Calculates the appropriate hydrocarbon (HC) emission factor (g/kWh) for the given parameters.

calcEF_HC(engineType, main_aux_boiler = "main")

Arguments

engineType

Engine type (vector of strings) (see calcEngineType). Valid values are:

  • "SSD"

  • "MSD"

  • "MSD-ED"

  • "GT"

  • "GT-ED"

  • "ST"

  • "LNG"

  • "HSD" (auxiliary only)

  • "Boiler" (boiler only)

main_aux_boiler

Is this calculation for a propulsive (main), auxiliary (aux), or boiler engine? Options:

  • "main" (Default)

  • "aux"

  • "boiler"

Value

EF_HC (g/kWh) (vector of numericals)

Details

For more information about calculating HC emission factors, see Section 3.5.4 of the Port Emissions Inventory Guidance.
