Simulation of atmospheric PAH emissions from diesel engines.

摘要: Simulation of atmospheric PAH emissions in a typical European passenger car diesel engine at steady conditions or under certification cycle is made using in-house software. It based on neural fitting experimental data from eight different fuels tested five operating (reproducing modes the transient urban/extraurban cycle). The software allows determination as function fuel composition parameters (aromatic content, cetane index, gross heat power, nitrogen and sulphur content) operation (torque speed). mathematical model reproduces with maximum error 20%. This tool very useful, since changes can be without cost trend modifications immediately obvious.
