Dyno ASM is the dedicated dynamometer for under load emission measurements in accordance with BAR 97 Specification, ruling the standards required for the evaluation of vehicle emissions with particular reference to ASM 5015/2525. Dyno ASM allows to perform a number of emission measurements in different load conditions, such as constant or variable load in the simulation of driving cycles; a wider range of settings are available for further measurements on all kinds of passenger cars.

The DF2ASM can be installed either above floor or embedded and supports both petrol and diesel vehicles.
