Emissions



Our Emissions Chassis Dynamometer provides an extremely accurate, repeatable and responsive electrical inertia simulation vehicle test system. The chassis dynamometer utilises an AC motor centrally mounted between the rolls that provides a compact, low maintenance design. All components are mounted on a single substantial steel underframe providing rigidity, low vibration and ease of installation.
The chassis dynamometer control system includes several automated routines to test and validate all the main performance criteria.
Emission chassis dynamometer solutions are also available for truck and motorcycle applications
Main Features of our Emissions Chassis dynamometers:
- 48″ roll with centre-mounted AC motor
- Compliant with EPA, EURO III, IV and V legislative emissions test requirements
- High accuracy and repeatability with fast response inertia simulation
- Clean power IGBT AC drive technology
- Thermally stabilized load measurement system
- Twin encoders for increased accuracy
- Real time control processor and separate Graphical User interface PC using distributed I/O hardware platform
- Automated dynamometer performance testing routines
- Above floor loadcell calibration
- 4×2 and 4×4 configurations
- 4×4 independent systems for Hybrid Vehicle testing
- Robust design for long and trouble-free operational life
- Low maintenance and lifecycle costs
- A Robot driver is also available to complement this Chassis dynamometer to assist with repeatable results.
