DUAL-FUEL FEEDING SYSTEM OF DIESEL VEHICLE Russian patent published in 2019 - IPC F02M43/00 F02D19/08 

FIELD: engines and pumps.

SUBSTANCE: dual-fuel supply system of a diesel vehicle contains tank of mineral fuel 1, tank of diesel mixed fuel 2, fuel filters 5 and 6, fuel feed pump 7, high-pressure fuel pump 8 with centrifugal speed governor 9, nozzles 10, ultrasonic mixer 11, vehicle onboard electricity supply system power supply 14, electromagnetic motor fuel type switch 15, temperature sensor 19, electromagnetic relay 18 and load sensor 20, made in the form of contact pair 21 and 22, built into centrifugal speed controller 9. In the start-up, warm-up, idling, low and medium loads diesel modes, the electrical circuit of ultrasonic mixer 11 is disconnected from power supply 14 and the fuel is not processed with high-frequency oscillations. In the modes of nominal loads or overloads, load sensor 20 is triggered, the voltage from power supply 14 enters the circuit of mixer 11, which causes the appearance of high-frequency oscillations used for ultrasonic processing of fuel.

EFFECT: invention can be used in fuel injection systems of internal combustion engines.
