The invention discloses a three-valve linkage type variable-component gas engine supply system and a supply method thereof. The invention relates to a gaseous fuel engine supply system. The invention aims to solve the problem that the existing gas fuel engine supply system cannot flexibly adapt to various working environments because the gas components are not combined with the working state of gas utilization equipment. The supply system comprises a tail gas oxygen sensor, an exhaust header pipe, a header pipe gas inlet adjusting valve, a gas inlet header pipe, a gas confluence header pipe, a coal bed gas supply pipeline, a natural gas supply pipeline and a control unit, the header pipe gas inlet adjusting valve is connected to the gas inlet header pipe, and a coal bed gas supply adjusting valve is connected to the coal bed gas supply pipeline; a natural gas supply adjusting valve is connected to the natural gas supply pipeline, the gas outlet end of the gas confluence header pipe is connected with the gas i
