FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines (ICE) fuel injection systems. Disclosed are methods for ICE fuel systems operating on gaseous fuel or on two types of fuel. Fuel distributor guide 52 excess pressure can be subjected to response measures by means of gaseous fuel tank valve 32 closing and initiation of diagnostic procedures for determining whether pressure controller 34 is subjected to deterioration of parameters. If pressure regulator is subjected to deterioration of parameters, fuel system one or more components can be adjusted, to enable possibility of fuel distributor guide pressure adjustment.
EFFECT: maintenance of fuel system operating parameters at fuel pressure regulator parameters deterioration.
