DIESEL ENGINE TWO-FUEL FEED SYSTEM WITH AUTOMATIC MIX COMPOSITION CONTROL Russian patent published in 2018 - IPC F02M43/00 F02D19/06 F02D19/08 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine and can be used in diesel fuel systems. Proposed two-fuel diesel engine feed system contains tank of mineral fuel 1, tank of biofuel 2, line of intake of mineral fuel 3 with coarse filter 4 and dispenser of mineral fuel 5, biofuel collection line 6 with coarse filter 7, electric pump 8 and biofuel metering device 10, as well as membrane actuator 23, stem 22 of which is connected to dispensers 5 and 10 at one end through control and adjustable thrusters 20 and 21. Membrane actuator 23 is connected to radial bore 27 with cavity 28 of diesel intake manifold 29, throttle valve 30 is placed in front of the radial bore 27. Depending on the angle of rotation of throttle valve 30 and changes in the load-speed mode of operation of a diesel engine, the magnitude of the vacuum in intake manifold 27, deflection of membrane 24, rod stroke 22 and the position of the dispensers 5 and 10 change, respectively, and consequently, the ratio of the mineral and biological components of diesel fuel mix.

EFFECT: providing a more accurate ratio of mineral and biological components of diesel fuel mix, depending on the magnitude of the vacuum in the intake manifold of the diesel engine.
