Test Facilities

Introduction to Test Facilities

Our extensive test facilities include a chassis dynamometer and eight transient engine dynamometer cells, all equipped with constant volume sampling (CVS) tunnels for emissions monitoring.

We have experience testing against many different emissions cycles, including NEDC (Euro cycle), FTP transient cycle, US06, JC08, Japanese 10 and 15 mode cycles and the Non Road Transient Cycle (NRTC).

All of our highly qualified engineers are directly involved in operation of the test facilities, promoting a hands-on and productive approach to solving technical challenges. Extensive in-house development of test system hardware and software means that we are able to offer an innovative, flexible approach which is essential for meeting new emissions challenges.

Transient Engine Dynamometers

Cambustion currently has eight transient test–beds with varying specifications.

Our rapid cooldown facility allows improved testing efficiency, while the pallet system allows the engine to be mounted and tested before installation in the test cell for reduced downtime.


  • Power up to 460kW
  • Torque up to 1,300Nm
  • Speed up to 9000RPM
  • CVS tunnels for emissions
  • Ambient temperature down to -20°C

Chassis Dynamometer

Cambustion’s 100kW 48inch emissions chassis roll dynamometer with robot driver and integrated pre–conditioning facility allows testing of complete vehicles against a range of transient drive cycles.

Rapid cool down of vehicles allows improved testing throughput.

Pressure and Temperature

  • Pressure: 4 per test-bed (standard)
  • Temperature: 8, 16 or 32 channels per test-bed. Higher channel counts are possible

DPF Testing System

Cambustion offer additional DPF testing and development services using the non-engine Cambustion DPF Testing System.

DPF Testing System

  • DPF loading at up to 20g/hr
  • Filter efficiency measurement
  • DPF regeneration
  • Advanced tests- e.g. Soot Mass Limit
  • Cold flow testing
  • Diesel fuelled
