Using ARB’s chassis dynamometer in Los Angeles, ARB could generate these maps. Alternatively, ARB could hire a consultant to develop the test cycles. In our opinion, the lack of a proven test cycle is not a sufficient reason to have unequal standards for chassis and engine dynamometer testing…

Correction algorithms for WLTP chassis dynamometer and coast-down testing: final report of EU-COM study. The Commission services want to make the draft final report on the correction algorithms for WLTP chassis dynamometer and coast-down testing available to the WLTP informal working group. Albeit this report is not finally approved, it gives ...

Pending dynamometer testing and verification of inertial loads/vibrations, mounting may be modified to accommodate stiffness and strength requirements. In that case, alternative options such as mounting the turbocharger assembly to the chassis may be presented, as well as a combination of support from the roll hoop and chassis.

As a result, the two candidate procedures (random cycle on a chassis dynamometer and on-road testing with PEMS) have to be developed and the ‘regulatory implementation’ will be finalized at a later stage. To address the above targets, the objectives of the RDE-LDV working group are revised as …

Chassis Dynamometer Testing vs. Track Testing. ATC recognise concerns regarding test variability and support reasonable efforts to minimise such but are, however, also cognisant of the need for a practical test protocol. ATC believe that restricting the protocol to operation only on chassis dynamometers, as was discussed at the meeting, will ...
