2007 FORMULA ONE SPORTING REGULATIONS

APPENDIX 4

ENGINE HOMOLOGATION
1. A homologated engine is an engine identical in every respect to either :
(i) An engine delivered to the FIA on or prior to 8 October 2006, such engine having completed two race
Events during the 2006 Championship season. However, any competitor who is unable to provide an
engine which has completed two races at this time may do so on 22 October 2006.
(ii) An engine delivered to the FIA on or prior to 1 March 2007, such engine being identical to one
delivered under (i) above but which has been modified by having any of the parts listed below
changed :
- Inlet and exhaust ports
- Combustion chamber
- Inlet and exhaust camshafts (including followers)
- Inlet and exhaust valves
- Piston shape and squirt jets
- Piston pins
- Connecting rod small ends and bearings
- Big end bearings and oil flow rate to them
Further changes, for car installation purposes only and which have no direct performance benefit, will
also be permitted. Such changes are limited to :
- engine pick-up points to chassis and gearbox
- fluid inlets and outlets
- fixings for engine ancillaries
- electrical sensor installations
- engine ballast weight attachments
- bodywork and skid block fixings
If a competitor intends to modify any of the parts listed above he must provide precise details of the
planned changes to the FIA on or before 15 December 2006. Once details have been provided in this
way no further changes will be permitted.
(iii) An engine delivered to the FIA after 1 March 2007, or modified and re-delivered to the FIA after 1
March 2007, which the FIA is satisfied, in its absolute discretion and after full consultation with all
other suppliers of engines for the Championship, could fairly and equitably be allowed to compete
with other homologated engines.
All such engines should be delivered in such a condition that the seals required under Article 87(d) can be
fitted. Engines will be held by the FIA throughout the homologation period.


2007 FORMULA ONE TECHNICAL REGULATIONS


8.4 Track signal information display
8.5 Medical warning system


In order to ensure that the relationship between these two sections
cannot change whilst the car is in motion they must be bridged by
means of rigid impervious supports (including any adjustment
mechanism) arranged such that no part of the trailing edge of the
forward section may be more than 250mm laterally from a support.
These rigid supports must :
- fully enclose the two complete sections such that their inner profile
matches that of the two sections. Their outer profile must be offset
from the inner profile by between 8 and 30mm and may not
incorporate any radius smaller than 10mm (‘gurney’ type trim tabs
may however be fitted between the supports) ;
- not be recessed into the wing profiles ;
- be arranged so that any curvature occurs only in a horizontal
plane;
- be between 2 and 3mm thick ;
- be rigidly fixed to the two sections. Some form of adjustment
mechanism between the sections may be incorporated for the sole
purpose of allowing adjustment of the sections relative to one
another whilst the car is in the pits ;
- be constructed from a material with modulus greater than 50GPa.
These supports will be ignored when assessing whether the car is in
compliance with Articles 3.9.1, 3.9.2, 3.10.1 and 3.10.5.



3.10.5 No part of the car between 75mm and 480mm from the car
centre line may be more than 500mm behind the rear wheel centre
line. Any parts of the car less than 75mm from the car centre line
and more than 500mm behind the rear wheel centre line must be
situated between 250mm and 500mm 200mm and 400mm above
the reference plane.


ARTICLE 4: WEIGHT
4.1 Minimum weight:
The weight of the car must not be less than 605 kg during the
qualifying practice session and no less than 600 kg at all other times
during the Event.





5.5.5 When establishing conformity with Article 5.4, the engine
will not include:
......
- oil tanks, catch tanks or any breather system connected with it to
them;
.....


5.8.3 The primary regulated voltage on the car must not exceed
17.0V DC. This voltage is defined as the stabilised output from the
on-car charging system.
With the exception of capacitor circuitry or coils being used solely to
provide ignition, any device with a current requirement greater than
50mA or a power requirement greater than 1W may only be supplied
at or below the primary regulated voltage.
Only capacitor discharge ignition systems (those which generate a
spark by means of closing a switch which then discharges a
capacitor through the primary side of the ignition coil), are permitted
to provide a voltage higher than the primary regulated voltage to an
ignition coil.
Other than any parts being used to supply a higher voltage to
devices such as those described in the previous paragraphs, no device may step up or increase the primary regulated voltage.



5.12.5 Metal Matrix Composites (MMC’s) – These are composite
materials with a metallic matrix containing a phase of greater than
2%v/v which is not soluble in the liquid phase of the metallic matrix.



8.4 Track signal information display:
All cars must be fitted with red, blue and yellow cockpit lights the
purpose of which are to give drivers information concerning track
signals or conditions. The lights must be LEDs each with a minimum diameter of 5mm and which are fitted in order that they are directly in
the driver’s normal line of sight.
Details of the light control system, which must be fitted to every car,
may be found in the Appendix to these regulations.

8.5 Medical warning system:
In order to give rescue crews an immediate indication of accident
severity each car must be fitted with a warning light which is
connected to the FIA data logger.
The light must face upwards and be recessed into the top of the
survival cell no more than 150mm from the car centre line and the
front of the cockpit opening and as near to the marshal neutral
switch, as described in Article 9.2, as is practical.
Details of the light and its control system may be found in the
Appendix to these regulations.


9.2 Clutch control:
...


- face upwards and be positioned on recessed into the top of the
survival cell no more than 150mm from the car centre line ;


10.3.4
...

Each wheel may be fitted with one or two cables, dependent upon
their performance when tested under FIA Test Procedure 03/05
03/07. If one cable is fitted it must exceed the requirements of 3.1.1
of Test Procedure 03/05 03/07 and if two are fitted each must
exceed the requirements of 3.1.2.



14.5 Rear light:
All cars must have a red light in working order throughout the Event
which:
- has been supplied by an FIA designated manufacturer;
- faces rearwards at 90° to the car centre line and the reference
plane ;
- is clearly visible from the rear ;
- is not mounted nominally on more than 100mm from the car centre
line ;
- is mounted between 325mm and 400mm 300mm (+/- 5mm) above
the reference plane ;
- is no less than 550mm 595mm behind the rear wheel centre line
measured parallel to the reference plane ;
- can be switched on by the driver when seated normally in the car.
The three two measurements above will be taken to the centre of the
rear face of the light unit.




15.4.7 Once the requirements of Articles 15.4.4, 15.4.6, 15.5.1,
15.5.2, 15.5.4, 15.5.5, 16.1, 16.2, 16.3, 17.1, 17.2, 17.3, 18.1, 18.2,
18.3, 18.4, 18.5, 18.6 and 18.8 have been met, panels no less than
6.2mm thick must then be permanently attached to the survival cell
sides. These panels must:
- in a longitudinal sense, cover the area lying between two vertical
planes, one 125mm forward of the cockpit entry template and one
50mm to the rear of the template. A 50mm horizontal linear taper
may be included at both ends ;
- in a vertical sense, cover an area which has been constructed in
accordance with Articles 15.4.6 and 18.6. This will not apply where
any radius permitted by Article 15.4.4 falls inside the minimum
permitted chassis width ;
- be constructed from 16 plies of Zylon and two plies of carbon,
precise lay-up details must be followed and may be found in the
Appendix to these regulations ;
- be permanently attached to the survival cell with an appropriate
adhesive which has been applied over their entire surface.
Cut-outs in these panels totalling 35000mm² per side will be
permitted for fitting around side impact structures, wiring loom holes
and essential fixings.



15.5.3 An impact absorbing structure must be fitted behind the
gearbox symmetrically about the car centre line with the centre of
area of its rearmost point face 300mm (+/-5mm) above the reference
plane and no less than 480mm 575mm behind the rear wheel centre
line.
It must also have a minimum external cross section, in horizontal
projection, of 9000mm² at a point 50mm forward of its rearmost
point. When calculating this area only those parts situated less than
100mm from the car centre line may be considered and the cross
section may not diminish forward of this point.


The rearmost face of the impact structure must be a rectangular
section no less than 100mm wide, this minimum width must be
maintained over a height of at least 130mm and each corner may
incorporate a radius no greater than 10mm. Between the rear face
and the rear wheel centre line no dimension of the area thus defined
may diminish nor may any part of the structure or gearbox which is
visible from below, other than the permitted radii, be higher than the
lower edge of the rear face.



This structure must pass an impact test and must be constructed
from materials which will not be substantially affected by the
temperatures it is likely to be subjected to during use. Details of the
test procedure may be found in Article 16.4.
Only those parts of the structure which genuinely contribute to its
performance during the impact test, and which are designed and
fitted for that sole purpose, will be considered when assessing
compliance with any of the above.


16.2 Frontal test:
...

For the purposes of this test, the total weight of the trolley and test
structure shall be 780kg and the velocity of impact 15.0 metres/sec.

The resistance of the test structure must be such that during the
impact:
- the average peak deceleration over the first 150mm of deformation
does not exceed 5g 10g;
- the peak deceleration over the first 60kJ energy absorption does
not exceed 20g ;

16.4 Rear test:

All parts which will be fitted behind the rear face of the engine and which could materially affect the outcome of the test must be fitted to
the test structure. If suspension members are to be mounted on the
structure they must be fitted for the test. The structure and the
gearbox must be solidly fixed to the ground and a solid object,
having a mass of 780kg and travelling at a velocity of
15 metres/second 11 metres/second, will be projected into it.

...
The resistance of the test structure must be such that during the
impact:
- the average deceleration of the object does not exceed 40g,
- the peak deceleration over the first 225mm of deformation does
not exceed 20g ;
- the maximum deceleration does not exceed 60g 20g for more than
a cumulative 3ms 15ms, this being measured only in the direction
of impact
