Applus+ IDIADA 4WD Center Mounted Chassis Dynamometer

TeSys implemented the supply of emission dyno grade to one of the biggest homologation research & development institutes in Spain, Tarraogna

TeSys is proud to announce the successful delivery and completion of an emission-grade chassis dynamometer project for Applus+ IDIADA in Tarragona, Spain, one of Europe’s leading homologation and R&D laboratories. Engineered to comply with CFR, WLTP/GTR15, and EPA 97 requirements, this project reinforces TeSys’ technical expertise and reliability in providing advanced vehicle testing solutions for international emissions certification and automotive development. - 4WD Center Mounted Chassis Dynamometer (Emission grade)

- Automatic Roller Cover

- Horbia StarsVET (Exhaust analyzer) communication interface

- S.Bleyer Vehicle Fixation

- Customized automatic test cycles

1

Global quality standardization of chassis dyno and CFR/GTR15 compliance

EPA CFR1066/GTR15: CFR1066.260- Paraistic Friction Compensation data at min/base/max inertia simulation range

Achieved result: All data points are less than 1N

The measured data provides clear evidence of the mechanical system’s superior alignment and balancing quality, confirming that mechanical friction losses have been minimized to near-negligible levels. This achievement highlights TeSys’ advanced mechanical design, precision assembly, and rigorous validation capabilities, ensuring stable, accurate, and highly efficient dynamometer performance.

Dyno quality and performance proof

EPA CFR1066/GTR15: CFR1066.220 - Dynamometer Measurement Systems that Require Linearity Verifications
CFR1066.270 - Unloaded coastdown 4WD/2WD mode at min/base/max load

The measured results serve as a key indicator of the dynamometer’s dynamic performance and engineering quality. TeSys chassis dynamometers demonstrate remarkably low force error across both low-speed and high-speed operating conditions, validating the system’s outstanding measurement precision, dynamic response, and reliability. This data provides compelling evidence of the decisive performance and quality advantages of TeSys chassis dynamometer technology.

*By demonstrating repeatable results over a minimum of three repeated test cycles, TeSys provides objective evidence of system stability, measurement consistency, and engineering reliability. This outstanding repeatability reinforces the proven quality and performance confidence of TeSys chassis dynamometer solutions.

Operational safety assurance with the automatic roller cover design & vehicle centralizing device

For advanced operator protection

TeSys chassis dynamometers are equipped with an automatic roller cover system that actively monitors tire-edge clearance and maintains a controlled safety distance throughout testing. Working together with the centralizing device, this safety-oriented design minimizes exposure to rotating components and supports a secure, controlled, and operator-friendly test environment.
