Abstract
An engine control system for an engine using a primary fuel and a secondary fuel is provided. The engine control system includes a controller configured to determine a first adjusted start of injection to satisfy an engine knock threshold responsive to an engine knock signal value exceeding the engine knock threshold. The controller is further configured to determine, based at least in part on the first adjusted start of injection and a target start of injection, a first adjusted substitution rate of the secondary fuel to adjust the first adjusted start of injection to the target start of injection and determine, based at least in part on the first adjusted substitution rate of the secondary fuel and a target substitution rate of the secondary fuel, an adjusted air-to-fuel ratio to adjust the first adjusted substitution rate of the secondary fuel to the target substitution rate of the secondary fuel.
