【発明の名称】低エンジン吸気系真空用蒸発ガス排出装置
Document Type and Number:
Japanese Patent JP2001512211
Kind Code:
A
Abstract:
An evaporative emission control system for a fuel system of an internal combustion engine of an automotive vehicle has a purge flow path through which an evaporative emission containment space of the fuel system for containing volatile fuel vapors is purged to an intake system of the engine. A purge valve controls purge flow through the purge flow path. When the intensity of intake system vacuum falls below a threshold, an electric-motor-driven blower operates to creates a pressure rise in the purge flow path upstream of the purge valve and downstream of the containment space. A differential pressure sensor senses pressure differential across the purge valve, and the purge valve includes an integral valve position sensor, both sensors providing feedback signals to a controller than controls operation of both the purge valve and the blower.
