Vapour recovery regulation

摘要

A vapour recovery system for recovering fuel vapour from a vehicle tank (18) has a vapour recovery line (6) with a vapour pump (7) for transporting a stream of fuel vapour (V), and control means (2) for controlling the stream of fuel vapour (V). The vapour line (6) comprises a temperature sensor (8) arranged for measuring a temperature (T) of the fuel vapour. The control means (2) determine how much a value representing the measured temperature (T) deviates from a reference value (T ref ) and determine a flow of fuel vapour in dependence of said deviation.
