FIELD: engines.
SUBSTANCE: invention can be used in fuel feed systems of internal combustion engines (ICE). Proposed are methods a system of fuel feed into ICE, in which in response to pressure in the first guide-distributor for fuel 123a located below the threshold value and pressure in fuel tank 20a of the first fuel, which is higher than the threshold value, replacement is performed of fuel injection into engine 30 cylinders of the first, gaseous fuel from the first fuel tank 20a with the second, liquid fuel from the second fuel tank 20b for a certain duration based on the ambient temperature. After that it returns to the first fuel if pressure in the first guide-distributor for fuel 123a has risen above the threshold value, otherwise the system maintains the second fuel injection.
EFFECT: technical result is overcoming some temporary restrictions of gaseous fuel flow in the fuel line without repair and deterioration of ICE operational characteristics.
