40 CFR Appendix II to Part 1054, Duty Cycles for Laboratory Testing
(a) Test handheld engines with the following steady-state duty cycle:
|G3 mode No.||Engine speed a||Torque
(b) Test nonhandheld engines with one of the following steady-state duty cycles:
(1) The following duty cycle applies for discrete-mode testing:
|G2 mode No. a||Torque
(2) The following duty cycle applies for ramped-modal testing:
|RMC mode a||Time in mode
|Torque (percent) b c|
* Linear transition.
b Advance from one mode to the next within a 20-second transition phase. During the transition phase, command a linear progression from the torque setting of the current mode to the torque setting of the next mode.
c The percent torque is relative to the value established for full-load torque, as described in § 1054.505.
