Abstract

A fuel system for a prime mover includes a controller including at least one processor to determine a primary pressure value for a primary fuel, determine a secondary pressure value for a secondary fuel, and perform a first switch from the primary fuel to the secondary fuel if the primary pressure value is lesser than a first lower pressure threshold value, the secondary pressure value is greater than a second upper pressure threshold value, an operating speed value of the prime mover is greater than a fuel type initialization speed threshold value for the prime mover, an absolute speed error value is lesser than a steady-state absolute speed error threshold value for the prime mover, an operating load to be applied on the prime mover is greater than a rated load of the secondary fuel, and a fuel switchover timer threshold duration from a previous fuel switching event has elapsed.
