Claim 15:
16. A system of a vehicle, comprising:
an engine comprising a cylinder including at least one intake valve and at least one exhaust valve;
a first fuel system operable to deliver a first fuel to the cylinder via a direct injector;
a second fuel system operable to deliver a second fuel to the cylinder via a second fuel injector located at a different intake system section from the direct injector, and an exhaust gas recirculation (EGR) portion of an exhaust system that is configured to provide exhaust gas to the cylinder; and
a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to:
select a substitution ratio of the first fuel relative to the second fuel based at least in part on an engine load; and
adjust an EGR routing, or an amount of exhaust gas for an injection with the second fuel, in at least partial response to an ignitability value of a combustion mixture in the cylinder that includes the first fuel and the second fuel.
