System and method of predicting pollutant emissions of a vehicle with simultaneous chemical kinetics and emissions calculations

A system of predicting emissions of pollutants from a vehicle equipped with an engine, including processors for determining the emissions of pollutants, comprising:

• a first group of processors for carrying out calculations of chemical kinetics allowing determination of amounts of chemical compounds present in a chemical reaction in the engine according to a reaction and to thermodynamic conditions of the engine;
• a second group of processors for carrying out calculations of emissions of pollutants allowing determination of the emissions of pollutants from the calculated amounts of the chemical compounds;
• wherein
• the calculations by the first and second groups of processors are carried out simultaneously;
• and
• the first group of processors comprises a global supervisor processor and at least one cluster of processors and the global supervisor storing data required for the calculations and distributing the calculations of chemical kinetics among available processors of the at least one cluster of processors.
