Abstract

The analysis of the operation of military vehicles with diesel engines at low temperatures is carried out. A method and a device have been developed to improve the starting of diesel engines by installing a rotary-pulsating apparatus on equipment, directly into the power supply system. Periodic transient hydromechanical processes with the excitation of hydrodynamic, acoustic and impulse cavitation in the working bodies of rotary-pulsating apparatuses are considered, which provide crushing of heavy fractions of hydrocarbon fuel into light ones, which improves the combustion process both in the preheater boiler and in the engine combustion chamber. Mathematical modeling of the fragmentation of a dissolved water drop in the composition of emulsified motor fuel is proposed. The design of a rotary-pulsating apparatus has been developed, which allows to increase the efficiency of starting diesel equipment and reduce the toxicity of exhaust gases. The use of a rotary-pulsating apparatus allows to reduce the start-up time of diesel equipment, as well as to reduce the toxicity of exhaust gases.
