It's all emissions. It takes gas vapors and puts them thru the charcoal cannister white then dumps into tank and engine under certain conditions.

interesting why is it beter for emissions if the gas vapors are coleted and then injected into the engine? and what are the conditions for the system to dump the vapors?
