In an engine system of a machine having a multi fuel engine system, an energy accumulator is provide to accumulate and store energy when the engine system is in a low engine power usage or low engine load state, and to discharge energy from the energy accumulator when the engine system is in a high engine usage or high engine load state. The energy accumulator may be implemented, for example, in the form of a gaseous fuel accumulator that delivers gaseous fuel to the engine, a hydraulic fuel accumulator that provides pressurized fluid to power a fuel pump, or a battery pack that powers an electric hydraulic pump.
