Engine and vehicle test facilities

Vehicle Simulation System

Cambustion were amongst the first in the industry to simulate a full vehicle drivecycle on a transient engine dynamometer. Test-bed control software developed in-house enables a wide range of tests to be conducted:

Drivecycle simulation for emission testing (NEDC, FTP, etc). The system has been correlated with real vehicle–based tests on a chassis roll.
Steady–state or speed/load scheduled tests for basic engine calibration and mapping, and allowing the development and use of automated mapping techniques.
Capability to simulate both manual and automatic transmissions.
Integration of control system tools (such as Matlab / Simulink and ASCET-SD) with engine control software enables rapid prototyping and development of ECU control software which is fully vehicle transferable.

Transient Dynamometers

Engine fitted to dynamometer and instrumented for emissions measurement

Cambustion currently has five transient test–beds with varying specifications:

Power up to 220kW
Torque up to 700Nm
Speed up to 9000 RPM
Ambient temperature down to -20°C

Cambustion has developed an engine pallet system which allows the engines to be mounted and tested before installation on the test–bed minimizing down–time. The pallet system includes a forced cooling facility in order to maximize the test repeat rate.

Chassis Dynamometer

Vehicle on chassis dynamometer for emissions development

100 kW 48 inch emissions chassis roll dynamometer with robot driver and integrated pre–conditioning facility.

Diesel Particulate Generator

Instrumentation

Gas Analysers (gasoline & diesel compatible)

Cambustion fast analysers are ideal for identifying and resolving the emission issues associated with a variety of transients such as cold start, gear shifts, DPF regeneration and NO_x purges. The following can be available to each Cambustion test-bed:

Fast HC, NO (and optional NO_x converter), and CO & CO₂ analysers.
Horiba 7000 series analysers for THC, CH₄, CO, CO₂, O₂, NO_x, and EGR (CO₂)
Horiba UEGO lambda sensors
MKS FTIR analyser

Particulates

Gravimetric filter paper measurements (2 phases per cycle)
Cambustion DMS500 Fast Particulate Analyzer (response time < 200ms)
AVL opacimeter

Combustion Analysis

Wide range of in-cylinder pressure sensors
Combustion analysis for IMEP, burn rates and knock detection.

Pressure and Temperature

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