Dyno Race 4WD DF4IS - DF4FS
1
Eddy current brake
2
Knurled roller surface to improve traction
3
Lift & lock system – easy positioning
4
Electric engine for wheelbase adjustment
5
Steel plates for easy sliding
Again the compact size of this device, the user-friendly logic and the versatility of its software, as well as the accuracy of assessments make Dynorace the ideal machine for servicing both workshops willing to integrate a diagnostic graph and tuning/developing centers involved in motorsport.
The possibility to recreate working defects/problems occurred on the road and the repeatability of the tests performed (which involves the stability of the measured data) have always been pursued as primary target in the development of the device. The consequence of this approach is the continuous improvement of our range of dynamometers in the past few years which also means the highest trustworthiness of the results acquired during the tests.
The use of eddy current brakes (theoretical braking power over 500 Hp for each axle) allows dynamic tests like:
- Test of duration
- Regenerative procedure of diesel particulate filter
- Test of fuel consumption
- Research and development on vehicles
- Test of vehicle’s working and quality
Moreover, all dynamometers of the DYNORACE line are mechanically engineered to support max 2.500 kg per axle and are equipped with a blocking and lifting system of the rollers in order to make this operation easier and again, safer.
Finally, Dynorace line is accessoried by items that can better support or complete its tests. The electric and electronic part managing the working of the dyno is common to all versions (a panel next to the dynamometer), while the software managing is carried out through a Personal Computer.
The data acquired can be integrated by additional parameters made available by the analog acquisition system and a kit to assess the wide band oxygen value.
Lastly, the centrifugal fan is important to avoid the increase of temperature of the intake air and therefore overheating of the engine. This fan can be connected to an inverter to link the air speed to the one of the vehicle being tested, so to better simulate road conditions.
