Abstract

Official abstract text for this publication.

In an evaporated fuel treatment apparatus, for reducing blow-by of an evaporated fuel component to the outside, the evaporated fuel treatment apparatus includes at least one adsorption chamber filled with a first adsorbent and a second adsorbent that adsorb and desorb a fuel component of evaporated fuel, and the first adsorbent has a higher pore volume than the second adsorbent with respect to effective pores that effectively adsorb and desorb a low-boiling fuel component, and the first adsorbent has a lower pore volume than the second adsorbent with respect to pores smaller than the effective pores and having higher adsorbability and lower desorbability on butane than the effective pores.

First claim

Opening claim text (preview).

The invention claimed is: 1. An evaporated fuel treatment apparatus comprising an atmospheric port side and at least one adsorption chamber, the one adsorption chamber at the atmospheric port side and filled with a first adsorbent and a second adsorbent that adsorb and desorb a fuel component of evaporated fuel, wherein the first adsorbent and second adsorbent are mixed together in the one adsorption chamber, wherein the first adsorbent has a higher pore volume than the second a…
