US: Heavy-duty: CTA


The CTA (Chicago Transit Authority) test cycle is typically used for dynamometer aging of engines, engine components, or emission control devices.


The graph and linked torque/speed data file represent a 5 minute trace, which can be modified to suit the testing laboratory. The cycle is usually run continuously, multiple times in succession, for a period of tens or hundreds of hours.
