calcEF_NOx.Rd
Calculates the appropriate nitrogen oxide (NOx) emission factor (g/kWh) for the given parameters.
calcEF_NOx(engineType, location, tier, main_aux_boiler = "main")
engineType | Engine type (vector of strings) (see
|
---|---|
location | Location of vessel (vector of strings). Valid values are:
|
tier | NOx engine tier (vector of strings) (see
|
main_aux_boiler | Is this calculation for a propulsive (main), auxiliary (aux), or boiler engine? Options:
|
EF_NOx
(g/kWh) (vector of numericals)
Location is important for determining the fuel being used, as type of fuel typically used varies by location.
For more information about calculating NOx emission factors, see Section 3.5.1 of the Port Emissions Inventory Guidance.
