an engine configured to combust more than one type of fuel;
an alternator/generator mechanically coupled to the engine;
a first fuel storage reservoir coupled to the engine and configured to deliver a first fuel to the engine for combustion;
a second fuel storage reservoir coupled to the engine and configured to deliver a second fuel to the engine for combustion; and
a controller configured with executable instructions stored on non-transitory memory that, when executed, cause the controller to;
crank the engine using the alternator/generator in response to detection of a cold start request and initiate fuel injection via fuel injectors with a first ratio of the first fuel to the second fuel when an engine speed reaches an engine speed threshold;
adjust the fuel injection to a second ratio of the first fuel to the second fuel when the engine speed reaches an idling speed, the second ratio lower than the first ratio; and
