Credits = (Standard -- FEL) x Sales x Power x EDP x Load Factor
Where:
Standard = the current and applicable small off-road engine HC+NOx (NMHC+NOx), CO, or Particulate Matter emission standard as determined in Section 2403.
FEL = the family emission limit for the engine family in grams per brake-horsepower hour or g/kW-hr as applicable.
Sales = eligible sales as defined in section 2401. Annual sales projections are used to project credit availability for initial certification. Actual sales volume is used in determining actual credits for end-of-year compliance determination.
Power = the sales weighted maximum modal power, in horsepower or kilowatts as applicable. This is determined by multiplying the maximum modal power of each configuration within the family by its eligible sales, summing across all configurations and dividing by the eligible sales of the entire family. Manufacturers may use an alternative if approved by the Executive Officer (for example, maximum modal power of the test engine).
EDP = the Emissions Durability Period for which the engine family was certified in hours.
Load Factor = For Test Cycle A and Test Cycle B, the Load Factor = 47% (i.e., 0.47).
For Test Cycle C, the Load Factor = 85% (i.e.,0.85). For approved alternate test procedures, the load factor must be calculated according to the following formula:
Where:
%MTT modei = percent of the maximum torque for mode i
%MTS modei = percent of the maximum engine rotational speed for mode i
WF modei = the weighting factor for mode i
