Next generation Fast FID

Posted in News by

I'm very proud to be able to announce the next generation Fast Flame Ionisation Detector (FID) for hydrocarbon measurement from Cambustion — the FID600. This will be launched in Detroit next week at the SAE High Efficiency Internal Combustion Engine Symposium and World Congress Experience (WCX) conferences. Pay us a visit to booths 5 (HEICE) or 2113 (WCX) to see one for yourself.

The FID600 offers a new fully digital data platform, with 4 kHz data logging. All previous Cambustion fast FIDs relied upon analogue output of the fast HC concentration signal (though don't worry, for those who prefer it that way, the FID600 has analogue data too!) and thus the user had to make their own data logging arrangements. The FID600 has Ethernet, CAN and RS232 data interfaces too, as well as USB for external hard drives (and a generous internal hard drive too — 4 kHz data can take up a lot of storage!)

The FID600 is the 6th generation Fast FID, in a 32 year journey which goes right back to the very product which Cambustion was formed in 1987 to commercialise — the HFR100:

(We're actually somewhat short of pictures of the early analysers, so if you have any, do write in! Even better if they are still going strong. By the way, HFR stood for "High Frequency Response" — but then all our automotive emissions analysers are High Frequency Response)

Operator control is via a web-browser based interface (or via remote control over AK etc) — you no longer need a dedicated PC to run the instrument. The web interface includes a real-time data visualiser (or 'oscilloscope'). Here it is capturing the warm-start of a GDI engine:

This will work with the crank angle input as well (via a later free software update).

Beyond bringing the data handling up to date, we embarked on a detailed research programme over several years into overcoming compromises made in earlier generations in other important performance metrics, in order to achieve the fast time response. The result of this is that the FID600 improves upon the fundamental performance of the HFR500 in all these respects:

  • Linearity

  • Oxygen synergism (cross sensitivity)

  • Drift

  • Tolerance to sample pressure

The first three make the FID600's performance much more comparable to traditional bench analysers — but with the added advantage of the ultrafast time response as short as 1 ms. The flexible data processing allows easy combining of the fast data with, for example, exhaust mass flow if available, so cumulative emissions can be generated in real-time.

That final bullet point is really important for an analyser intended to be used in the exhaust or intake ports, with a turbocharger, or even in-cylinder. Here is a comparison of the FID600 and the HFR500's tolerance to sample pressure:

Finally, we've improved the soot filtration capability. The new soot filter makes the FID600 capable of all day operation even on dirty diesels engine-out, with a time response of 20 ms.

It's available in 1, 2 or more sample head versions. The brochure and full specs are now available here.

Looking forward to showing you the new fast FID in Detroit next week!
