Vehicle Exhaust Emissions Laboratory


We have played an influential role in exhaust emissions development and were the first truly independent emissions test laboratory.


We now have ambient emissions capability in our Vehicle Exhaust Emissions Lab (VEEL) and climatic emissions capability in one of our Climatic Wind Tunnels (CWTone). Both facilities use state of the art HORIBA emissions analysis systems and are Vehicle Certification Agency (VCA) approved for legislative tailpipe emissions testing to European standards. We are also able to test to other worldwide standards including US Federal. In addition, in our ambient facility, we carry out real-time analysis of emissions to assist with emissions development for optimal engine management calibration.

We use our expertise and facilities to assist our customers in developing their vehicles to meet and exceed the ever-tighter exhaust emissions legislation and fuel economy (CO2) targets driven by government requirements and public demand for cleaner, more fuel-efficient vehicles. In response, we introduced the latest HORIBA particle number analysis system to meet the requirements of forthcoming legislation in response to health concerns over inhalation of particulate matter.

Our ambient facility (VEEL) comprises a chassis dynamometer with speed tracking fan, HORIBA 7000 series emissions system for gasoline, diesel and alternative fuels, large soak area, particulate weighing clean room and temperature/humidity control. Our climatic facility (CWTone) comprises a full climatic wind tunnel, including solar simulation and 4WD chassis dynamometer, with the addition of HORIBA 7000 series emissions system for gasoline and alternative fuels.

Between these two facilities, we have the capability to carry out dilute tailpipe emissions analysis, raw emissions analysis, mass particulates, particle number analysis, catalyst efficiency, fuel consumption, European and US Federal cold start (-7ºC) emissions, US Federal SFTP US06 and SC03 and ambient/hot/cold emissions development.
