The first steps to create domestic neutralizers of exhaust gases for automobiles and tractors

The article describes the history of the development and creation of the first domestic neutralizers of exhaust gases of internal combustion engines, which began with testing and research of foreign neutralizers. Sequential stages of design, study and testing of domestic converters for gasoline and diesel engines are considered. There are described the following processes: the process of developing methods for testing engines for toxicity and the process of creating estimated indicators and developing normative and technical documents in the field of toxicity of engines and vehicles.
