A Need for Fast Exhaust Gas Analyzers
The fast exhaust gas analyzer system combines cutting-edge technology with ease-of-use features to reduce test times, improve reliability and uptime while offering market-leading combustion and emissions measurement performance.
With strict tailpipe legislation, compliance often relies on controlling rapid transient events, such as sudden acceleration, gear shifts, or the frequent engine restarts typical of hybrid powertrains. Fast combustion gas analyzers provide millisecond-resolution data, allowing engineers to correlate emissions spikes directly with ECU behaviour in real-time. This immediate feedback loop is essential for calibrating fuel:air and aftertreatment systems to eliminate "invisible" exceedances, ensuring vehicles meet rigorous certification standards without compromising performance. Cambustion's fast combustion gas analyzer system offers the ultimate solution in supporting certification or research goals.
Cambustion's unique products have been deployed in engine test, and combustion development facilities around the world for 40 years, leading to a wealth of in-house application experience.
The Solution
The Fast Exhaust Gas Analyzer is an integrated solution combining three combustion gas analyzers into a single stack arrangement. The FID50 provides total hydrocarbon measurement by means of a flame ionisation detector (FID) and the CLD50 provides NO and direct NO2 measurement by chemiluminescence (CLD) and laser induced fluorescence (LIF). Finally, CO and CO2 measurement is done by the NDIR50 using non-dispersive infrared (NDIR). Individual heated link lines connect the analyzers to a heated sample splitter manifold (on the HSS50), from this a single heated line is connected to your exhaust sample point. 5 meters is the standard length, but custom lengths are possible.
A further advantage of Cambustion's solution is the ability to operate these analyzers individually, separate from the stack to utilise their full 15ms time response (3 meter sample line). This opens up possibilities for more dedicated or focused investigations.
Components:
- FID50 HC Analyzer
- CLD50 NO&NO₂ Analyzer
- NDIR50 CO&CO₂ Analyzer
- HSS50 Single Sample Line
Applications
In many applications, it is crucial to have a fast response time to detect and respond to changes in gas concentrations quickly. For example, in engine applications, fast response time is essential to monitor exhaust gases accurately and adjust fuel injection and combustion parameters for optimal performance, emissions control, and engine protection. A slow response time in this case could lead to poor fuel economy, higher emissions, and legislative exceedances.
The Fast Exhaust Gas Analyzer stack offers the ultimate solution in transient and fast response gaseous measurement with a broad range of applications. A versatile heated line system with adjustable cooling lengths allows for measurements in high temperature environments. Short resonance times within the sample line mean chemical composition is frozen at entry to the sample line, and there is negligible conversion of NOx species.
Data is comparable to conventional emissions equipment used for certification, but with the additional benefits of portability, time response and ease of use. Individual analyzers can be removed from the stack to be ran as a standalone product separately. Primary industry users are major engine OEM's and turbine manufacturers. This system is perfect for supporting your certification goals or combustion research applications, and enables reduced test times, improved development schedules and high uptimes.
