Methods and systems are provided for using an engine laser ignition system to take images, in real-time, of a cylinder during combustion and estimate cylinder soot generation. If excess soot generation is determined, cylinder fueling is adjusted by varying an injection pressure, amount, and ratio. An air-fuel ratio of the cylinder is also adjusted in view of exhaust temperature constraints to reduce soot generation.
