Fast Exhaust Gas Analysers

The Cambustion HFR500 offers two-channel measurement of Total Hydrocarbon by the industry-standard flame ionisation detection (FID) method. A time response as fast as 0.7ms (T_10-90) is possible. This is widely used for cold start calibration work and in-cylinder measurement.

The two-channel CLD500 measures NO with T_10-90 of 2ms by chemiluminescence detection. Optional NO_x convertors are available to measure NO and NO₂, used particularly in Diesel applications.

The NDIR500 provides two-channel simultaneous measurements of both CO and CO₂ (4 data channels). This allows transient EGR measurement, fast AFR estimation and catalyst efficiency measurement with a time response of 8ms.

In-cylinder Sampling Valve

The CSV500 is an in-cylinder sampling valve system which can be combined with Cambustion Fast Gas Analysers to allow cycle by cycle measurement of cylinder contents.
This technique is particularly useful for evaluating in-cylinder residuals, for example when studying the effects of variable valve timing.

SPR100 Spark Plug Resistance Monitor

The Cambustion SPR100 allows continuous monitoring of spark plug insulation integrity for fouling studies and calibration applications.

Particulate & Aerosol Measurement

The DMS500 offers the fastest time response available for real-time measurement of the particulate size spectrum from 5nm to 2500nm at a rate of 10 samples/second. The unrivalled time response, size range and built-in two stage dilution are of the DMS500 make it ideal for applications from diesel emissions development and engine calibration to ambient environmental measurement and pharmaceutical delivery system development.

The DMS50 offers real time measurement of particle size and concentration from 5nm to 560nm. In a compact, rack mounting enclosure with integral sample pump, it is ideal for laboratory applications, integration in engine test cell installations, and for mobile applications (12 V operation possible).

The SCS accessory for the DMS500 offers real time measurement of particle size distribution in a tobacco aerosol, via an actively controlled Constant Volume Sampling System.

Diesel Particulate Generator

The Cambustion DPG is a complete Diesel Particulate Filter loading system, which uses controlled combustion of Diesel fuel to produce a stable soot load rate. The DPG can load and regenerate a DPF without requiring an engine.

Fast Gas Analysers

The HFR400 is a fast hydrocarbon analyser for applications where the sample pressure is not fluctuating, for example in studies of the dispersion of HC tracer gas from point releases or for wind tunnel research.
