Engineering and manufacturing of power bench testers and road simulators is nowadays an important part of Dimsport Technology Group’s core business.

This has been thought to satisfy customers need of Dimsport’s professionalism in such an important division as the equipment one as well, and it was originally managed thanks to partnerships with dynamometer manufacturers, but it soon
required a more structured and organized approach.

That is why, starting from the 90s, the new Equipment Division was created to support the increasing market demand for professional road simulators and power bench testers and to offer a service which could meet quality expectations.

Such a strategic choice has turned out to be successful and appropriate: the first engineered product line was Dynorace for cars and LCVs, then Dynotractor followed (to check the working of the engine through power take-off shaft of tractors), Dynotruck is the latest creation (heavy duty trucks version) and fi nally a specific motorbike version of Dyno is also available.

Power Bench tester Dyno RACE is a computerized diagnostic system for the measurement of the torque and the power performed by a vehicle in running order.

Indispensable to check and analyse the performance parameters of two or four-wheel drive cars & light vehicle (also electronically controlled).

Mechanically designed to suit any loading condition, this dynamometer allows to test vehicles up to 2, 5 ton. per axis, The following measures can be verified simulate and displayed:[img_assist|nid=3117|title=|desc=|link=node|align=right|width=150|height=125]

• MAXIMUM POWER AT THE WHEEL AND RELATED GRAPHIC REPRESENTATION
• POTENCIA MÁXIMA A MOTOR
• MAXIMUM POWER AT THE ENGINE AND RELATED GRAPHIC REPRESENTATION
• TORQUE TO THE WHEEL AND ENGINE AND TREND CHART
• SIMULATION AT CONSTANT SPEED
• SIMULATION ON CONSTANT TRACTION
• MESURE OF THE DISCREPANCY OF SPEEDOMETER
• ROAD SIMULATION

The parameters are measured and corrected through a barometric station integrated in application of the normalization of the curves: DIN 70020, EWG 80/1269, ISO 1585, j1349 SAE, JIS d101001.

DynoRACE power test bench is also equipped with a range of sensor and probe for the acquisition data of analog parameters such as pressure manifold, ambient pressure and temperature, engine oil temperature, exhaust gas temperature, acquisition revolution engine through inductive caliper, oxygen rate (lambda) eventual data digital acquisition through OBDII connection (optional).

The software offers a variety of options to customise the parameters displayed. It allows to elaborate your tests and draw up the results in several, clear reports.

The tests can be saved in a logical structure, and the most significant can be overlapped for comparative purposes, to verify and prove the competence of your professional skills. A special option allows multiple sessions up to eight test.

Reassuring the preservation of the personal integrity as its main goal, the safety equipment allows maximum freedom in its use thanks to an active control on all parts of the dynamometer, as example when handling and varying the wheelbase setting (4WD version) or when locking the rollers and lifting the metal bar in order to move a vehicle in/out, to make operations easier.
