DIAGNOSTICS OF MOBILE FIRE PROTECTION EQUIPMENT USING A DYNAMIC ENGINE LOADING ROBOT-MANIPULATOR

摘要

The article substantiates the advantages of robotization of the dynamic mode of their loading in the standard procedure of «free acceleration» based on the analysis of the state and development of the methodology of instrumental diagnostics in the operating conditions of fire trucks with diesel piston engines. The advantages are revealed by bench tests of the fuel equipment of a full-size automotive and tractor diesel engine by changing the installation adjustments of the fuel supply within the values identified in real operation. The studies have established that the use of a robotic manipulator allows, along with ensuring a high degree of reproducibility of the diagnostic procedure over time, to establish clearly expressed patterns of change in the diagnostic parameters of the fuel supply and, directly, through the work process, associated with them – optical density (absorption coefficient) and gas composition of exhaust gases. The proposed methodological approach to diagnostics has been positively tested on diesel engines of fire trucks of different designs in real conditions of use.
