The article considers the application of laser light sources in exhaust gas mixture analyzers of automotive internal combustion engines. The authors show functional diagram of the installation where it is possible to carry out experiments on testing and selection of lasers for use in analyzers of gases contaminated by impurities. The possibility of using the coordinate photodetectors of FDK-124 type in analyzers of gas, polluted by microparticles, is presented as well.

The paper considers a model of combustion powdered energy-accumulating substances (EAS) in a cylindrical combustion chamber. This camera can be considered as a prechamber of the hydrogen reactor for transport and stationary power plants based on gas turbine engines. For calculations of combustion of powdered EAS in the flow of superheated steam a program is developed. Distribution of the temperature in the chamber axis at different values of the coefficient of oxidant excess (water vapor). The authors determined the size of the depth of the flame front at the given conditions of the combustion chamber with energy-accumulating substances.
