Reasons for Forming Particulate Matter in Exhaust Gases of Internal Combustion Engines

Measuring the amount of particles in the exhaust gas plays an important role in the automotive sector, it begins more important with the introduction of Euro standards which limit the amount of harmful substances entered the air together with the exhaust gases of an automobile engine. Exhaust gas contact is associated with adverse health effects on the respiratory system, cardiovascular system, and increased morbidity and mortality. They are a heterogeneous mixture of various gaseous substances with various chemical and physical properties, consisting of products of complete and incomplete combustion of fuel, excess air, aerosols and various trace elements. The main standardized toxic components of diesel engine exhaust gases are carbon, nitrogen and hydrocarbon oxides, carbon black. The article discusses the process of formation of particulate matter in the exhaust gases of internal combustion engines. An analysis of the reasons of particulate matter in exhaust gases is made. By analyzing the exhaust gases and testing the degree of deviation of actual combustion results from the desired, various problems can be resolved. Throughout the right approach to the analysis of the composition of the exhaust gases, a conclusion about the efficiency of the internal combustion engine can be made.
