Abstract:Transport is a major source of the particle pollution (PM). Combustion engine particulate emissions have the potential cause adverse health effects. These effects include cancer and other pulmonary and cardiovascular diseases. A substantial proportion of the number of particles, but not the mass, is ultrafine. For example -one million particles of 100 nanometers size with a unit density of 1 g/cm3 have a mass of approximately 0.0005 g. The paper includes research results of mass and number concentration of nan… Show more
“…The connections between the chemical composition and toxicity of particles tend to be stronger for small and ultrafine fractions [1]. The issues of the distribution of particulate matter by fractions during the combustion of diesel fuel were also considered in [7,8]. Emissions from a diesel engine depend on the nature of the interaction of fuel and air in the engine cylinder.…”
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.
