe.
Housing
Benefit of this type of mounting:

Overview
The SKODA OCTAVIA has independent suspension and also coil
springs at the front and rear.
Front suspension with McPherson strut, rear suspension with springs
and dampers located in line.
An anti-roll bar at front and rear reduces the tendency of the body to
roll.
Disc brakes are fitted as standard at the front with drum brakes at the
rear (disc brakes also at the rear with the 92 kW engine version).
The suspension, the anti-roll bars (18x3 mm or 21.7x3 mm) and the
brake design are matched to the particular engine.

A bolt connects the shock absorber tubes by means of a clamp connection - as is familiar from
the Felicia - to the swivel bush.
The suspension is supported at the top at the body by means of a rubber bush.
A new principle has been selected for the pivoting of the anti-roll bar:
Positioned in front of the steering gear and located by means of the joint shaft.
The anti-roll bar is linked to the wishbone arm by coupling rods.
The advantage of this arrangement is a short leg length at the anti-roll bar with higher
efficiency combined with a smaller anti-roll bar diameter (smaller distance from pivot point of
shoulder bearing to the coupling rod offers greater torsion at the anti-roll bar with the same
spring compression).

Subframe
The subframe is attached to the body by four bolts.
The rear connection points are embedded in a rubber bush.

subframe
SP15-64
Extremely comprehensive test results have been incorporated in the design of the subframe.
The subframe is "crash-optimised".
The subframe buckles along an intentional line - behind the connection point of the wishbone
arm - downward if subjected to a certain force.
This is followed by a specific absorption of the energy in a crash by intentional permanent
deformation of the subframe to protect the passenger cell and the side members.
Caster
A caster of 40 mm has been adopted to reduce the traction influences on the steering and to
achieve excellent straight-running characteristics.
The steering efforts required for this caster setting (the larger the caster, the greater the effort
required for steering) is compensated for by the power-assisted steering.
Steering roll radius
A negative roll radius of 19 mm (with a wheel offset depth of 38 mm) has a positive effect on
directional stability when braking.
Service work on front suspension
No adjustment operations are required in the Inspection Service. When carrying
out repairs after an accident, inspect the entire suspension geometry.
Wheel toe can be corrected by up to 2 mm at the wishbone
The steering joint is mounted in slots for this purpose.
The position of the subframe can be altered by up to 4 mm.
This modifies the camber on the right and left side.
No adjustments are possible at the top body support.
46
Rear suspension
The rear suspension is a trailing arm torsion beam design with anti-roll bar.
Arranging the springs and shock absorbers in line one behind the other increases the
through-loading width of the luggage compartment compared to a conventional suspension
strut.
The axle beam is bolted at two points to the floor assembly and is supported by the coil
spring at two points to the body.
The shock absorbers operate as gas-filled shock absorbers.

The insulation/sound absorption concept
Numerous individual design details related to insulating and absorbing structure-borne
sounds have resulted in a very low interior noise level. Not all the components are immediately noticeable, as for example the connection of the rear suspension to the body (refer to
section on rear suspension), which together represents the entire concept.
The following important sound-absorbing concepts produce a reduction in interior noise:
Connection of front and rear suspension to the body

Corrosion protection
Sun, rain, snow, industrial and vehicle pollutants, surface water and stone chips - these
are numerous influences which the corrosion
protection of the vehicle has to resist.
In order to maintain the gloss, brilliance and
durability of the paintwork and to protect the
body frame from destructive rust, SKODA has
implemented two additional precautionary
measures on the OCTAVIA:

Cathodic corrosion
protection
58
SP15-85
The body panels are zinc-coated on both sides before leaving the steel mill.
The pre-treated panels are then shaped in the pressing shop to form the body parts.
The zinc layer survives the severe shaping processes in the pressing plant without any
damage.
When body panels are cut, zinc spreads over the bright metal surface of the cut and thus also
forms an additional corrosion-resistant protective skin.
Two types of body panels are used:
Electrolytically galvanized panels; these have a particularly fine zinc layer and
are used for all body outer parts.
Hot-dipped galvanized panels; they have the characteristic zinc flowers and are
used for non-visible body parts.
Repair work on fully zinc-coated bodies
Provided certain repair instructions are properly observed, welding work does not result in
any quality reduction of the body. Straightening work using a naked flame destroys the protective zinc layer (generally prohibited for supporting parts).
Welding methods
Preparatory work
Before commencing welding work, thoroughly clean the connection points. The zinc layer should not be damaged.
The contact surfaces of the weld areas should be treated with a
thin coat of cold zinc paint LKL 015001 (not in the case of shielded arc welding or brazing).
Repair instructions
You will find detailed repair instructions and details of the procedures regarding welding methods in the Workshop Manual.

The film thickness of the final paintwork after dip priming and the 3 water-based paint components of filler, top coat and clear varnish is 90 to 95 m.
Improved binder components in the filler and top coat produce an elastic paint structure.
The new water-based paints are considerably more resistant to chip damage.
The corrosion protection measures make it possible to provide a 10-year warranty against
perforation and a 3-year warranty for the quality of the paintwork.

Electrical System
The electrical system differs from that in the FELICIA in the design of the wiring and the fitting locations of the main components. The wiring looms are separated for engine, instrument panel, door and rear components. They are merged in three connector stations (in left

Electrical System
Central locking/electric convenience system
New!
The OCTAVIA features a convenient system for central locking with which
additional electrical components are closely linked.
The information is no longer transmitted by using individual cabling but along signal wires
(CAN network) and processed in control units (CAN = Controller Area Network - a means of
transmitting signals which were previously sent along the wiring loom).
Functions are not carried out through the CAN.

re special features
On models with manually operated windows, the central locking is not controlled
through the door control units but by the
central control unit.
Operational checks at the door are possible
within a period of 10 minutes even from
outside the car, without data transfer.
The central control units of the central lokking/convenience electrics differ in their
internal configuration depending on the
optional equipment fitted to the vehicle.
The fitting location and casings are identical.

The heating, as on the FELICIA, is controlled at the air side (temperature flaps).
It is equipped with a pollen filter, a 4-speed blower and recirculated air system.
It differs from the FELICIA in the installation position and in the installation point:
installed not in the engine compartment but in the interior of the car.
The rear compartment heating duct is divided and merges in the footwell behind the front
seats.
The rotary switches for the temperature flap, for the blower, for the air distribution and the
pushbutton switch for the recirculated air mode are conveniently located in the centre console.

Air Conditioning
A manually regulated air conditioning system is available as optional equipment in the
SKODA OCTAVIA.
The air conditioning system differs from the heating and ventilation system in the following
respects:
additional pushbutton switch with ON/OFF function for the A/C compressor
additional evaporator upstream of the heat exchanger for cooling and drying the air
the other familiar components of the refrigerant circuit which are filled with CFC-free
refrigerant R134a
The air distribution as well as the operation of the blower and recirculated air mode are identical with the heating and ventilation system. The blower should be set at least to stage 1
when the air conditioning is operating.
The air conditioning does not operate when the blower is set to stage 0 (risk of icing).
The LED in the pushbutton switch comes on when the air conditioning is operating.
