Exhaust aftertreatment testing
Cambustion instrumentation for exhaust aftertreatment testing
Particulate filter testing system
The Cambustion DPG is the standalone system for the testing of Diesel and Gasoline Particulate Filters. Supporting a variety of loading rates, regeneration, thermal shock tests, ash loading and filter efficiency measurements, the DPG offers a highly effective solution for a wide range of DPF and GPF projects.

CLD500 two channel analyser
Using a chemi-luminescence detector, Cambustion fast NOₓ analysers offer NO&NO₂ measurements at up to 500Hz. This is fast enough to observe NOₓ from individual firing cycles (which can vary substantially) and observe the consequent performance of NOₓ aftertreatment.

Automotive Twin Channel CO & CO₂ analyser
Using a non-dispersive infra-red detector, Cambustion fast NDIR analysers offer CO&CO₂ measurements at up to 125Hz. This enables transient measurement of true combustion lambda (unaffected by excess hydrocarbons), EGR rate and more...

HFR500 two channel analyser
Introduced in 1998, the HFR500 is a two channel analyser capable of measuring engine-out and tailpipe THC simultaneously for cold start and catalyst heating strategy optimisation. It is also configurable for sub-zero testing and also for sampling in individual exhaust ports at turbo pressures to study cycle-by-cycle HC emissions; a technique often used to study the gas exchange processes in VVT and 2-stroke combustion systems. The measurement of methane slip on gas or diesel/gas engines has been performed and via use of a “sampling spark plug”, sampling from inside the operating combustion chamber is also possible.
The HFR500 is available with support for AK protocol.

Fast engine particulate analyser
Updated to support development for possible Euro 7 standards, while offering supporting insights through measurement of particle size distribution to understand combustion processes, the DMS500 has long established itself as the particle instrument of choice for engine research, development and calibration.
