2WD CAR AND LCV DYNAMOMETER

Power bench tester range identified as „DF2 line”.

Available in two different versions:

  • Inertial (code DF2IS), equipped with flywheel mass;
  • Braked (code DF2FS), equipped with eddy current brake.

If supplied with flywheel mass, DYNORACE can be used to record and analyse the vehicle performance like torque, power, speed and engine rpm. Furthermore, the management software allows to perform accurate tests and assessments on the working precision of onboard tools like speedometer/tachometer.

The eddy current braked version of DYNORACE offers additional functions and plotters to enhance the range of tests supported. The exploitation of the load simulator programs determines the ideal basis for vehicle diagnostic and testing under load conditions, to verify and recreate problems occurred as well as improve the engine efficiency (motorsport purposes).

The strategic choice of a double-roller frame per wheel clearly highlights our approach: maximum safety conditions during the tests. Each wheel is positioned between two rollers to fix the vehicle and secure the working operations (the alternative choice of a singleroller frame per wheel could determine a dangerous „floating” effect of the vehicle and consequent higher risks during the tests).

The rollers are mounted on high performance bearings conceived for aeronautic purposes.

DYNORACE allows to achieve tests on top performance vehicles (also in constant traction) up to 400 KW per axle and 320 Km/h speed.

The measurement data are collected and standardized through a barometric station integrated in accordance with the following regulations:

  • DIN 70020
  • EWG 80/1269
  • ISO 1585
  • SAE J1349
  • JIS D101001

The exploitation of the load simulator programs supported by the management software of DYNORACE allows to acquire and display measurement data such as:

  • Maximum power at the wheel, graphic representation and numeric tables of the measurement data collected during tests performed;
  • Maximum power at the engine (nominal), graphic representation and numeric tables of the measurement data collected during tests performed;
  • Torque at the wheel, nominal torque at the engine, graphic representation and numeric tables of the measurement data collected during tests performed;
  • Load simulation at constant rpm;
  • Load simulation at constant speed;
  • Load simulation at constant traction condition;
  • Road simulator according to CX and realistic variable load conditions;
  • Measurement of the discrepancy of the speedometer/tachometer.
