The space station life support system generates oxygen and hydrogen, in order to remove carbon dioxide generated by human respiration to the maximum extent, the carbon dioxide and the hydrogen react to generate methane, and then the methane is discharged into the space. Under the vacuum condition, the specific impulse of the gas hydrogen/gas oxygen engine is the maximum when the mixing ratio is 4, and the specific impulse of the methane/oxygen engine is the maximum when the mixing ratio is 3. In order to maximally utilize oxygen, hydrogen and methane generated by the space station life support system to generate thrust for the orbit control engine, total balancing is performed on the life support system and the gas hydrogen, methane and gas oxygen compound engine, and total balance is realized. The novel orbit control engine adopts hydrogen, methane and gaseous oxygen as propellants. 1, hydrogen, methane and oxygen generated by a life support system are used as propellants; 2, the injector (19) is specially designed, so that the injector can be used for both hydrogen and methane; and 3, hydrogen, methane and oxygen react according to a certain chemical equivalent, so that the balance of the whole major cycle is ensured. And 4, the engine adopts a modular design and is divided into an injector (19), a cylindrical section combustion chamber (9) and a sectional type spray pipe (15).
