Inventors

1. A combined fuel system for a tractor gas engine, consisting of a module of cryogenic tanks containing liquefied natural gas, a compressed natural gas section containing a container with compressed natural gas, and equipment for switching the operating modes of the gas engine, wherein the module of cryogenic tanks of liquefied natural gas and the compressed natural gas section of the fuel system are connected to each other through a block of shut-off equipment, characterized in that the line for supplying compressed natural gas to the gas engine is equipped with shut-off valves, wherein one of the said shut-off valves is configured to supply compressed natural gas through a pressure reducer to the gas engine, and the other shut-off valve is configured to supply compressed natural gas through a pressure reducer to feed a heater of the cooling system of the tractor cooling system.
2. A combined fuel system according to paragraph 1, characterized in that it eliminates the need for the tractor to be located near a liquefied natural gas filling station.
