ADAPTIVELY CONTROLLED FUEL PREPARATION AND SUPPLY SYSTEM OF A VEHICLE Russian patent published in 2023 - IPC F02D19/12 F02M25/00 F02M37/00 F02D41/00 

FIELD: engine building.

SUBSTANCE: adaptive-controlled system for preparing and supplying fuel to a vehicle engine is proposed, comprising container 1 for diesel fuel, container 12 with an additive, fuel priming pump 11, water filter 2, dispersing device 4, two electromagnetic valves 3, 9, automatic control device 8 installed on high pressure fuel pump 7. Sensor 5 for determining the percentage of additive in fuel, fuel quality control sensor 14 and fuel temperature sensor 15 are installed in the fuel tubes, the outputs of which are connected to the inputs of electronic evaluation unit 16. The output of fuel priming pump 11 is connected to the input to coarse filter 10, the output of which is connected to the input of solenoid valve 9. The outputs of high-pressure fuel pump 7 are connected to the inputs of injectors 13. At the bottom inside container 1 with diesel fuel and container 12 with an additive, holes are made into which fuel level sensors 17 are installed, the outputs of which are connected to the input of electronic evaluation unit 16.

EFFECT: increase in the information content and accuracy of data on the quality of fuel with an additive in real time with the possibility of analysing the mechanism of their occurrence and correcting the methodology for modelling the operation of internal combustion engines with imitation of various malfunctions and emergencies, as well as visual demonstration of the operation of electronic control units of internal combustion engines, which allows for diagnostic, research, development and laboratory tests.
