The article describes an automated system for the production of water-diesel emulsions that combines thermal jet dosing and membrane emulsification. The main objective of the study is to develop a control scheme for the module of drip injection of the dispersed aqueous phase into the continuous fuel phase. The proposed system includes a dosing unit, a membrane emulsification unit, a control module, a power supply system, and tanks with fuel and water. The principle of operation of the thermal jet module is described in detail, which produces droplets by pulsed heating of the liquid until it is ejected through the micronozzles. The principle of controlling the module based on a microcontroller, which consists in generating short pulses of the corresponding voltage, as well as a scheme for stabilizing the power supply and generating control signals, is presented. The proposed system allows for precise dosing of the dispersed phase, taking into account the volume of the droplet formed by each control pulse. The created emulsion is fed to the membrane module, where its structure is refined by pressing through the pores. The principle of membrane emulsification and the peculiarities of the hydraulic timing of the system are described. The proposed approach ensures an accurate ratio of the dispersed and continuous phases of the emulsion, the formation of droplets of the dispersed phase of the desired size, and the functional interaction of all components in real time.
