Currently there is unprecedented social and political pressure to minimise anthropogenic environmental change. It is a result of the paradoxical nature of emissions reduction that lean-burn technology has become the most likely agent by which future emission targets may be met. However, the inclusion of lean-burn technology requires that the flametube depth is increased, to maintain an acceptable level of pressure drop and sufficient residence time. The injector too must increase in diameter as the admission of air via the fuel nozzle is increased. Maintaining traditional dump style architecture and employing these changes creates a number of additional problems. Most notable is the increased non-uniformity which is inherited by the injector flow as a result of the mismatch between the injector and upstream feed. Injector non-uniformity is a parameter symbiotic with emissions performance and it is therefore imperative to minimise the degree of injector non-uniformity if the ambition of the lean-burn system is to be realised.
