Table 1 - 8-Mode Test Cycle for Variable-Speed Engines

Test segment	Mode number	Engine speed ¹	Observed torque ² (percent of max. observed)	Minimum time in mode (minutes)	Weighting factors
1	1	Rated	100	5.0	0.15
1	2	Rated	75	5.0	0.15
1	3	Rated	50	5.0	0.15
1	4	Rated	10	5.0	0.10
2	5	Int	100	5.0	0.10
2	6	Int	75	5.0	0.10
2	7	Int	50	5.0	0.10
2	8	Idle	0	5.0	0.15

¹ Engine speed (non-idle): ±2 percent of point. Engine speed (idle): Within manufacturer's specifications. Idle speed is specified by the manufacturer.

² Torque (non-idle): Throttle fully open for 100 percent points. Other non-idle points: ±2 percent of engine maximum value. Torque (idle): Throttle fully closed. Load less than 5 percent of peak torque.

Table 2 - 5-Mode Test Cycle for Constant-Speed Engines

Mode number	Engine ¹ Speed	Observed torque ² (percent of max. observed)	Minimum time in mode (minutes)	Weighting factors
1	Rated	100	5.0	0.05
2	Rated	75	5.0	0.25
3	Rated	50	5.0	0.30
4	Rated	25	5.0	0.30
5	Rated	10	5.0	0.10

¹ Engine speed: ±2 percent of point.

² Torque: Throttle fully open for 100 percent point. Other points: ±2 percent of engine maximum value.

Table 3 - 6-Mode Test Cycle for Engines Rated Under 19 kW

Mode number	Engine speed ¹	Observed torque ² (percent of max. observed)	Minimum time in mode (minutes)	Weighting factors
1	Rated	100	5.0	0.09
2	Rated	75	5.0	0.20
3	Rated	50	5.0	0.29
4	Rated	25	5.0	0.30
5	Rated	10	5.0	0.07
6	Idle	0	5.0	0.05

¹ Engine speed (non-idle): ±2 percent of point. Engine speed (idle): Within manufacturer's specifications. Idle speed is specified by the manufacturer.

² Torque (non-idle): Throttle fully open for operation at 100 percent point. Other nonidle points: ±2 percent of engine maximum value. Torque (idle): Throttle fully closed. Load less than 5 percent of peak torque.

Table 4 - 4-Mode Test Cycle for Propulsion Marine Diesel Engines

Mode number	Engine speed ¹ (percent of max. observed)	Observed power ² (percent of max. observed)	Minimum time in mode (minutes)	Weighting factors
1	100	100	5.0	0.20
2	91	75	5.0	0.50
3	80	50	5.0	0.15
4	63	25	5.0	0.15

¹ Engine speed: ±2 percent of point.

² Power: Throttle fully open for operation at 100 percent point. Other points: ±2 percent of engine maximum value.
