Abstract
A combustion control system and method for a turbulent jet ignition engine is presented. A controller is configured to receive a torque request, determine a target spark stagger based on a first spark from a first ignition device and a second spark from a second ignition device, determine an adjusted maximum brake torque (MBT) based on the spark stagger, determine a delta spark based on a difference between the adjusted MBT and an actual leading spark from the first and second ignition devices, determine a torque efficiency based on the delta spark, estimate an actual torque, and command a first and a second spark timing from the first and second ignition devices to satisfy the torque request.
