I am developing a vehicle simulation library which includes calculations on fuel economy, using data obtained from specific fuel consumption maps. Although plenty of maps are publicly available (in image form) on the internet they tend to be:
- too old, often from engines with emissions and power outputs which do not represent modern designs/calibrations
- not from identified and verified sources, with no information about intake temp / ancillaries etc..
- poor resolution hampering digitisation
I am looking for a small handful of up-to-date maps, preferably from a proper source such as a published journal paper. Being in Europe, of particular interest are small common-rail turbo diesels (Euro 5/6) and modern downsized turbo-direct-injection petrols (gasoline). A heavy duty diesel map or two would be useful too. Tier2bin5 engines would also be acceptable.
Does anyone know of where I should be looking? I don't have free access to journals, but would be willing to buy a couple of specific papers if they have the information I need. Any information on motored friction (FMEP) vs speed would also be very useful if anyone has any ideas. This is necessary for motored torque and no-load fueling estimations.
