1. A system for supplying fuel to an engine, the system comprising:

  • a first sensing unit configured to generate signals indicative of multiple operating parameters of the engine, and multiple ambient conditions;

    an adaptive adjustment mechanism in communication with the first sensing unit;

    a pressure regulator having a first valve in communication with a pre-combustion chamber of the engine, and a second valve in communication with a main combustion chamber of the engine; and

    a controller in communication with the adaptive adjustment mechanism and the pressure regulator, the controller configured to;

    receive a signal indicative of a first error associated with a pressure of a fuel supply to the pre-combustion chamber;

    receive a signal indicative of a second error associated with a pressure of a fuel supply to the main combustion chamber;

    receive, using the adaptive adjustment mechanism, an output signal indicative of an adjustment factor determined based on the multiple operating parameters of the engine and the multiple ambient conditions;

    control the first valve of the pressure regulator, based on the signals indicative of the first error, the second error, and the output signal indicative of the adjustment factor, to supply the fuel to the pre-combustion chamber at a first pressure; and

    control the second valve of the pressure regulator, based on the signals indicative of the first error, the second error, and the output signal indicative of the adjustment factor, to supply the fuel to the main combustion chamber at a second pressure.
