Development of Low Permeation Plastic Fuel Tube for PZEV Vehicle
Published October 01, 2007 by Society of Automotive Engineers of Japan in Japan
Event: JSAE Autumn Conference
New plastic fuel evaporation tube, which is composed of PBN as fuel barrier layer and polyester/polyester-elastomer as inner and outer layers, was developed to meet PZEV regulation with plastic fuel tank system. This plastic tube shows excellent fuel permeation resistance, compared with conventional ones with fluoropolymers barrier layer. And other performances as fuel evaporation tube are as well as or better than conventional ones. The developed fuel evaporation tube was adapted to new plastic fuel tank system of 07 Model Altima PZEV/AT-PZEV.
