Integrated PZEV module

摘要

An auxiliary fuel vapor adsorption device includes a housing and an activated carbon segment contained within the housing and including a quantity of activated carbon material. A dust separator is also contained within the housing and in fluid communication with the carbon segment, and a canister vent valve is mounted to the housing in fluid communication with the activated carbon segment. The invention allows for the reduction of evaporative emissions by minimizing interconnecting joints between necessary fuel system components.
