An inexpensive toy projectile launch apparatus incorporating pivotally connected housings which may be quickly and easily assembled. The hand held toy projectile launchers include a flexible plastic launch spring having engaging portions mounted within the housings to enable an operator to move the housings in relation to one another using one hand, with an end portion of the launch spring for engaging and launching a projectile. Each component includes a number of structures such that assembly is simple, but the structure is both robust and inexpensive. The apparatus may launch soft foam darts or soft foam spheres and each launch apparatus includes an elongated strip-like plastic launch spring that bends when primed so as to provide energy for launch.

Methods and systems for controlling reductant levels in an SCR catalyst are provided. In one aspect, reductant levels are adjusted in response to a ratio of change of NOx conversion efficiency to a change of reductant level. In another aspect, reductant injection levels are periodically adjusted to see if NOx conversion efficiency is better or worse at the adjusted levels.
