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
Inlet and exhaust camshafts (including followers)
Inlet and exhaust valves
Piston shape and squirt jets
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 F1 Sporting Regulations 38 of 38 30th October 2006
2. The supplier of a homologated engine and/or the team using the homologated engine must take and/or facilitate such steps as
the FIA may at any time and in its absolute discretion determine in order to satisfy the FIA that an engine used at an Event is
indeed identical to the corresponding engine delivered to and held by the FIA.
3. The FIA, in consultation with the TWG and the engine suppliers, will from time to time issue indicative information as to the
tests and inspection procedures to be applied.
