Natural gas generator set adopting electrical control pressure regulator fuel feed system

The utility model discloses a natural gas generator set adopting an electrical control pressure regulator fuel feed system. The electrical control pressure regulator fuel feed system mainly comprises an electronic throttle valve, a two-stage pressure reducer, an electrical control pressure regulating actuator and the like, wherein the two-stage pressure reducer, the electrical control pressure regulating actuator and an air filter are all connected with a proportional type mixer which is connected with a small-volute booster; the small-volute booster is respectively connected with an intercooler and a silencer, the intercooler is connected with an ignition system through the electronic throttle valve; the proportional type mixer is equally away from the booster, the air filter and the electrical control pressure regulator, at the center position. In such a way, the length of air passages before the booster can be shortened to the utmost, so as to optimize the transient performance of an engine; the fuel gas a
