An auxiliary fueled pre-chamber ignition system can be used in an IC engine to provide lean limit extension with minimal cyclic variability and low emissions. Geometry and distribution of the pre-chamber nozzles forms an important criteria for performance of these systems since they are responsible for transferring and distributing the ignition energy into the main chamber charge. Combustion performance of pre-chamber nozzle tips with a single jet, dual diverging jets and dual converging jets for a methane fueled pre-chamber ignition system is studied in a rapid compression machine. Upon entering the main chamber, the dual diverging jets penetrates the main chamber in opposite directions creating two jet tips, while the dual converging jets, converge into a single location within the main chamber. Both these configurations minimizes jet-wall impingement compared to the single jet. The total cross sectional area of all three nozzles are maintained the same and the angle between the nozzle holes are kept constant for both dual jet configurations. High speed color images along with pressure measurements are used for assessing the lean limit extension and burn rate parameters of these nozzles. Results indicate that single jet and dual converging jets offers a slightly higher lean limit extension, while the dual diverging jets exhibits faster burn rate.
