Performance testing was done on a 1219 m (48 in) roll diameter chassis dynamometer to validate its compliance with EPA specifications. The testing procedure and results are presented. Tests include time, speed, acceleration and torque calibration verification, load control response time, parasitic loss compensation and stability, base mechanical inertia verification, road load curve simulation and repeatability, automatic road coastdown coefficient matching, and overall simulation accuracy during severe acceleration and emission test cycles. These testing methods provide an objective and comprehensive evaluation of chassis roll dynamometer performance.
