AVL DynoTest Engine Dynamometer
The AVL DynoTest is a chassis dynamometer used to measure torque, power output, and fuel efficiency of internal combustion engines in vehicles during performance testing. It falls under HTS 9031.80.80.70 as specialized equipment for testing engine characteristics like emissions and drivability, not covered elsewhere in Chapter 90. This classification applies to diagnostic machines for automotive engine testing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for gas/emissions analysis without power measurement
Focus on gas analysis shifts to Chapter 90 heading for chemical/measuring machines.
If classified as gas turbine testing apparatus
Specific engine type like turbines may fall under Chapter 84 machinery headings.
If for oscilloscopes used in engine diagnostics
Electronic measuring instruments for voltage/waveforms classify in heading 9030.
