The gas supply system 5 comprises an inlet pipe equipped with an inlet pressure sensor; a pressure relief flame-retarding device installed on the back side of an inlet manifold of the inlet pipe; and a gas common rail pipe fixed to the inlet pipe and provided with a gas inlet adapter and a pressure sensor of a gas common rail pipe. A gas outlet of the gas common rail pipe is provided with a gas injector, and an injection pipe of the gas injector is inserted into an inlet 10 pipe inlet manifold corresponding to each cylinder. According to the present invention, the gas supply system of a dual-fuel diesel engine has a compact and reasonable structure. Each gas jet pipe is installed on the inlet manifold corresponding to each cylinder. The gas is mixed in a cylinder head inlet passage at a fast response speed. Each cylinder can separately control the on/off state of the gas by the gas jet, thereby eliminating scavenging loss within the valve 15 overlapping time.
