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(percent) b Weighting factors
a Test engines at the specified speeds as described in § 1054.505.
b Test engines at 100 percent torque by setting operator demand to maximum. Control torque during idle at its warm idle speed as described in 40 CFR 1065.510.
1 Rated speed 100 0.85
2 Warm idle 0 0.15
(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(percent) b Weighting factors
a Control engine speed as described in § 1054.505. Control engine speed for Mode 6 as described in § 1054.505(c) for idle operation.
b The percent torque is relative to the value established for full-load torque, as described in § 1054.505.

2 75 0.2
3 50 0.29
4 25 0.3
5 10 0.07
6 0 0.05
(2) The following duty cycle applies for ramped-modal testing:
RMC mode a Time in mode(seconds) Torque (percent) b, c
* Linear transition.
a Control engine speed as described in § 1054.505. Control engine speed for Mode 6 as described in § 1054.505(c) for idle operation.
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.
