Factors > Hot

This form provides a general view of the Hot Stabilised Emission Factors under four different columns (Urban Off Peak, Urban Peak, Rural, and Highway). These emission factors correspond to vehicle emissions when the engine and exhaust components have reached their nominal operation temperature. Vehicles that have zero Speed values in the Activity Data>Circulation Data form will not be shown or their factors will be zero. One can view the factors for each pollutant through the Pollutant drop-down list and for each sector through the Sector drop-down list. Included in the pollutant list is also the fuel consumption for stabilised engine temperature (FC).

When one wishes to introduce own emission factors and not use the values proposed by the software, he/she can simply replace the proposed value by typing in the respective cell. The value will be displayed red indicating an updated value. If the user wishes to finalise the update he/she must click on the "Apply" button. The value will be displayed as black in an orange cell indicating a user value. In order to restore this emission factor to the COPERT calculated value the user needs to right click on the value he wishes to restore and select "Set default values" from the proposed menu. Alternatively he/she can select all values in the form by pressing "Ctrl + a" and then by right clicking restoring all to the default values.
