Technical Delegate's Report
Before the first free practice session:
An engine oil sample was taken from car number 23.
During the first free practice session:
The tyre starting pressures of all cars during P1 were checked.
The instantaneous fuel flow of all cars was checked.
The fuel temperature of all cars was checked.
The plenum temperature of all cars was checked.
After the first free practice session:
It was checked that all cars did not exceed 15000 rpm during the first free practice session.
The fuel pressure of all cars during the first free practice session was checked.
The logged pressure within the engine cooling system during the first free practice session was checked on all cars.
A fuel sample was taken from car number 03.
Before the second free practice session:
An engine oil sample was taken from car number 07.
During the second free practice session:
The tyre starting pressures of all cars during P2 were checked.
The oil consumption of all car numbers 44, 05, 10 and 27 was checked.
The plenum temperature of all cars was checked.
The instantaneous fuel flow of all cars was checked.
The fuel temperature of all cars was checked.
The fuel flow meter calibration checksum was checked on all cars.
After the second free practice session:
Car numbers 05 and 23 were weighed.
Car numbers 05 and 23 were checked for the following:
1) Bodywork around the front wheels 2) Front wing height and overhang 3) Rear wing height and overhang 4) Front and rear wing width 5) Rear wing configuration 6) Rear bodywork area 7) Rear winglet height 8) Stepped bottom 9) Overall height 10) Overall width
The minimum distance between the adjacent rear wing sections at any longitudinal vertical plane was checked on car numbers 05 and 23.
The IVT code and calibration checksums were checked on all cars.
The IVT temperatures were checked on all cars..
The ES state of charge on-track limits were checked on car numbers 44, 05, 10 and 27.
The lap energy release and recovery limits were checked on car numbers 44, 05, 10 and 27.
The maximum MGU-K speed was checked on car numbers 44, 05, 10 and 27.
The maximum MGU-K torque was checked on car numbers 44, 05, 10 and 27..
The MGU-K power limits were checked on car numbers 44, 05, 10 and 27.
The maximum MGU-H speed was checked on car numbers 44, 05, 10 and 27..
The MGU-K power model was checked on car numbers 44, 05, 10 and 27.
The custom software versions were checked on all cars..
The tyres used by all drivers during the sessions today have been checked.
A fuel sample was taken from car number 04.
The results of fuel analyses show that the fuels were the same as ones, which had been approved for use by the relevant competitors prior to the Event. Further the density change of the fuel samples taken today was within the permitted limits.
The engine oil samples have been analysed by FTIR spectroscopy and viscometry. The results of the FTIR analyses show that the sampled oils were consistent with reference engine oil samples which had been approved for use by the relevant competitors prior to the Event.
