Did someone of you monitoring combustion cycle test's by using high speed port pressure sensors, exhaust pipe back pressure sensor together with a combustion sensor in 2 stroke race engines?
If yes, which one did you use, piezoelectric (Kistler) or fiberoptic sensors?
Most conventional brand name logging systems use 50 to 1000 samples per second/channel, which is fine since the sensors attached to conventional logging systems such as EGTs, O2 sensors etc. are slow speed sensors. The high speed pressure sensors that have to be used with this equipment require very high speed data logging.
Very high sampling speeds are required to record this pressure data per degree of crankshaft rotation.
I have a quotation from a brand who promise me up to 3.600.000 samples per second total throughput with fiberoptic sensors!
The system is based on 1 combustion sensor with thermal compensation together with 1 exhaust port sensor, 1 transfer port sensor, 1 intake high speed port pressure sensor and 1 exhaust pipe back pressure sensor and finally the crank trigger.
Together with a specific 2 stroke software we achieve near 15.000 € with this fiberoptical technology.
I don't know what to do and hope that someone can guide me, knowing that it is a fact that the Kistler sensors are at least 5 times more expensive than this.
But, if it does not going to work at 100% it makes no sense to invest this money at all.
Any help will be appreciated.
Thank you in advance
