FIELD: engines and pumps.
SUBSTANCE: set of valves of gas nozzles for gas injection in an internal combustion engine, in which one valve of a gas nozzle has an outer heating element, and one other valve of a gas nozzle does not have an outer heating element. The method to control operation of valves of gas nozzles of the internal combustion engine operating on gaseous and liquid fuels, in which with the help of the outer heating element one valve of the gas nozzle is heated, which is connected to a gas distributor and provides for gas injection into the internal combustion engine. With the stop valve closed between the gas cylinder and the gas distributor and during engine operation on liquid fuel, the heated valve of the gas nozzle is opened for gas injection from the gas distributor into the internal combustion engine, until pressure in the gas distributor is not below the specified value, afterwards leaving the stop valve still closed, valves of gas nozzles are opened, until valve temperature does not reach the specified value. The device to control operation of the fuel supply injector system comprises facilities to detect the starting situation of the internal combustion engine, to close the stop valve of the gaseous fuel injection system and to start the internal combustion engine on liquid fuel with subsequent control of operation of gas nozzle valves according to the method of the claim 2 while the stop valve is retained in the closed condition.
EFFECT: improved operational characteristics.
