HYDROCARBON FUEL VAPOUR FILTER SYSTEM

摘要

A hydrocarbon vapour filter system for capturing vapour released from a fuel tank. The system contains a vapour line in vapour-tight communication with the fuel tank, having a vapour capture segment for capturing fuel vapour, and in the preferred embodiment a purging stage releasing the fuel vapour. During engine operation captured fuel vapour can be released from the vapour capture line into air drawn into the engine intake manifold.
