Correlation investigations into pollutant emission and the operational states of compression-ignition engines in dynamic tests

This study investigates the correlation dependences between pollutant emission intensity and the engine operational states determining these properties, in various conditions, both in relation to measurements of engine operational states and their dynamic nature. The research was carried out in a variety of dynamic tests. Investigations into the correlations of processes occurring in combustion engines make it possible to assess the impact of one process on another and the relationship between the various processes. In general, it was found that similar dependencies occur for carbon monoxide and hydrocarbons, but were often substantially different for nitrogen oxides.
