Scientific and technical strategy for ensuring the safe use of special-purpose machines in emergency situations

Based on the analysis of the technical condition of fire engine engines, a strategy is proposed to ensure the sanitary and hygienic safety of their use in the field of operation. The concept is based on the use of new knowledge about the nature of the formation of problematic NO and PM2.5 directly in cylinders, as well as the introduction of original methods and equipment for the technical diagnosis of fuel equipment failures, emulsification of fuel with water and replacement of the standard noise suppressor with a device that combines the functions of neutralization and noise suppression of spent exhaust gases. The use of original methods on the engine in a complex made it possible to increase its safety by 2 environmental classes for 13 regime load cycles.
