Vehicle emissions testing

Vehicle emissions testing

Ricardo vehicle test facilities support durability, noise, emissions and performance development activities across vehicle types ranging from small scooters, to performance motorcycles, passenger cars and light commercial vehicles, equipped with both conventionally fuelled or hybrid electric powertrains. These facilities are at the disposal of customers for tasks ranging from product homologation to research into the benefits of new technologies and innovations, and provide a cost effective solution tailored to individual needs.

Vehicle Emissions Research Centre (VERC)

Ricardo’s £10 million Vehicle Emissions Research Centre (VERC) sets a new standard in vehicle-testing technology, providing a w orld-class facility that will enable the development of next-generation clean, low carbon vehicles. The VERC was designed from the outset to accommodate the development requirements of the next generation of more environmentally friendly and fuel-efficient road-going vehicles.

  • The VERC has been configured to allow for maximum flexibility and efficiency of operation
  • First facility in UK to be officially certified for WLTP
  • 300kW / 250kph 4WD chassis dynamometer suitable for road-load simulation of all power-train platforms and HEV configurations
  • Temperature range from -30°C to +55°C with humidity control
  • Large soak space to accommodate around the clock testing
  • Integrated cold boxes with independent climate control
  • Climatically controlled transit zone for transport of vehicles from cold box to test cell for comprehensive legal compliance
  • Emissions measurement systems capable of supporting engineering projects to the regulatory standards applied in all parts of the world, up to and including the very highest Euro 6/7 and US SULEV standards
  • Unique three tunnel CVS system utilising next generation Horiba MEXA-ONE exhaust gas sampling systems for highly accurate measurement of emissions for both high and low emitting vehicles eliminating the risk of cross-contamination
  • In addition to Horiba’s standard commissioning protocols, a Low Emissions Vehicle Simulator (LEVS) has been used to quantify base systematic accuracy and repeatability across the three dilution tunnels and across multiple CVS flow rates

Unregulated emissions testing

In addition to the currently regulated gaseous emissions and particulates, vehicles and engines emit other materials and compounds that are of interest in terms of aftertreament system engineering as well as for environmental and health reasons with relevance to potential future regulatory control. Ricardo is actively involved in the measurement of unregulated emissions species, both on-line in real-time and off-line in laboratory-based analyses. New instrumentation and novel applications of existing equipment is continuously being researched by Ricardo to address the species of current interest, as is fuel, lubricant, additive, combustion technology and catalyst influences and how these give rise to new components of interest and potential concerns.

Particle measurement capabilities

  • Ricardo had a leading role in development of PMP mass and number legislation for Euro 5+/ Euro 6 and now Euro VI
  • Euro 5/6 mass and number capabilities in place
  • Real-time particle sizing
  • Real-time PM estimate from tailpipe and from pre-DPF locations
  • Oil separator size-specific performance
  • Fuel, lubricant and catalysis effects on particle size, number and mass
  • Simultaneous pre- and post catalyst particle size, number and mass estimate measurements for efficiency determinations
  • Fourier transform infra red (FTIR) and mass spectroscopy:
  • Analysing catalyst performance in real time in terms of mass and volume concentration
  • Developing robust calibrations to minimise undesirable emissions, such as NH3 slip from SCR systems and H2S emissions during regeneration of LNT systems
  • Dual FTIR systems for real time emissions reduction diagnosis of catalytic systems.
