摘要：A method for controlling delivery of fuel from a vapour collection device to the combustion chamber of an internal combustion engine to thereby purge fuel that has accumulated in the vapour collection device by means of a purge flow passing from the vapour collection device to the engine, the purge flow rate being varied by means of a flow control valve located between the vapour collection device and the engine, the method including determining a minimum valve signal value and a maximum valve signal value as a function of the engine load end engine, the method including determining a minimum and maximum extent of valve signal values for controlling the opening of the valve, lecting either the minimum or maximum valve signal value or an interpolation between the maximum and minimum values in dependence on the engine operating conditions to optimi the amount of fuel purged from the vapour collection device to the engine under varying engine operating conditions. In an internal combustion engine having a primary fuel source, and a system for delivering fuel vapour produced in the fuel system of the internal combustion engine to at least one combustion chamber thereof, a method of determining the amount of fuel vapour being purged during clod loop operation of the engine, including: determining the amount of fuel being provided to the engine by the primary fuel source; and comparing this value to a predetermined estimate
of required total fuelling level.
