METHOD (EMBODIMENTS) AND SYSTEM FOR SUPPLYING FUEL TO ENGINE Russian patent published in 2019 - IPC F02D1/00 F02M37/00 

FIELD: machine building.

SUBSTANCE: disclosed are engine system and methods of controlling pressure of fuel supplied to engine in compliance with compressibility of fuel supplied to engine. In compliance with one embodiment, engine is actuated with fuel pump off to determine compressibility of fuel supplied to engine. Then pressure of fuel supplied to engine is adjusted in compliance with fuel compressibility.

EFFECT: enabling expansion of dynamic range of injector to values providing for accurate adaptation to small volumes of injected fuel, control of pressure of fuel supplied to engine without availability of information on type of fuel or pressure of fuel vapours, control of energy supplied to fuel pump without availability of information on pressure of fuel vapours or its temperature.
