Abstract
A combustion control system and method for a turbulent jet ignition engine is presented. A controller is configured to access a trained feedforward artificial neural network (ANN) configured to model a first spark from a first ignition source and maximum brake torque (MBT) based on measured operating parameters, generate the first spark and MBT using the ANN, generate a second spark from a second ignition device, and determine a target spark timing. The ANN can be further configured to receive an input related to spark stagger.
