The utility model discloses a fuel feed system of a micro-amount diesel ignition direct-injection natural gas engine. The fuel feed system comprises an electric-control common rail ignition diesel feed device and an electric-control common rail high-pressure direct-injection natural gas feed device which are controlled by an electric-control system respectively, the electric-control system adjusts to feed ignition diesel at certain pressure to the natural gas engine according to working conditions of the natural gas engine by controlling a diesel pressure adjusting module of the electric-control common rail ignition diesel feed device, and the electric-control system adjusts to feed main-injection natural gas at certain pressure to the natural gas engine according to the working conditions of the natural gas engine by controlling a natural gas pressure adjusting module of the electric-control common rail high-pressure direct-injection natural gas feed device. The objective of quick low-emission and high-efficiency burning of the engine is achieved by controlling injection pressure of the ignition diesel and injection pressure of the main-injection natural gas through the electric-control system.
