Questions about the emissions calculations API
Posted: Wed Jun 02, 2021 9:34 am
Hi Guys, I did some tests with the PTV emissions API today, and I do have some questions:
1. Which are the fields used to calculate emissions based on HBEFA32?
As far as I check I notice that besides the waypoints, weight and emission standards no other attributes seem to influence the computation. I did set up some data such load, engine details, year of manufacture but none looks to change the computation.
2.Which are the fields used to calculate emissions based on EN16258DEFRA2014?. It looks to me that engine fuel consumption and biofuel ratio are used in calculation, but no other engine properties, neither weight, load, year of manufacturing or emission standard have any part in computation.
3. When we do the EN16258DEFRA2014 computation when shall we use the VEHICLE_SPECIFIC_AVERAGE_FUEL_CONSUMPTION instead of one from FLEET_SPECIFIC_AVERAGE_FUEL_CONSUMPTION, ROUTE_SPECIFIC_AVERAGE_FUEL_CONSUMPTION?
If we want to use one of the FLEET_SPECIFIC_AVERAGE_FUEL_CONSUMPTION, ROUTE_SPECIFIC_AVERAGE_FUEL_CONSUMPTION options, how can we come with specific values such fleet specific or route specific fuel consumption?
Thank you, Romulus Pasca, trucknet.io
