FIELD: engines and pumps.
SUBSTANCE: liquefied gas supply system includes tank (T) 2 with liquefied gas fuel, fuel pump 3 with supply pipeline (SP) 4 and injectors (I) hydraulically connected to it. Injectors are combined into two groups 5-8 and 9 and connected to electronic control unit 10. Each I group is provided with a drain pipeline connected to the tank. SP of each I group is provided with a controlled valve having a possibility of SP shutting-off. The system includes gaseous fuel temperature 16 and pressure 17 sensors and an ice formation control sensor. In each I group, at least one of the injectors is provided with a temperature sensor. The tank is provided with a heating element.
EFFECT: improving operating reliability of a liquefied gas supply system.
