Title:
The discharge control system of evaporativity fuel vapor
Document Type and Number:
Japanese Patent JP6275729
Kind Code:
B2
Abstract:
An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25°C of greater than 35 grams n-butane/L between vapor concentration of 5 vol% and 50 vol% n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25°C of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, an effective butane working capacity (BWC) of less than 3 g/dL, and a g-total BWC of between 2 grams and 6 grams. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.
