SYSTEM AND METHOD FOR PREDICTING THE EMISSIONS OF POLLUTANTS OF A VEHICLE WITH SIMULTANEOUS CALCULATIONS OF CHEMICAL KINETICS AND EMISSIONS

摘要

The invention relates to a system for predicting the pollutant emissions of a vehicle equipped with an engine, comprising a plurality of processors (3) allocated for the determination of pollutant emissions, comprising: a first group of processors (1) dedicated to carrying out calculations of chemical kinetics, said calculations of chemical kinetics making it possible to determine the quantities of the chemical compounds present in a chemical reaction in said engine as a function of a given reaction scheme and thermodynamic conditions of said engine; . a second group of processors (2) dedicated to carrying out calculations of pollutant emissions, said calculations making it possible to determine the pollutant emissions from the quantities of the chemical compounds calculated, the executions of the calculations by said two groups of processors (1 2) being simultaneous. The first group of processors (1) consists of a global supervisor processor (4) and at least one cluster of processors (5), said supervisor (4) allowing the storage of data necessary for the calculations and to distribute said data calculations on said clusters (5) of available processors.
